"WALTEEINNESIA ^EGYPTIA. 
325 
The only specimens on record of this species were purchased by Dr. Walter Innes 
from a snake-charmer in Cairo, and there is nothing to fall back upon, beyond the 
statement of the juggler, to establish it as an Egyptian species. I have made the most 
careful enquiries about its presence in the neighbourhood of Cairo, without having 
been able to throw any light upon the subject, and Dr. Innes's endeavours to procure 
more specimens have been fruitless. 
Dr. Innes informs me that the snake-charmer in question said that it was known as

The third labial in its upper half enters the orbit much in the same position as does 
the lower prseocular in N. nigricollis, and in exceptional cases of N. haje. Lataste 
mentions that in the type of the genus a second prseocular was formed on the right side 
of the head at the expense of the third labial. 
The genus Boulengerina, Dollo 1 , from Tanganyika, is distinguished from Walter- 
innesia and Naja, according to Mr. Boulenger, by the further extension forwards of the 
palatines. It differs also from the former in the exclusion of the internasal from the 
nostril, and from the latter by its scales not being oblique in their arrangement.
