Squamation: Lateral line complete; scales deficient on abdomen; scales in lateral line 37, in transverse series from midline of back to base of ventral fin ; predorsal scales 21; circumpeduncular scales 14. Fins: Origin of dorsal fin posterior to origin of ventrals, verj^ slightly nearer to base of caudal fin than to tip of snout; depth of body % height of dorsal fin, dorsal rays ii, 7; caudal fin about length of head, deeply emarginate, lobes pointed; anal rays i, 6, origin of fin nearer to base of caudal than to base of ventrals; ventrals shorter than pectorals, not reaching anal opening, rays ii, 7; pectorals shorter than head, extending to ventrals, rays vi, jjyh^^' â "'^'^â¢'-^'^^'-^-^^\-';'l35l Figure SS.âHomaloptera lineata, new species: Type ( No. 119488). Drawn by Mrs. Alice C. Mullen. Coloration: A narrow reddish-brown band along lateral line from head to base of caudal fin; body and head otherwise whitish; fins hyaline, unmarked. Type aiid paratype.âThe type ( No. 119488), cm. long, was collected by H. G. Deignan in the Mekong at Chiengsen Kao, Northern Thailand, January 12, 1937. A paratype cm. long ( No. 119489) was taken at the same place and time. Remarks.âThe relationship of this species to the other members of the genus found in Thailand is sufiiciently indicated in the foregoing key. This form is distinguishable from various other species of the East Indian Archipelago, Burma, and India, by its relatively few
