EAST AFRICAN REPTILES AND AMPHIBIANS 35 



known specimen. It differs in having 163 ventrals and 34 subcaudals, 

 but that Mearns's specimen is specifically identical I have little doubt, 

 for it agrees precisely with Boulenger's detailed description of all the 

 peculiarities of this rare snake. It measures 424 (350 + 74) mm. as 

 against 270 (235 + 35) mm. of the type.

1 (U.S.N.M. 63378) Kigoma, Lake Tanganyika, T. T. (Raven) 1920. 



Mid-body scale rows, 21 ; ventrals, 194; end of tail missing. Length 

 of head and body only 334 mm. This fine specimen of the somewhat 

 rare aquatic "cobra" of Lake Tanganyika was collected on March 23, 

 1920. In 1926 Mr. Claude Grant, provincial commissioner at Kigoma 

 and well-known ornithologist, informed me that these snakes appear 

 to be getting scarcer each year, though from time to time he still sees 

 one swimming in the lake.

The literature of the Egyptian cobra, as far as East Africa is con- 

 cerned, consists of a number of isolated records from widely separated 

 localities. It is difficult to understand why it should be so scarce when 

 its relative, the black-necked cobra, is so abundant. 



Mid-body scale rows, 21; ventrals, 208; subcaudals, 60; labials, 7, 

 all excluded from the orbit.
