] BARBOUR — REPTILES FROM SINAI AND SYRIA 81 



Museum in connection with those which Dr. PhilHps secured, that 

 three very distinct and easily distinguished races are found within 

 the range of the species. 



P. lobatus lobatus (Geoffroy) was originally described from Egypt, 

 as was Gecko ascalabotes of Merrem (Tentamen, 1820, p. 42). 

 This was nothing but a substitute name, as was also the name 

 Ptyodadylus hasselquistii of Dumeril and Bibron (Erp. Gen. 3, 

 1836, p. 378, plate 33, fig. 3). Riippell's P. guttatus also prob- 

 ably is based on the typical form. M. C. Z. no. 1054, consisting of 

 two well-preserved specimens collected in 1855 Jpy H. H. Ward at 

 the Temple of Sakkara, not far from Cairo, Egypt, are topotypes 

 of this race. Besides occurring in Egypt, it was found abundant 

 by Dr. Phillips at Feiran, Sinai, and Akaba and Petra in northern 

 Arabia. The large series from Ain Musa, near the north end of 

 the Dead Sea, is slightly atypical, but may still be considered to 

 represent the Egyptian form. 



Lataste gave the name P. oudrii (Le Naturaliste, 1880, p. 299) 

 to specimens from Bou Saada in the Algerian Sahara. He sent 

 three cotypes to the Museum of Comparative Zoology (no. 4639), 

 and these represent a strongly marked Algerian race, which is 

 distinguished by the small eye and the ear opening, when compared 

 with the typical form. All of our specimens are a deep rich brown 

 in color, almost uniform. The entire series of P. lobatus lobatus, 

 numbering some thirty specimens, are ashy gray, not infrequently 

 with light yellowish cross-bars. Thus the Algerian race stands as 

 Ptyodadylus lobatus oudrii (Lataste). It may be further distin- 

 guished by the shorter and stouter limbs, the legs and arms in the 

 typical race being extremely long and slender. 



A third race appears about Mount Hermon, and it is apparently 

 the best differentiated of the three. It may be known as 



Ptyodactylus lobatus sancti-montis subsp. nov. 



Type, an adult, M. C. Z., no. 9757, collected at Rasheya, base of Mount 

 Hermon, Syria, May 20, 1914, by W. M. Mann. 



Similar in habit to P. I. oudrii, but stouter still and with even shorter 

 limbs and larger eye and ear opening. Eyes more nearly as in the typical
