Cyrtodactylus kotschyi tinensig n. subsp. is olescribed as ä hew subspecies from Tinos. This subspecies is distinguished from C. k. saronicus by the larger number of tubercles on the thigh. lt` is distributed on Andros too, while Ce k. kotschyi occurs on the Syros-Archipelago, and intermediate popülations between C. k, tinensis n. subsp. and C. k. saronicus ranging over Seriphos, Jyaros, Myconos, Naxe, Ikaria and the adjacent Islands. From-Ikaria, Agama stellio daani n. subsp. is described. It differs from A. s. stellio in its blackish grey instead of yellow or red head, the dark spotted throat and in serological characters. All ^^ A» s`^1^0 whi0^ h-as tieen added to the nominate sub- sp ecTe^~Toj^iirly belong to this subspecies, beside those of the Mycpnos-Archipelago which have to remain to A.s, stellio. The Podarcis erhardi from Syros and Stapod`ia do not belong to P. e. `mykoriensis; they intermediate between this subspecies and` P.e. naxensis. Also Matrix natriy from the Northern Cyclades`does not belong to` N. n^persa but intermediate between this rac?e and H. n> schw`eizerT7 The green`lizards of Tinos are Lacgrta triliheata; this race, now named L. t. citrovittata occurs also on Andros and probably on Mycöno s toQ,`while the L. trilineata of Syros belong to the same race as those from Naxe.` The records of ERHARD, V. HELPREICH and ERBER (partly) were omitted out of the qhecklist as very doubtful. Tab. 2 Shows which kinds of amphibians and reptiles occur on the Northern Cyclades`. The following species were first recorded fropi several Islands in th^s paper: Cyrtodactylus kotschyi (Tragonisi), Hemidae-frylus turcicus (Aridros, Tinos, Hyconos, Jyaros), Agamä^atglljo (Riniaj, PocLarcIs erhardi (Tragonisi, Stapodia, Cherrönisi, Strongylo~7 Schinonisi, Aspronisi, Hegalo and Hikro Gaidaronisi), Ablepharus kitaibelii (Jyaros, Rinia), Elaphe situla (Tinos), Elaphe quatuor—^ `Ij.nea.tj9. (Tipps), Natrlx`.hätriy (Tinos), Confirination is givep` `to many recörds, especially from the last Century (s, £ig. 1, tab. 2). The herpetofaunas of Andros, Tinos and the Myconos- Archipelago are y^ry similar, while that of Syros resembles more those of the Centra,! Cyclades. In summing up the differences between the Northern Cyclades and the •Western or Central Cyclades are rather small. The herpetofauna of Ikaria is rather similar to that of the Northern Cyclades too. But there are large differences between the herpeto- fauna of the Cyclades and that of the mainland and Euboee. In the case of the amphibians and reptiles, the wetland and the terrassed fields, many of them are abandoned now and give rise to phryganas, ma,cchias and secondary `woodlands with all stages of succession, are the most important habitats. But phryganas and intensively cultivated areas were settled by few species only, and in the towns only Hemidactylus turcicus occurs. More extended rocky areas ^ithbüf äny` Vegetation do not bear any amphibians or reptiles. Those species which are restricted merely to wetlands like Bufo bufo, Bufo viridis, Rana ridibunda, M caspica, L`acer.ta trilineata ahd Nafrlx natrix are rather `endangered `on the` Northern Cyclades by habitat destruction, and some populations of these species may have disappeared in the meantime.

Presence of Podarcis erhardii naxensis in Antiparos (central Cyclades) and field notes on the herpetocenosis of the island (Reptilia). -- Presence of Podarcis erhardii naxensis (Werner, 1899) is reported by the author in Antiparos, a small island south-west of Paros (central Cyclades); the lacertid however appears very localized. To explain the reason of this fact the following supposition is suggested: feeding on large invertebrata, Lacerta trilineata limits to small invertebrata the trophic niche of Agama stellio, which owing to alimentary competition, confines P. erhardii to the built up area and high places. The apparently early time (May) of births in Eryx jaculus turcicus local population is also reported.

