HEMIDACTYLUS TUJBCICUS. 85 
number on the pollex. Six is exceptionally present in H. turcicus on the pollex, but 
it is common in sinaita ; whilst 8, which is not uncommon in the former, is so in the 
latter. On the fourth finger the lamellae of //. turcicus vary from 8 to 10, and in 
sinaita from 7 to 8. The latter number is the most prevalent in both. 
On the hallux of H. turcicus the lamellae vary from 6 to 8, and in sinaita from 5 to 8 ; 
the most prevalent number in the former being 7, and in the latter 5. 
On the fourth toe in H. turcicus the lamellae vary from 9 to 11, and in sinaita from 
8 to 11. In both 10 is the most prevalent number. 
In six males of 11. turcicus from Egypt, the praeanal pores range from 6 to 8, the 
numbers being 5, 6, 6, 7, 7, 8 ; but in 14 examples of var. sinaita from the Eastern 
Sudan they vary from 2 to 5, only one has 2, two have 5, and the remainder have 4 ; 
whereas in one from Western Somaliland there are 6 praeanal pores. 
In view of how the supposed characters of H. sinaitus have broken down with the 
investigation of additional material, it is not entitled to more than varietal rank, based 
chiefly on the differences observable in the lamellae, and more or less in the formation 
of the nostril. 
It is found in the Sinai tic Peninsula, Aden and its neighbourhood, Western Somali- 
land, and the Eastern Sudan to Kosseir (Klunzinger). 
The native name for this species is simply uoj, or bars.
