of the dorsal fin nearer to the root of the caudal than to the 
extremity of the snout; the anal fin commences at a short 
distance behind the dorsal and terminates a long way from 
the caudal; caudal fin emarginate. All the fins are short- 
rayed ; the pectorals are not much longer than half the length 
of the head and terminate at a considerable distance from the 
ventrals. The root of the ventrals occupies nearly the middle 
between the end of the snout and the root of the caudal fin; 
they nearly reach the vent. Lateral line complete, well 
developed, running along the middle of the body. Back 
greyish, sides and lower parts silvery ; numerous scales on 
the sides blackish. 
This small species grows to a length of 5 inches. Several 
specimens were collected by Mr. Styan in mountain-streams 
near Kiu-Kiang and others at Ichang by Mr. Pratt. 
SCOMBROCYPRIS, g. n. 
Allied to Opsariichthys. 
Scales small. Lateral line running along the lower part of 
the tail. Dorsal fin short, with more than nine branched 
rays, inserted opposite to the ventrals. Anal fin of moderate 
length. Barbels none. Snout prolonged and pointed; cleft 
of the mouth wide, extending to below the eye. The inter- 
maxillaries are much dilated at their anterior end and joined 
in the middle of the snout by a long and firm suture; their 
lateral edge is sharp, not covered by membrane. Lower jaw 
with a pointed hook-like projection in front, fitting intoa hollow 
of the upper jaw. Suborbitals not dilated. Gull-rakers short 
and few in number; pseudobranchie. Pharyngeal teeth in 
a triple series, uncinate. 
The body of this fish is elongate, compressed. I know of 
no other Cyprinoid with equally powerful jaws. The jaws 
are very firmly joined and the sharp bony edge of the inter- 
maxillary and the terminal hook of the lower jaw supply as 
formidable a weapon as if the jaws were actually toothed. 
The form of the snout is very similar to that of a mackerel 
and has suggested the generic name.

The height of the body is nearly one sixth, the length of 
the head one fourth, of the total length (without caudal). 
Head flat and rather broad above. The diameter of the eye 
is two fifths of the length of the snout, one fourth of the post-
