On Fishes from the Cameroon. 37 
II.—On a Collection of Fishes from the Cameroon con- 
taining new Species. By Dr. Hrnar LONNBERG, 
C.M.Z.8. &e. 
Some time ago I received from my friend Mr. Gunnar Linnell 
a collection of freshwater fishes brought together from three 
different localities of the Cameroon territory, viz. :— 
1. The river at Sanye (also spelt Suny?), not far from the 
sea, but above the influence of the salt water. 
2. Meme River, far inland. 
3. Elephant Lake at the station Johann Albrechtshéhe. 
This collection is not large, but as it contains several species 
new to the territory and also some quite new to science I 
venture to describe it here. 
Isichthys Henry?, Gall. 
Four specimens from the river at Sanye, the largest about 
200 millim. Although known from Liberia to Mayumba, 
French Congo*, this species does not seem to have been 
recorded from the Cameroons before. 
Marcusenius brachyhistius, Gill. 
A single specimen from the river at Sanye. 
Alestes nurse (Riippell). 
Dorsal originating above ventrals. Sq. 25-26 2 1. 
AL lO lGa, Wa 10: 
Height of body 3-3} times in total length f. Length of 
head nearly 4 times in total length. Head longer than high. 
Snout longer than eye. Hye 32 in length of head. Inter- 
orbital space 2}—-2} in length of head. Adipose eyelids 
present. Mouth broader than eye, but the posterior end of 
maxillary well in front of the vertical through the anterior 
border of the eye. Height of caudal peduncle about 4 of its 
length. 
‘There are 16 teeth in the upper jaw, arranged as follows :— 
8 form an inner continuous series; the 8 outer ones are remote 
from each other, and 6 are placed just at the outer margin 
of the jaw, viz. the 2 most median and the 2 most lateral
