Captain Angus Buchanan's Air Expedition. 1. On a series of small mammals from Kano

T3 Y the kindness of the authorities of the Tring Museum we have been entrusted -*-* with the examination of a number of small mammals obtained by Captain Angus Buchanan, while stopping at Farniso, near Kano, North Nigeria (altitude 1,700 ft.), in December 1919, on his way to explore the unknown regions farther north.These Kano Mammals have proved to be of so much interest and to include so many novelties that we have thought it worth while to give a complete list of them.The most striking form from a zoological point of view is undoubtedly the little short-tailed Gerbil Desmodilliscus buchanani, which represents a genus only discovered in 1917 and hitherto not included in the British Museum collections.The handsome little carnivore Poscilictis rothschildi is also a discovery of some interest, as it greatly extends the known range of its genus, which has only recently been distinguished from Ictonyx.By the generosity of Lord Rothschild, a set of the species obtained by Captain Buchanan, including the types of new species and subspecies, has been presented to the British Museum.The only place towards Kano from which the British Museum has hitherto received any noticeable collection of mammals is the Bauchi Plateau, some 160 miles to the south-east, where the missionary brothers G. T. and J. C. Fox collected a number which formed the basis of papers by Thomas in 1911-12.*Practically all the species, however, prove to be different, and show that the two places are in different faunal areas, of which Kano is strikingly more of a desert character.1.
