THE KEPTILES OF EGYPT. 
Below I have also given an analysis of the numbers of the ventrals and subcaudals 
that have been recorded, by Mr. Boulenger and others, from Asiatic as well as 
Egyptian specimens. The materials, however, are so limited that little is learned 
from them ; but, at the same time, it will be observed that the lowest number of 
ventrals in the Egyptian specimens is greater than the maximum number from any 
other localities, with the exception of Midian and the Sinaitic Peninsula, and that their 
highest number exceeds by 16 the greatest number yet recorded from any other area 
besides North-western Arabia. The numerical contrast presented by the Egyptian and 
Somaliland snakes is very striking, as their respective lowest numbers are 248 
and 213, and their highest 262 and 229.
