and the Suleman types. In size the animal is fully equal to the 

 typical Astor race of the species. The general colour is, however, 

 decidedly darker, the tips of the hairs being blackish brown 

 instead of a kind of blotting-paper colour. The throat-fringe 

 seems also to be somewhat darker; and the under-parts show a 

 decided diflference from those of the Astor race, being at least as 

 dark as, if not actually darker than, the back, instead of distinctly 

 lighter. The resemblance between the two animals is, however, 

 so close as to indicate without doubt that they are races rather 

 than species. 



It may be worth mention that the rocks of Chitral are gneiss, 

 and these present a spotted black-and-white coloration very 

 similar to that of the Oabul race of the Markhor, the name 

 Ohitra^ itself not improbably being derived from these spotted 

 rocks. 



2. Second Account o£ the Fishes collected by Dr. W. J. 

 Ansorge in the Niger Delta. By G. A. Boulenger, 

 F.R.S., Y.P.Z.S. 



[Received October 15, 1902.] 



(Plates XXVIIl. & XXIX.^) 



In January 1901 ^ I had the honour of reporting on a small 

 collection of freshwater fishes made by Dr. Ansorge in Southern 

 Nigeria. Small as it was, that collection proved to be of considerable 

 interest, six species being new and one deserving to become the 

 type of a new family (Phractolfemidse). Encouraged by these 

 results, Dr. Ansorge has continued to collect in the same district, 

 and has enabled me to draw up the following list of 56 species 

 not represented in his former collection ; these, added to the 

 24 species enumerated in the previous list, make a total of 80. 

 Four species are now described as new. 



As on the previous occasion, the difficulty of procuring spirit in 

 sufficient quantity has prevented Dr. Ansorge from preserving 

 any but small specimens. The fishes here enumerated are either 

 small species or ai-e represented merely by young specimens. In 

 the case of the Polyjiteri^ which have already been described in 

 these ' Proceedings ' ^, there was no occasion to regret the course 

 imposed on Dr. Ansorge by the cii'cumstances.
