“ Near Garva lamta (Ham. Buch.), from which differs in having 
7 branched rays in dorsal (in /amta Ham. Buch. 8, as much in 
crenulata Heck., rufa Heck., obtusa Heck.). Lower lobe of caudal 
shorter than head. Total length 75 mm. 
‘““ Barbels 4, very short, uppers $ diameter of eye, lowers 2. 
Pupil in the second half of the head. Ventrals below anterior 4 
of dorsal. Snout projecting strongly beyond mouth. Upper lip 
well developed, not fringed. Width of the mouth less than 4 length 
of head, rather equals the interorbital width. Caudal peduncle 
14-1 times as long as deep. Eye supero-lateral, not visible 
from below. Depth of body 5'0-4'6 in its length (without caudal), 
head 4°5-4°3. Diameter of eye 4°I-4'0 in the length of head, 1°8 
in the interorbital width. Pectorals 5:o-4'8 in the length of body 
(without caudal). Belly covered with scales. 4-5 round black 
spots on the dorsal near its base. A dark vertical bar on the 
caudal peduncle near the base of the caudal. Snout of breeding 
males with numerous conical horny tubercles.

This species is remarkable for its stout facies and very short, 
broad head, which differs considerably so far as the shape of the 
snout is concerned in the two sexes. The dorsal profile behind 
the snout is very nearly straight in the male and only slightly 
arched in the region of the dorsal fin in the female.' The snout 
is rounded and much longer, especially in the male, than the 
part of the head behind the eye. The nostril is very much 
nearer the eye than the tip of the snout. ‘The eye is relatively 
large, especially in the male, in which its length is contained 
in the length of the head about 5 times and in the interorbital 
breadth twice. In the female the length of the eye is contained 
at least 54 times in the length of the head and from 23-3 times 
in the interorbital breadth. The branchial openings extend on 
to the ventral surface, but on the sides do not reach much more 
than half way up the head In the female the snout is smooth 
and very slightly concave in lateral profile. In the male it is 
traversed by two semicircular grooves The first of these, which 
is deep and undercut though narrow, lies a short distance in 
front of the nostril, while the second is about equidistant from 
the first and from the tip of the snout. The short projection 
1 Day’s figure (Fish. Ind., pl. cxxii, fig. 6) is taken from a badly preserved 
specimen.
