Eas Gharib, Gulf

• In Egyptian specimens there is very little variation in the number of the ventrals, as 
it only amounts to 9; but in the Hadramut, in Arabia 1 , there are as many as 164 
ventrals, although there is no correspondiug increase in the number of the subcaudals. 
1 By an oversight this species was not included in my account of the reptiles collected in the Hadramut, 
on the expedition of the late Mr. Theodore Bent.
