The fishes collected by Dr. Karl Jordan on his expedition to Angola and Southwest Africa are in the collection of the British Museum (Natural History), and have been entrusted to me for description, after prehminary determinations had been made by Mr. Norman. Seventeen species and subspecies are represented, eight of which are here described for the first time. A list of species grouped under localities will be found at the end of this paper. Our knowledge of the fishes of Angola is due chiefly to the work of Steindachner ' and Boulenger. Boulenger's descriptions up to 1916 are gathered together in his Catalogue of African Fresh-water Fishes, and are based mainly on the collections of Welwitsch, Ansorge and Wellman. More recently Nichols and Boulton have described a collection made on an expedition sent to Angola by the American Museum of Natural History, and led by Mr. A. S. Vernay. Angolan species have also been described by Pellegrin, Fowler, and Norman.
