Show 1903.] ON FISHES FROM SOUTHERN CAMEROON. 21 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 characters, Cynopithecus 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. B o u l e n g e r , F.R.S., V.P.Z.S. [Received November 28, 1902.] (Plates I .-Y .) The freshwater fish-fauna of Cameroon is still very imperfectly known. A small list published by Peters in 1876 1 and another by Lonnberg in 18952 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 llies 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. 1 Mon.
