442 Records of the Indian Museum. (Vor. VIF, 
diameter of latter contained 4 times in the length of head and r+ 
times in the inter-orbital width. Lp in fleshy band, interrupted 
in the lower median line. Barbels eight; of the two rostral pairs, 
the upper pair is slightly the longer, 1; times the diameter of the 
eye; maxillary pair the longest and mandibular pair the shortest. 
One pair of bifid and curved spines just in front of the eye (not 
below). Dorsal I 9; its anterior origin being equidistant from 
end of snout and root of caudal, free edge of the fin convex. 
Anal I 5; its tip touching the caudal. Pectoral 14, ventral 8 and 
caudal 20, the latter deeply bilobed. Scales minute and decidu- 
ous, the lateral line is straight, it runs through the middle line 
and is complete. 
Colour in spirit.—A triangular black marking over the snout 
and around black blotch in the inter-orbital space behind which 
on the back there are four black loops, on each side there are 
four broad black transverse bands descending from the dorsal 
loops already mentioned. In the centre of each area bounded by 
these transverse bands there is a round black blotch. The 
pectoral, ventral, and anal fins are white. The dorsal has one 
black spot on the upper third and the caudal has two dark bands. 
One specimen measuring 40 mm., from the Gandak river, 
in Saran, Bihar, collected by Mr. M. Mackenzie. Local name 
Lohachat. 
Lepidocephalichthys annandalei, sp. nov. 
(Pl. xl, figs. 3, 3a, 30.) 
Depth of body 5: to 6 times, length of head 4 to 4: times in 
the length. Snout 3 to 3} times in the length of head and 1:—1} 
times as long as the diameter of eye, the latter contained 43 to 5 
times in the length of head and equal to the inter-orbital width. 
Mouth inferior. Barbels eight, allsmall. Dorsal I 7; the anterior 
origin equidistant from the anterior margin of the eye and the root 
of the caudal. Anal II 5. Pectoral 7—8, with a slight padding or 
cushion-like thickness over two of the outer rays. Caudal 16—18 ; 
notched in the middle, in some cases the margin of the fin is 
lunate by considerable shortening of the middle rays. Body 
variegated with collections of brown and grey spots arranged in 
patches; the dorsal is faintly banded and the caudal is obliquely 
banded with three faint grey bars on each side of the middle line. 
There are two intensely black spots encircled in white rings in the 
caudal fin, one of these is placed slightly above the middle line 
near the middle notch at the outer margin of the caudal fin, and 
the other at the base of the caudal fin slightly above the middle 
line. The intensely black spot in the middle of the outer maigin 
of the caudal fin and its notched or concavely lunate outside 
border are very distinctive and constant characters. 
Seven specimens measuring from 33 to 42 mm., three from 
the river Mahananda at Siliguri collected by Dr. N, Annandale,
