spots, on the caudal ten or more trans verse lines. Pectoral ñus much 

 larger than the ventrals. The rays are — 



D. 15.— A. 6.— P. 10.— V. 7.—C. 17. 



Tenasserim provinces. 



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

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



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

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

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

 trals : the dorsal consistim>' of sixteen rays and the anal of six. A 

 series of twelve to fourteen dark transverse dorsal bands, occasionally 

 íorked or confluent, attenuating and curving backvvard 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 sjmetim.es uniting to form transverse bands on the occiput : 

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

 palé 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 mauy), and the tail slightly furcate. The pectorals 



* To C. biltaeia I refer a specimen from Másuri, 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 Másuri, 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 nuinber and breadth and in arrangement in diíferent 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 Másuri specimens are in the private collection of Major R. C. Tytler. 



f This little nasal process re-appears in Homoloptera bilineata, nobis, 

 described in the sequel.
