This species is closely related to D. jerdoni, but can be dis ~ 
tinguished at once by the structure of the snout and by its relatively 
longer head. ‘The snout, im both sexes and at all ages, is greatly pro- 
duced in front of the nostrils, forming a regular conical forwardly- 
directed process, which however does not extend as far forward as 
the actual tip. As in D. jerdoni, this process is formed by a semi- 
circular groove which passes below it. It bears at its free extrem- 
ity two rows of spiny tubercles. There is a second groove some 
distance in front of the first which transforms the actual tip of the 
snout into a second process, which is directed forwards and slightly 
upwards and bears a number of small spiny tubercles on its posterior 
surface. The dorsal fin is rather less high than in D. jerdoni and 
the two larger unbranched rays are thicker and stouter. A third 
(anterior) unbranched ray may be present or absent. The pec- 
toral fins are relatively short and narrow, rounded at the tip and 
oblique. The chest is not so flat as in D. jerdoni. ‘The scales are 
rather smaller, though of the same number in the lateral line. 
There are 33 between the lateral line and the dorsal fin and 24 or 3 
between the former and the ventral. 
The colour of fresh specimens is as follows :—the sides and 
back pale yellowish above changing to pink below. All the fin- 
rays are somewhat infuscated and there is a row of dark spots 
along the base of the dorsal fin. An obscure dark mid-lateral line 
extends from behind the head on to the caudal fin. ‘The iris is 
golden yellow. The colours have faded considerably in specimens 
in spirit. 
I have examined thirteen specimens, the largest of which is 
go mm. long. The snout is produced in individuals less than two 
inches long. 
Distribution.—vThis fish is only known from the base of the 
Nilgiri Hills. My specimens were taken in a small muddy stream 
(the Nierolay) which runs into the gorge of the Bhavani River 
some I2 miles above Mattapolaiyam in August.

This little species is also closely related to D. jerdoni, but 
the eyes are in the middle of the head, the head is large and the 
structure of the snout is different. The three specimens I have 
examined are perhaps not fully adult, but the secondary sexual 
characters are fairly well developed. The length of the head is 
contained in the total length a little more than five times. The eye 
is very large, its length being contained a little more than four times 
in the length of the head. The dorsal profile of the head is convex 
in the female. In the male there is a short process between the 
nostrils, bearing several relatively large spiny tubercles. ‘The
