Show 324 MR. G. A. BOULENGER ON [Nov. 18, 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 difference 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 Cabul race of the Markhor, the name Chitra' itself not improbably being derived from these spotted rocks. 2. Second Account of the Fishes collected by Dr. W . J. Ansorge in the Niger Delta. B y G. A. B o u le n g e r , F.R.S., V.P.Z.S. [Received October 15, 1902.] (Plates XXYII1. & X X IX .1) In January 1901 2 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 (Phractolseniidse). 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 are represented merely by young specimens. In the case of the Polypteri, which have already been described in these 1 Proceedings' 3, there was no occasion to regret the couise imposed on Dr. Ansorge by the circumstances.
