376 INDIAN CYPRINIDZ. Sarcoborine. 
Lond. 1838, has reached me, and affords many observations in corroboration 
of the results to which I have been led in the analysis of Indian Cyprinide, 
particularly in the formation of the aberrant groups of the family. Speaking 
of the apodal order, to which the Gonorhynchs present many relations, as well 
in their lengthened cylindric forms, thick integuments, and submaxillary 
sucker with which they are furnished, Mr. Swainson says, ‘it would seem, 
indeed, that nature upon leaving the annulose circle, and entering that of the 
fish, intended to show us all the forms of variation in the first group, which 
she afterwards employs to characterise higher divisions: this she has done 
in the class Acrita, as Mr. Macleay has so beautifully illustrated in the “ Hore 
> 
Entomologice ;” and in confirmation of this, we now find the apodal forms 
reappear, not alone among the Peonomine as in the Gonorhynchs, but also 
in the Platycara and Cobitine, thus marking the most distant groups with 
certain types, through which the character of annulose animals, or worms, 
may be traced. Unacquainted before with this analogy, yet in the formation 
of aberrant groups I have been led to the development of its truth by another 
path, than the one which led to its detection by Mr. Swainson. 
Ii.—Svus-ram.—_ SARCOBORINA, J. M. 
CHARACTERS.—A blunt knob on the apex of the lower jaw, more or less distinct ; 
intestinal canal short ; colours bright. Like the Peonomine, they are confin- 
ed to fresh water, but their habits are carnivorous ; size small. Three rays 
in the branchial membrane. 
The first object is to show that the relations of this sub-family to the 
Peonomine are parallel, and therefore that the two groups are distinct. The 
number of types representing genera in each sub-family are apparently five, 
some of them are very well made out ; as for instance, Cirrhinus, Barbus, 
Gobio, and Gonorhynchus among the Peonomine ; and Systomus, Perilampus,
