^\'hich are close together instead of well separated, and by 

 the forked caudal. In Liohagrus, as in Akysis and Acro- 

 chordonichthys, and also in Amblyceps, the air-bladder is 

 reduced to two small lateral portions enclosed in bone.

Depth of body 5|-5|- times in the total length, length of 

 head 3f-4^ times. Diameter of eye 5-6| times in the length 

 of head,interorbital width Sg- times, length of snout 3j times. 

 Nasal barbel extending beyond posterior border of eye, 

 maxillary barbel to base of pectoral or beyond, post-mental 

 barbel to the edge of the gill-membrane at a point directly 

 posterior to its origin or a little beyond. Upper jaw slightly 

 the longer; width of mouth ^ the length of head. Upper 

 surface of head covered by skin ; supraoccipital process more 

 than twice as long as broad, its length ^ that of the head ; 

 basal bone of the anterior dorsal ray hidden beneath the 

 skin, separated by a short interspace from, or in contact with 

 the supraoccipital process. D. 1 7, the spine smooth, equal 

 to §-| the length of head ; length of adipose tin equal to its 

 distance from the base of middle rays of caudal. A. 17-18. 

 P. I 7, the spine with a series of 5-8 teeth posteriorly, equal 

 in length to that of the dorsal. V. 6. Caudal bilobed. 

 Caudal peduncle twice as long as deep. Greyish, with a 

 few large dark spots or blotches. 



Three specimens, 65-128 mm. in total length. 



Although with less than 20 anal rays, the relations of this
