B. iii. D. 0. P. 11. V. 9. A. 6. C. 19. 



Length of head about ^, of base of dorsal ^ of base of anal about 2 \p of pectoral J, of 

 caudal \ of the total length. Height of head T a , of body i, of dorsal \, of anal j\j of the total 

 length. 



Eyes — Diameter \ of length of head, 1 diameter apart, 2 diameters from end of snout ; no 

 suborbital spine. 



Body elongated, fusiform, cylindrical in front, compressed along the sides. From snout to 

 frontal convex, thence to caudal straight ; interorbital space convex. 



Lower jaw shortest : opening of mouth below, and extending as far posteriorly as half the 

 distance to the orbit ; the end of snout fleshy, and overhanging the mouth ; intermaxillaries pro- 

 duced downwards, and forming a knob, which is in advance of the lower jaw when the mouth is 

 closed. Lips rather fleshy. Cirri, four on snout with their bases not united ; two on superior 

 maxillaries half the length of head. Eyes not covered by any adipose membrane. Nostrils nearer 

 to the eye than the snout ; anterior tubular, posterior broad and open. Opercle rounded pos- 

 teriorly. 



Fins — Dorsal arises slightly in front of the origin of the ventral, and most of it is situated in 

 the anterior half of the body. Anal, is entirely in the posterior third of the body. Dorsal square ; 

 anal slightly rounded ; caudal deeply lobed. 



Scales — Very distinct over the whole body ; none on the head. 



Lateral line — Passes straight from the head towards the centre of the caudal fin, but ceases 

 abruptly opposite the termination of the anal. 



Colours — Yellowish, banded, each band being edged with black; seven along the body, 

 which meet at the lateral line, and consequently are disposed in a V-shape ; one band passes over 

 the opercle, a second through the eye, and a third from the orbit to the angle of the mouth. 

 Dorsal with three irregular rows of black spots. Pectoral, ventral, and anal unspotted, but 

 darkest at their margins. Three oblique black bands on the caudal, which has a black base. 



I am indebted to the Eev. Henry Baker, jun., for this pretty little loach, of which he obtained 

 two specimens on the hills at Mundikyum. 



Habitat — Travancore Hills. 



Nemacheilus rubripinnis. 

 Cobitis rubripinnis, Jerdon, Madras Journal, xv. p. 332. 



B. iii. D. f . A. f . C. 13. 



Length of head \, of pectoral \, of base of dorsal \, of base of anal \, of caudal \ of total 

 length. Height of head \, of body \, of dorsal \, of anal ^g of total length. 



Eyes — Diameter J of length of head, 2 diameters apart, 2 diameters from end of snout. 



Profile ascends to the back of the head, from thence straight to the dorsal fin, from whence 

 it descends gradually to the base of the caudal. 



Mouth fleshy, with six cirri. 



Fins — Dorsal commences just midway between the snout and the base of the caudal, and 

 slightly in front of the commencement of the ventral : anal in posterior quarter of the body.
