226 INDIAN CYPRINID&. 
consist of species whose habits accord with the views of Cuvier and Linnzus : 
and Sarcoborine or carnivorous Cyprins, consisting of several natural ge- 
nera; and Apalopterine, including the Cobitine or Loaches, the Peciliane, 
Cyprinodons, and other genera which in the Regne Animal appear to have little 
connexion with the family, as well as some new forms peculiar to India. 
13. As the peculiarities of the first sub-family, consisting in the form 
of their mouth and digestive organs have been pointed out, I shall now 
proceed to notice the characteristics in structure and habits of the several 
groups of Sarcoborine. Two of the most remarkable genera of this sub-family 
are the Perilamps and Opsarions; the first, consisting of small insectivorous 
fishes remarkable for the brillianey of their colours, always disposed in streaks. 
The second are lengthy handsome species, larger than the Perilamps, though 
still of small size and very bright in their colours, which are however disposed 
in cross bars,—these are exclusively carnivorous, and remarkably voracious. 
14. The Perilamps (Perilampus) form the connection between the 
Systoms and Leucises. The mouth is placed in a directly opposite posi- 
tion from that which it occupies in the typical forms of the Peonomine ; 
the jaws are directed upward, and their apices are placed on a level 
with the back or erown; their intestine is short, and in no instance exceeds 
the length of the body, and their food consists of insects only, which they 
derive by springing from beneath the surface of the water, thus forming a 
direct contrast to the Gonorhynchs and other Peonomine whose food is 
exclusively derived from sandy, rocky, or muddy bottoms. Eleven or twelve 
species of this new genus are described in this paper. 
15. The Opsarions (Opsarius) differ from herbivorous Cyprins still 
more widely in their economy and habits. " The body is long, the mouth 
widely cleft and horizontal, and though without teeth, the symphysis of the 
lower jaw is armed with a sharp hook in the more characteristic, but which is 
blunter and less prominent the further we pass from the most typica
