THE EEPTILES OF EGYPT. 
account of the habits of Eryx jaculus in confinement, it would appear that the members 
of this genus fall a prey to Varanus griseus. 
1 have heard two names applied by the natives of Egypt to this snake and to Eryx 
jaculus. The first, and that most commonly used, is .Id 5 = dassas. According to 
Ulfaz Udwujeh, jlCS = dassas, a noxious kind of serpent, and LjCj = dassdsat, an 
earthworm living underground. The other term I have heard applied to Eryx jaculus 
I wrote down at the time as terayshay. I am also informed that it is known as 
<oUj 'Ly=~ = haya daffana, the burrowing snake. All of these terms, however, require 
investigation by a competent Arabic scholar. 
In the accompanying table will be found a record of some of the variations met 
with in this species.
