Fishes from the Cameroon. 39 
another strongly mutilated, both from Meme River, far 
inland. 
This species does not appear to have been previously known 
from the Cameroons, although recorded from Gaboon, the 
Gold Coast, and Ubangi. 
Clarias bythipogon, Sauvage. 
Three specimens from the river at Sanye, the largest 
measuring nearly 30 centim. in total length. It may thus 
be the largest known specimen of its kind. In his work 
‘ Les Poissons du Bassin du Congo’ Boulenger has recorded 
23 centim. 
Auchenoglanis guttatus (Lonnberg). 
A specimen from the Meme River, far inland. 
Malopterurus electricus (Gmelin). 
Several specimens from Sanye and the Meme River.

* I take the liberty of dedicating this new species to Mr. G. A. 
Boulenger, who has done more than anybody else to increase our know- 
ledge of the West-African fishes.
