spots, on the caudal ten or more transverse lines. Pectoral tins much 

 larger than the ventrals. The rays are — 



D. 15.— A. 6.—P. 10.— V. 7.—G. 17. 



Tenasserim provinces. 



Others have the body proportionally less deep ; as the C. biltaria, 

 B. H. ;* nearly affined to which ranks — 



C. seaiizokata, nobis, n. s. Four well developed cirri above and 

 two below : a minute spinelet above the muzzle (as in C. monoceba, 

 McClelland) :f tail slightly bilobate : pectorals larger than the ven- 

 trals : the dorsal consisting of sixteen rays and the anal of six. A 

 series of twelve to fourteen dark transverse dorsal bands, occasionally 

 forked or confluent, attenuating and curving backward as they descend 

 till they reach the lateral line, below which is a longitudinal row of 

 about twelve irregular blackish spots : head spotted with blackish, 

 the spots sometimes uniting to form transverse bands on the occiput : 

 a black spot surrounded with white at base of tail above : lower parts 

 pale and spotless. Dorsal fin with four or five irregular rows of dark 

 spots : caudal with seven or eight dark transverse lines. Length 

 3|- in., by more than \ in. deep at base of dorsal, and above \ in. 

 broad. Tenasserim provinces. 



The great mass of small spineless Loches have the head shorter 

 anterior to the eyes, the dorsal fin with fewer rays (commonly nine 

 or ten, or not so many), and the tail slightly furcate. The pectorals 



* To C. BiiTABiA I refer a specimen from Masuri, having 12 rays only to the 

 dorsal and 7 to the anal fins ; the black spots on the dorsal and black transverse 

 lines to the caudal being well defined. Length 2| in. It agrees with a speci- 

 men from the Brahmaputra, excepting that the tail-markings are finer and 

 more distinct. 



Another species from Masuri, which agrees in all else with Mr. McClelland's 

 description of C. Montana, is in every respect a typical Cobitis, but has not 

 " a single sub -orbital spine on each side." The zones or bands on the body vary 

 in number and breadth and in arrangement in different specimens, and the dorsal 

 and caudal fins are more or less speckled, in some much more so than in McClel- 

 land's figure. Largest specimen 3^ in. 



These Masuri specimens are in the private collection of Major R. C. Tytler.

 described in the sequel.
