not longer than eye, which is contained 3° to 3% times in length 
of head. Inter-orbital width equal to diameter of eye or a little 
greater. Mouth extending to below anterior one-third of eye; a 
pair of rostral barbels, rather long—nearly half the length of head. 
Dorsal II 7; above space between ventral and anals, with last two 
rays of dorsal over the first two of anal; originating midway 
between posterior border of eye and root of caudal; the longest 
ray { or 4 of the length of the head. Pectoral acutely pointed, a 
little shorter than head, not reaching ventral; the latter much 
shorter not reaching vent. Caudal widely forked. Scales—lateral 
: 84 : 
line 47, lateral transverse — and between lateral line and ventral 21. 
Colour.—U pper one-third dark brown, below silvery; pectoral, 
ventral and anal fins reddish yellow, dorsal and caudal sprinkled 
with grey. 
Three specimens, measuring I00, I10 and 115 mm., from 
Bonar, Gharwal, (U.P.), Western Himalayas. 
Danio naganensis, sp. nov. 
(PL xt, figs. 11d. -10:) 
Depth of body 4 times, length of head 4 to 4} times in the 
length. Diameter of eye 3 in the length of head, 2 to 1 in the 
length of snout, I to 1; in the inter-orbital length. Barbels four, 
both pairs close together near the angles of the jaws; maxillary 
pair the smaller, being half the length of the pair in front, the 
latter half the diameter of the eye. Dorsal 10; 20 scales in front. 
Anal II 12; pectoral 13; ventral 8. Scales—4o-42 in the lateral 
line which runs close to the ventral border after descending 
from the gill cleft; in the transverse series 8} above the lateral 
line and 3} below, 23 between the lateral line and the ventral fin. 
Colour in spirit.—A black mark on the back of head and on 
the back, upper half of the side greenish brown, lower half of the 
side and fins dull white. ‘There is a black spot behind the upper 
corner of the gill cleft, a steel grey longitudinal band in the 
middle of the side which runs quite close to the root of the caudal 
growing broader as it passes backwards, and a thin dull silvery 
band just above the steel grey band with traces of a faint one 
below: these two silver lines are almost in juxtaposition with the 
steel grey band. 
Six specimens, measuring 4262 mm., from Lungting River, 
Naga Hills, Manipur.