1. Studies of animal communication have documented myriad rapid, contextdependent changes in visual and acoustic signal design. In contrast, relatively little is known about the capacity of vertebrate chemical signals to rapidly respond, either plastically or deterministically, to changes in context. 2. Four years following an experimental introduction of lizards to replicate experimental islets, we aimed to determine if chemical signal design of the experimental populations differed from that of the source population. 3. In 2014, we translocated Podarcis erhardii lizards from a large, predator-rich island to each of five replicate predator-free islets. Mean population densities increased fivefold over the following 4 years and bite scars suggest significantly more intraspecific fighting among these experimental populations. In 2018, we analysed the chemical signal design of males in each of the experimental populations and compared it to the chemical signals of the source population. 4. We found that males consistently presented a significantly more complex chemical signal compared to the source population. Moreover, their chemical signals were marked by high proportions of octadecanoic acid, oleic acid and α-tocopherol, the three compounds that are known to be associated with lizard territoriality and mate choice. 5. Our island introduction experiment thus suggests that the chemical signal design of animals can shift rapidly and predictably in novel ecological contexts

Im Verlauf einer von der Deutschen Forschungsgemeinschaft finanzierten Reise nach Griechenland bereisten die Verfasser vom 23. bis 29. April 1972 den Paros-Archipel in der Zentral-Ägäis. Der Deutschen Forschungsgemeinschaft sei an dieser Stelle für ihre großzügige Unterstützung gedankt. Danken möchten wir auch Herrn Dr. W. BÖHME, der Vergleichsmaterial aus den umfangreichen Beständen des Zoologischen Forschungsinstituts und Museums A. Koenig in Bonn zur Verfügung stellte, die F. BUCHHOLZ auf mehreren Griechenlandreisen gesammelt hatte. Neben Paros und Antiparos, den beiden größten Inseln, konnten wir mit einem gemieteten Fischerboot den folgenden unbewohnten Inselchen des Archipels einen Besuch abstatten: Despotiko, Strongylo, Tourlos, Preza, Glaropunta und Panteronisi in der südlichen Inselgruppe sowie Ovriokastro und Gaidaronisi vor der Nordküste von Paros. Insgesamt konnten wir hier 13 Arten von Amphibien und Reptilien nachweisen: Rana ridibunda, Mauremys caspica, Cyrtodactylus kotschyi, H emidactylus turcicus, Agama stellio, Podarcis erhardii, Lacerta trilineata, Ablepharus kitaibelii, Eryx jaculus, Elaphe quatuorlineata, Natrix natrix, Telescopus fallax und Vipera ammodytes. Diese von uns im Jahre 1972 eingebrachten Informationen werden ergänzt durch Angaben anderer Autoren (BUCHHOLZ 1955; CLARK 1965, 1967, 1968a, 1968b, 1970, 1971, 1972; WERNER 1938; WETTSTEIN 1953, 1957). Dadurch wird zwar die Anzahl der untersuchten Inseln vergrößert (Spiridonisi, Tria Nisia-Inseln; WETTSTEIN 1957), das Artenspektrum aber nur um Testudo marginata (CLARK 1970) und Elaphe situla (BUCHHOLZ 1955) erweitert.

In June 1973 the Greek islands Amorgos, Thira and Milos were visited. On Amorgos numerous Lacerta erhardii amorgensis and Gymnodactylus kotschi kotschi were seen. Two Eryx jaculus turcicus were met, they are slow animals, one was picked up and stayed very quite. On Thira a lizard, probably Lacerta erhardii naxensis, was photographed. On Milos Vipera lebetina schweizeri and telescopus fallax fallax were seen, caught by a snakedealer.

