1903. ] ON FISHES FROM SOUTHERN CAMEROON, at 
pithecus and Semnopithecus ; the third and fourth very nearly so, 
the last two characters are found also in Cynocephalus, but are 
more characteristic of Cynopithecus and Semnopithecus. 
It will be seen that if one were permitted to base a classification 
upon cerebral charactersyCynopithecus would have to be removed 
from its position among the Baboons and placed nearer to the 
Langurs; this is not too extreme an interpretation of the brain- 
characters considered on purely morphological grounds. We may 
possibly regard Cynopithecus as occupying a somewhat basal 
position with regard to Cynocephalus on the one hand, and 
Semnopithecus on the other. For, in fact, its characters occur 
in both, though the Baboon-like characters are on the whole less 
marked, 
3. On the Fishes collected by Mr. G. L. Bates in Southern 
Cameroon. By G. A. Boutencur, F.R.S., V.P.Z.5.

(Plates I.-V.) 
The freshwater fish-fauna of Cameroon is still very imperfectly 
known. A small list published by Peters in 1876" and another 
by Linnberg in 1895* are the only contributions that have 
hitherto appeared on this subject. The collection made by Buchholz 
and reported upon by Peters was important as yielding the first 
specimen of the curious Pantodon buchholzi, since rediscovered in 
the Niger Delta and in the Upper Congo and Ubangi. It has now 
been ascertained that this little fish flies or darts through the air, 
and is, in fact, a freshwater flying-fish. . Dr. Pellegrin, of the Paris 
Museum, has kindly informed me that, according to the notes of 
M. J. de Brazza, the specimen obtained in the Congo by this 
explorer was caught by means of a butterfly-net whilst moving 
like a dragonfly above the surface of the water. 
Mr. G. L. Bates, whose previous collections included some very 
remarkable Batrachians described in these Proceedings, has now 
made, at my request, a rather extensive collection of freshwater 
fishes in Cameroon, of which I here give a list, together with 
descriptions of nine new species, one of which deserves to be made 
the type of a new genus. 
The specimens were obtained mostly in the Kribi River, some 
15 miles from the sea; others are from a small tributary of the 
Campo River, near Efulen, Bulu Country, 1500-2000 feet ; whilst 
others again are from the Mvile River, a small stream flowing 
southwards into the Campo, at about the same altitude as the 
preceding. .
