L, — On the Presence of Two Sppxies of Anabas in the 

 White Nile and the Bahr-el-Gebel. By G. A. Boulengek, 

 F.R.S. 



The large series of specimens collected by ]\Ir. Loat has 

 established the fact that two perfectly distinct species of 

 Anahas occur in the White Nile and the Bahr-el-Gebel. 

 Both were confounded by Dr. Giinther in his original descrip- 

 tion of Ctenopo7na Petherici from Gondokoro, I propose to 

 retain the name Petherici for the large specimen figured in 

 Petherick's ' Travels/ the others, the supposed young, repre- 

 senting a smaller species, which I liave pleasure in naming 

 after Dr. J. ]\lurie, who accompanied the Pethericks to 

 Gondokoro and did most of the collecting. 



Anahas Muriei may be detined as closely allied to 

 A. Petherici, but smaller, not exceeding a length of 80 mm., 

 less deep in the body, the depth not exceeding the length of 

 the head, which is 3 times, or a little less than 3 times, in 

 the total length, dorsal spines fewer, and coloration different, 

 the body being covered with numerous black spots, whilst a 

 blackish ocellar spot edged with yellow'ish is situated at the 

 root of, and partly upon, the caudal fin. 



The fin- and scale-formula of A. Muriei is D. XIV-XVl 

 8^10; A. IX-XI 8-11; Sq. 27-28^,; lat. 1. '~'^-. that of 

 A. Petherici being D. XVII-XIX 8-10; A. X 10-11; 

 Bq. 28-30^^; lat.L|gJ. 



A. Muriei inhabits also Lake Victoria.
