Fins: Dorsal arising in advance of ventrals, midway between tip of snout and posterior base of anal, over ninth scale of lateral line; dorsal rays iii,8, longest branched ray shorter than head; caudal forked, about as long as head; anal rays iii,5, longest branched ray about in head; ventral somewhat shorter than pectorals, which are slightly shorter than head; pectoral rays i, Figure 45.—Lobocheilus cheveyi, new species: Type ( No. 107947). Drawn by Miss Jane Roller. Coloration: Upper half of head and body dark olive, underparts whitish; a jet black median lateral band from head to base of caudal, the band anteriorljr involving parts of two rows of scales and pos- teriorly parts of three rows; scales of body with dark edges; anterior margin of dorsal fin from base to tip black, rays greenish, membranes mostly blackish; caudal dull green, with the black lateral body band extending on median rays; other fins plain. Type.—TYiQ type specimen ( No. 107947), cm. long, was collected by H. G. Deignan, December 25, 1936, in the Menam Mao, a tributary of the Menam Fang, Northern Thailand. Remarks.—This form presents a combination of characters by which it appears to be distinguished from other species known from Thailand and adjacent countries. The most prominent of these characters are the comparatively few scales in the lateral and trans- verse series, the single pair of barbels, rather slender body, obliquely truncate snout, and disti
