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 lino 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 j 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 into a hollow 

 of the upper jaw. Suborbitals not dilated. Gill-rakers short 

 and few in number ; pseudobranchias. 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. 



Scomhrocyp)r{s Styani. 



D. 13-14. A. 13-14. L. lat. 112. L. transv. 19/10. 



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-
