A total of 66 specimens belonging to eleven snake species, some of which were collected during the field studies of 17-31 July and 3-25 September 2003, and some others which have been previously collected and all have been deposited into the collection of ZDEU (Zoology Dept. Ege University), were evaluated taxonomically. 25 of the specimens belonged to Typhlopidae, 37 to Colubridae, three to Viperidae and one to Boidae. These specimens were evaluated from the points of view of pholidosis, pattern and coloration and morphological measurements. Some biological and ecological information were also given with the brief geological history of eastern Mediterranean region. (C) Koninklijke Brill NV, Leiden, 2009.
