Labeo rilli, sp. nov. 
(Pl; Sxxvill, figs 4.) 
Depth of body 4 times, length of head 43 times in the length. 
Snout shorter than the post-orbital length, the latter 1, to 13 
times the length of the former. There is a narrow groove on either 
side of snout and a slight depression above. Diameter of eye 
slightly shorter than length of snout and contained 3} times in 
the length of head. ‘The inter-orbital length is 1} to 1} in the dia- 
meter of eye. ‘Two minute maxillary barbels. Lips fleshy, lower 
lip finely lobulated. Chin slightly corrugated with concentric 
curves. Dorsal II 10; its origin being equidistant between the 
post-orbital line and the anterior root of the base of anal; length of 
the longest ray slightly longer than length of head; free edge con- 
cave. AnalII5. Length of pectoral somewhat less than length of 
head. Scales 44-46 in lateral line, $; in the lateral transverse and 
6 between lateral line and ventral fin; there are no scales on the 
chest. Caudal deeply divided, both lobes being equal. 
Colour in spirit.—A dark brown dorsal band on the middle of 
the back from nape of the neck to the caudal peduncle; the 
upper two-thirds of the sides is brown, lower third with abdomen 
silvery white. There is a large black blotch on each side of the 
caudal peduncle, commencing on the forty-first scale on the lateral 
line and spreading roundly over about sixteen scales. 
Four specimens from the river Gandak, Saran, collected by 
Mr. M. Mackenzie. Total length from 85 to r00 mm. Local 
name Rilli. 
Labeo tezpurensis, sp. nov. 
(Ply xxx oS 1d 00) 
Depth of body 4 times, length of head 3+ to 3% times in 
the length. Snout broadly rounded with a deep groove on each 
side. Four barbels; two rostrals are minute and are placed at the 
posterior ends of the grooves of the snout; maxillary nearly 
double the length of rostral and half the diameter of eye. Eye 
nearer end of snout than posterior border of head, perfectly lateral, 
3; to 32 times in length of head. Dorsal II 1o—11; equally 
distant from nostril and from root of caudal; upper edge distinctly 
concave. Anal II 5, not reaching root of caudal. Pectoral 14 in 
the length of head, not reaching ventral. Scales—41-42 in the 
lateral line and § in the lateral transverse, 6 between lateral line 
and ventral fin. 
Colour in spirit dark brown above, silvery or dull white 
beneath; fins yellowish white, a faint grey blotch in middle of 
caudal peduncle. 
Three specimens from the Belsiri River, Tezpur, Assam,
