probable that specimens “ a — b, 4 -Jr inches long, from the collection of the 
East India Company” now in the British Museum, may have been a por- 
tion of the ten typical specimens of O. piscatorius, McClelland, which 
were presented by him to the East India Museum, (see McClelland’s list in 
Cal. Journ. of Nat. Ilist.,) and now form types of E. alburnus, Gunther. 
3. Barilitts (Pachystomus) radiolatrs. 
Barilius radiolatus, Gunther, Catal., vii, p. 287. 
B. III. D. 2/8, P. 15, V. 9, A. 2/10, C. 19, L. 1. 56, L. tr. 5/6. 
Length of head 2/9, height of body 2/9 of the total length, excluding 
the caudal fin. The specimens in the British Museum are in a very bad 
state, having apparently been dried and subsequently placed in spirit by the 
Messrs, von Schlagintweit, or else when just caught immersed in alco- 
hol which was too strong, and subsequently shaken about until their 
tails were destroyed. — Eyes : diameter 2/7 of length of head, 1 diameter 
from end of snout, and rather more apart. The posterior extremity of the 
maxilla extends to a little behind the front edge of the orbit ; lower jaw 
projects slightly when the mouth is closed. The third suborbital bone near- 
ly reaches the proopercular ridge, Humeral process short. Two pairs of 
short barbels. — Fins : the dorsal higher than long, commencing midway 
between the eye and the root of the caudal fin, its last ray not extending so 
far as to arise above the anal. Caudal apparently deeply forked.

Length of head 2/11, of caudal 2/11, height of body 2/9 of the total 
length. — Eyes : situated in the anterior half of the head, and 3/4 of a 
diameter from the end of snout. Suborbital ring of bones wide, the third 
nearly touching the preoperoular ridge. Upper jaw slightly the longer ; the 
posterior extremity of the maxilla reaches to below the middle of the orbit. 
Rostral barbels extend to beneath the front margin of the eye ; the maxil- 
lary pair minute. Humeral process short. Fins : dorsal two-thirds as high 
as the body below it, commencing midway between the posterior extremity 
of the caudal lobes and the snout ; it is entirely, or all but the last ray, in 
advance of the anal. Pectoral nearly as long as the head, but not reaching 
the ventrals, which last extend half way to the base of the anal. — Lateral 
line : very slightly concave.— -Scales deciduous, two and a half rows between 
the lateral line and the base of the ventral fin. — Colours : back brownish,
