Nemacheilus triangularis, PL XIV. fig. 1. 
Nemacheilus triangularis, Day , Proc. Zool. Soc. 1865, p. 295. 
B. iii. D. 9. P. 11. V. 9. A. 6. C. 19. 
Length of head about i, of base of dorsal J,, of base of anal about of pectoral 1, of 
caudal ^ of the total length. Height of head of body \, of dorsal of anal of the total 
length. 
Eyes—Diameter \ of length of head, 1 diameter apart, 2 diameters from end of snout; no 
sub orbital 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 Rev. 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 jt, of pectoral of base of dorsal |, of base of anal of caudal of total 
length. Height of head of body of dorsal J-, of anal of total length. 
Eyes—Diameter ^ 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.
