The Tanganyika problem; an account of the researches undertaken concerning the existence of marine animals in Central Africa . he head, not reaching the ventral, which is inserted under the first rays ofthe dorsal. Caudal forked. Caudal peduncle twice as long as deep. Scales 68-70 — -, 9 or 10 between the lateral line and the root of the ventral. H—15Olive above, each scale darker at the base, silvery white beneath ; fins greyish. Total length, 320 millim. Described from three specimens from the north end of Lake Tanganyika. The discovery of a species of this genus in Lake Tanganyika is particularlyinteresting from the fact that only one was known from Africa, viz., the Abysin-nian C. dilloiii, C. and V. ; this is distinguished by the absence of barbels and thegreater size of the scales (30 to 32 in the lateral line). In the presence of a pair ofbarbels and the small size of the scales, C. tanganica belongs to the typical sectionof the genus, inhabiting south-western Asia; but it has the enlarged dorsal rayneither feeble, as in C. fundulus, Pall, and allied species, nor serrated, as inC. trtitta, Heck. Ik.
