tained five and a half times in the total length (without 

 caudal), the length of the head four times and a fourth. 

 Head low, with the snout much elongate and pointed, the 

 eye being rather nearer to the gill-opening than to the end of 

 the snout ; the projecting part of the snout is swollen, conical, 

 the mouth being entirely at the lower side of the snout. Eye 

 one fifth of the length of the head, less wide than the flat 

 interorbital space. Upper lip swollen ; lower very short, 

 broadly interrupted in the middle ; barbel very short, lying 

 in a groove which extends forward to near the extremity ot 

 the snout. Gill-membrane attached to the side of the isthmus. 

 The origin of the dorsal fin is considerably nearer to the end 

 of the snout than to the root of the caudal ; ventrals inserted 

 below the posterior half of the dorsal. Caudal deeply forked. 

 The pectorals are much shorter than the head, and scarcely 

 extend to the origin of the dorsal fin. The lower parts of 

 the head and of the thoracic region entirely scaleless. Color- 

 ation transparent, without any spots. 



One specimen, 4 inches long. 



This species differs from Rhinogohio typus in having a much 

 smaller eye and in having the lower parts of the thorax 

 scaleless. 



Hemiculter leucisculas^ Kner, 



This species is subject to variations with regard to the 

 width of the third suborbital bone and the position of the 

 ventral fins. In specimens from Ichang the third suborbital 

 is broad enough to be in contact with the praopercular limb, 

 whilst in specimens obtained in the lower parts of the river 

 there is a more or less broad strip of soft skin intervening 

 between suborbital and pra3operculum. In the specimens 

 from Ichang the root of the ventral is opposed to the first 

 dorsal spine, whilst in the majority of our other specimens 

 the whole of the ventral is in advance of the dorsal. 



Homaloptera jimhriata. 



D. 11. A. 7. P. 19. V. 11. 



This species differs from the typical species of Ilomaloptera 

 in the shape of its snout and in the arrangement of the 

 barbels. The snout is flat and spatulate, considerably nar- 

 rowed in front and nearly as long as broad ; the mouth is 

 surrounded with fringes, from which the barbels diff"er only 

 by their greater size ; the barbels and fringes of the upper
