I am doubtful whether this fish should not be referred to Cyprinus 
mustha, H. Buch., which, however, Dr. Giinther considers to be the 
Labeo morala; and he remarks, “‘ four barbels as long as the eye ;” 
whereas Buchanan observes, ‘‘it (Cyprinus musiha) differs from the 
description of the mora/a in nothing but the want of tendrils.”

My reason for being unable to accept the genus T'ylognathus, 
Giinther, is, that ‘the separation of this genus from Ladeo is arti- 
ficial,’ being defined in its having nine or less branched rays, down 
to which number Laéeo is included. Thus the existence of an extra 
ray in the dorsal fin, or whether the last double dorsal ray is re- 
garded as one or two might alter the genus of the species. The 
same author has observed respecting the genus Barbus, which has 
been subdivided into several genera and subgenera, ‘‘ Nothing would 
more be contrary to the idea of natural genera, the transition from 
one extreme species to the other being perfect” (p. 84). 
Hab. Rivers and tanks of Orissa. 
Dr. Giinther notices how the subgeneric forms of the genus Barbus, 
as Barbodes with two pairs of barbels, Capoeta with one pair, and 
Puntius destitute of any, pass gradually from one into another. But 
in specimens from India I do not think it will be of common occur- 
rence to find barbels abnormally increased or decreased in numbers. 
I have tried, but hitherto unsuccessfully, to obtain such specimens. 
Even if such were frequent, their abnormal or accidental absence 
will scarcely be considered a sufficient reason against accepting such 
natural subgeneric divisions of this exceedingly extensive genus.
