The height of the body is contained five times in the total length 

 (without caudal), the length of the head four times and one-third ; 

 the diameter of the eye is rather more than the length of the snout, 

 and somewhat less than one-third of that of the head. Snout ob- 

 tuse, convex, slightly overlapping the mouth ; the maxillary does 

 not extend to below the front margin of the orbit. Suborbital ring 

 very narrow. The origin of the dorsal fin is midway between the 

 end of the snout and the root of the caudal ; its spine is strong, but 

 shorter than the head. Caudal fin forked. The pectoral fin termi- 

 nates at a considerable distance from the ventral. Uniform sUvery. 



The pharyngeal teeth of the two inner series are exceedingly 

 slender.

 Dr. Bleeker has indicated a fish from China which may be iden- 

 tical, or at least congeneric, with the above species. Although the 

 specimen was in too bad a condition to give a descriptton of it, 

 Dr. Bleeker named it Acanthohrama simoni, Nederl. Tydschr. Dierk. 

 1864, p. 25. He says that the pharyngeal teeth are- in a single 

 series; but then, those of the inner rows are so slender iu our spe- 

 cimen that they may be easily overlooked or lost.
