free portion of the tail is two-thirds as high as long. The diameter 

 of the eye is two-sevenths of the length of the head, scarcely less 

 than that of the snout, and much more than the interorbital space, 

 which is very convex. Mouth of moderate width, subvertical, the 

 maxillary not extending to the vertical from the front margin of the 

 eye. Suborbital ring very narrow. The second dorsal spine is of 

 moderate strength, three-fourths of the length of the head. Pectoral 

 fin shorter than the head, extending to the ventral. Coloration 

 uniform silvery.

I am unable to find distinctive characters of Culler alhurnus, Kner, 

 l^ovara, Fisch. p. 3G2, He says that the interorbital space is only 

 half as wide as the diameter of the eye ; this is also the case in 

 C. recurviceps. 



2. Culter brevicauda. 



Closely allied to C. recurviceps, but with the entire abdominal 

 edge trenchant, and shorter tail.

The height of the body is contained thrice and three-fourths in 

 the total length (without caudal), the length of tlie head four times. 

 Abdominal edge trenchant from the pectorals to the anal. Nape of 

 the neck convex. The free portion of the tail is as high as long. 

 The diameter of the eye is two-ninths of the length of the head, 

 rather less than that of the snout, and more than the interorbital 

 space, which is very convex. Mouth of moderate width, subvertical, 

 the maxillary not extending to the vertical from the front margin of 

 the eye. Suborbital ring very narrow. The second dorsal spine is 

 of moderate strength, three-fifths of the length of the head. Pec- 

 toral fill not quite as long as the head, extending to the ventral. 

 Coloration uniform silvery. 



Air-bladder tripartite, the hindmost partition being minute. Pha- 

 ryngeal teeth slender, hooked, 5.4. 2 — 2 . 3 or 4 . 4.

Kichardson has described from figures two Chinese fishes which, 

 if the characters indicated by the artist be correct, would appear to 

 belong to a distinct genus, though evidently allied to Culter, from 

 which they difi'er in having the lateral line bent downwards in an 

 abrupt curve behind the pectoral fin. I abstain from naming the 

 genus, as such materials generally prove more or less deceptive : —
