256 THE EEPTILES OF EGYPT. 
This snake is closely allied to Z. rhodorhachis, Jan, but differs from it in its body being 
less slender, the number of ventral and subcaudal shields falling below the range that 
occurs in that species, in which the former shields vary from 213 to 262 and the latter 
from 113 to 154, whereas in Z. rogersi the ventrals, in five specimens, range only from 
197 to 215, and the subcaudals from 95 to 106. It is also distinguished from Z. rhodo- 
rhachis, Jan, by the rostral shield being considerably broader than high, as its height 
only equals about one-half of its breadth ; whereas in Z. rhodorhachis the height of 
the rostral equals two-thirds of its breadth or even more. The frontal is considerably 
longer than the interval between its anterior margin and the end of the snout. In the 
other details of its head-shields, with the exception of the prefrontals, which are 
occasionally united into one shield (two specimens from Shaluf, near Suez), and in 
the number of scales round the body it resembles Z. rhodorhachis.