Investigated the albumins from 31 species and subspecies of the genus Lacerta s.1. by means of the immunoloical techniue Micro-Complement-fixation. Dendrograms were computed by means of the ktch-MargJiash algorithm. Moreover the taxa of the Lacerta saxicola and the Lacerta danfordi comlexes were analyzed by electrophoresis concerning 14 genetic loci. The results were discussel together with karyological and genitalmorphological data so far known yielding the following relationships: Lacerta graeca shows a closer relationshi to the subgenus Podarcis as does the quite closely related species air L. dugesii and L. perspicikata. Lacerta Iaevis probabl is connected closely to Podarcis, too. Lacerta parva shows a closer relationship to the `small izards` than to the sub-genus Lacerta s. str. A clear decision concerning the position of the Lacerta danfordi complex according to chemosystematical data was not possible. It is isolated from the other species probably about as long as L. puma. Biochemical differences between its `species` are too small to confirm their taxonomical revalorisation by Eiselt and Schmidtler Within the Lacerta saxicola complex the investigated taxa show a close relationship. Lacerta praticola and L. derjugini were definitly assigned to this group.

Wall lizards of the genus Podarcis (Sauria, Lacertidae) comprise 17 currently recognized species in southern Europe, where they are the predominant nonavian reptile group. The taxonomy of Podarcis is complex and unstable. Based on DNA sequence data, the species of Podarcis falls into four main groups that have substantial geographic coherence (Western island group, southwestern group, Italian group, and Balkan Peninsula group). The Balkan Peninsula species are divided into two subgroups: the subgroup of P.taurica (P. taurica, P. milensis, P. gaigeae, and perhaps P. melisellensis), and the subgroup of P. erhardii (P. erhardii and P. pelo- ponnesiaca). In the present study, the question of phylogenetic relationships among the species of Podarcis encountered in the Balkan Peninsula was addressed using partial mtDNA sequences for cytochrome b (cyt b) and 16S rRNA (16S). The data support the mono- phyly of Podarcis and suggest that there are three phylogenetic clades: the clade A (P. taurica, P. gaigeae, P. milensis, and P. melisell- ensis); the clade B (P. erhardii and P. peloponnesiaca), and the clade C (P. muralis and P. sicula). By examining intraspeciWc relationships it was found that extant populations of P. erhardii are paraphyletic. Furthermore, subspecies previously deWned on the basis of morphological characteristics do not correspond to diVerent molecular phylogenetic clades, suggesting that their status should be reconsidered. The distinct geographic distribution of the major clades of the phylogenetic tree and its topology suggest a spatial and temporal sequence of phylogenetic separations that coincide with some major paleogeographic separations during the geological history of the Aegean Sea. The results stress the need for a reconsideration of the evolutionary history of Balkan Podarcis species and help overcome diYculties that classical taxonomy has encountered at both the species and subspecies level.

During our vacation on the Greek islands Paros and Antiparos in May 2019 (10.5-20.5. on Paros and 21.5.-25.5. on Antiparos) we were able to photograph the Aegean Wall Lizard (Podarcis erhardii) at several places of which some of them are new records for this lizard. Our photographs illustrate the high variability of the subspecies Podarcis erhardii naxensis, which is widespread on these islands. Despite intense search we were unfortunately not able to find any Cyclades Giant Green Lizard (Lacerta citrovittata). Surprisingly, we found a population of the Yellow bellied Toad (Bombina variegata) near Lefkes. This is the first record for Paros.

With this photo documentation we give a herpetological insight into three vacation trips to the Greek islands of Paros and Antiparos in the years 2019, 2020 and 2021. The focus of our interest was the search for further occurrences of the Aegean wall lizard (Podarcis erhardii naxensis) and the scarce and very shy Cycladic Green Lizard (Lacerta citrovittata). During our excursions, we always had an eye for the accompanying herpetofauna and nature in general, which allows us to introduce some more interesting species in this article.
