INDIAN CYPRINID#. 
PLATE XXXIX. 
Fig.1. Oreinus guttatus,J.M. Drawn the natural size of a specimen 
brought down from Boutan by Mr. Griffith. It belongs to the new 
sub-genus of Mountain Barbels; but the minute serrations on the 
hinder margin of the first ray of the dorsal fin are not shown in the 
figure, and the cross lines on the lower parts of the body are not 
natural, having been occasioned by keeping in spirits. 
Fig. 2. Barbus hexastichus, J. M. An important species, inhabiting most of 
the large rivers in the north-eastern parts of Bengal. Its colours 
are probably subject to variation; but during the cold season all I 
met with in Assam were as represented in the drawing, which is 
about one-fifth of the natural size of the fish. 
Fig. 3. Barbus diliciosus, J. M. Half the natural size. 
Fig. 4. Barbus spilophilus, J. M. Half size from a specimen in spirits, 
found by Mr. Hodgson, and presented by him to the Asiatic Society; 
it is probably the Cyp. chagunio of Buch. The two long filaments in 
the anal are only, I suspect, an individual peculiarity. 
PLATE XL. 
Fig. 1. Gobio bicolor, J. M. Natural size. 
Fig. 2. Gobio anisurus, J. M. Natural size ;—both are Bangons of the natives. 
Fig. 3. Cyp. curchius, Buch. Half size; it is very nearly allied to Fig. 2, 
Pl. 38.
