forms a flat wrinkled outer surface ; found at the source of the Cahul 
River. G. sulcatus ; an oval disc on the breast, between the pectorals, 
composed of cross plates ; and a row of similar plates on the broad under 
surface of the first ray of the abdominal fins ; D. 8 ; P.13; V. 7 ; A. 9 : 
Kasyah Mountains. G. striatus ; eight barbules ; a striped suction 
surface on the breast ; B. 8 ; D. 8 ; P. 11 ; V. 6 ; A. 9 ; Kasyah Moun- 
tains. G. pectinopteriis ; eight barbules ; striped on the breast ; B. 9 ; 
D. 8 ; P.9; V. 6 ; A. 7 : Simla Mountains. G. lahiatus ; lips enveloped 
with many flaps, and so broadened round the mouth, that they form 
a broad flat sucking disc ; anal fin very small ; dorsal without spines ; 
adipose fin long ; barbules very short ; D. 7 ; P. 11 ; V. 7 ; A. 6 : Mish- 
mee Mountains. From the formation of the lips, should this species not 
form a peculiar genus ? 
McClelland describes another new genus of the same family, 
which he calls Olyra. Its characters are : — 
Body soft, long, and cylindrical, with two dorsal fins, the first radiated, 
the second adipose ; head elongated, and flat at the snout ; the gill cover- 
ing ends posteriorly in an oblique point turned towards the dorsal fin ; 
anal long, caudal entire ; teeth velvety ; no dorsal spine ; six to eight 
thin barbules. O. longicaudatus ; a rough spine before the pectoral 
fins ; jaws equal in length ; six bristly barbules ; the middle ray of the 
caudal fin elongated into a point ; B. 6 ; D. 7 ; P. 1. 6 ; V. 5 ; A. 23. 
The author observes, in this species, a union between the Shad-fish 
and Cobites. 0. laticeps ; under jaw longer than the upper ; head 
anteriorly very low ; eyes small and vertical ; the rays of the anal fin 
increase in length posteriorly ; six or (?) eight thin barbules ; B. 13 ; 
D. 7 ; P. 9 ; V. 7 ; A. 15 : Kasyah Mountains.

The sixteenth volume of the great Histoire Naturelle des Poissons, 
par Cuvier et Yalenciennes, appeared in 1842, and contains the com- 
mencement of the family of the Cyprinoids, viz., the genera Cyprinus, 
Barbus, Labeobarbus, Schizothorax, Tleckel; Oreinus, M‘ Cel- 
land; Dangila, Yal., Rohita, Yah, Capoeta, Yah; Cirrhinus, Cuv., 
Gobio, Cuv., Tinea, Cuv., Labeo, Cuv. In an appendix, the author con- 
demns the divisions of the Cyprinoids made by Hamilton, Buchanan, 
and John McClelland, and tries to reduce them to the genera above 
mentioned. He then gives the species with barbules, which he thinks 
doubtful ; their number is considerable. 
Dangila, Yal., has a long dorsal fin, without an anterior spine ; a
