Two perfectly typical young specimens (V. 227-230 ; C. 72, 70) 

 were obtained on the Benito Biver by Mr. Bates. The only 

 difference, apart from the markings, between this species and 

 B. stormsi Dollo resides in the number of scales (23 instead of 21), 

 and it is quite possible the two may have to be united when we 

 become acquainted with a larger number of specimens. 



Hah. Gaboon to Congo. 



72. Elapechis guenthebi Bocage. 

 Hah. Gaboon to Angola ; IVyassaland. 



73. NAIA MELAIfOLEUCA Hallow.

 Africa to Angola and the Zambesi. 



74. Naia goldii Blgr. 



Pseudohaje nigra, Giinth. Cat. Col. Sn. p. 222 (1858), nee Naia

Naia goldii, Bouleng. Ann. & Mag. N. H. (6) xvi. 1895, p. 34, 

 and Cat. Sn. lii. p. 387, pi. xx. fig. 2 (1896). 



Naia guentheri, Bouleng. Cat. t. c. p. 388, pi. xxi., and Ann. & 

 Mag. N. H. (6) xix. 1897, p. 154. 



Naia yakomce, Mocquard, C. E. Congr. Intern. Zool. Leyden, 

 1895, p. 233 (1896). 



Hah. Sierra Leone to Congo. 



A large specimen was obtained by Mr. Bates on the Benito 

 Biver. It has two prseoculars on one side and one on the other ; 

 third and fourth upper labials entering the eye. Scales in ] 5 rows 

 on the neck as well as on the body ; ventrals 199 ; subcaudals 92. 

 Uniform black above. I am now convinced that N. guentheri and 

 N. goldii cannot be maintained as distinct species.

 Hah. Niger to Angola ; Central Africa. 



76. Bins gabonica D. & B. 



Hah. Liberia to Damaraland ; Zanzibar ; Mozambique.
