The bands and feet of the larger species are black, while in the smaller they are golden-fawn. Measurements taken from the dried skin :-Head and body 400 millim., tail 230, hind foot 90, ear 3 0; all these figures must be considered only approximate. Mr. Lydekker exhibited the skull of an English Fox (Canis vulpes) with two perfect canine teeth on each side of the upper jaw (see text-fig. 1). A dog's skull with the upper canine of each side partially divided had been figured on p. 211 of Mr. Bateson's Text-fig. 1. Skull of Fox showing double canine teeth. Study of Variation, and the present specimen would seem to indicate a fuller development of the same feature. A n instance of the full duplication of the corresponding teeth of both sides was afforded by the skull of a Cat figured on p. 225 of the work cited. The Fox to which the skull belonged had been killed by the South Oxfordshire Hounds. The skull itself was the property of Mr. H . G. Pease. In describing the collection of Fishes brought home from Lakes Tanganyika and Kivu by the Tanganyika Exploring Expedition, under the leadership of Mr. J. E. S. Moore, M r . G. A. Boulenger pointed out that the study of this important collection did not modify the conclusions embodied in his first report published in 1898. The exploration of Lake Kivu had thrown no light on the origin of the Tanganyikan fauna; the smaller lake had proved to be very thinly populated with Fishes, which all belonged to widely distributed genera, the species showing a mixture of Nile and Tanganyika elements, with two that might prove to be endemic. The list of the Fishes from the two lakes comprised 91 species, 74 of which had been named by the author. The collection now described consisted of examples of 50 species, 26 of which were 1* |
