In the single specimen described by Miss POPTA Ph. Dr. 

 (see note pn page 9) from Borneo, we find the height and the 

 caudal as in H. wassinki, but the eye and the position of 

 the dorsal is as in H. ocellata. As also H. ocellata is founded 

 on a single specimen, we think it possible, that H. ocellata 

 and H. wassinki belong to one and the same species.

D. 9; A. 9; L. 1. 60. 



Head broad, its profile arcuate, snout much longer than 

 postocular part of head. Lips not fringed. Barbels short, thick 

 and twice the diameter of the eye. Eye small, situated in the 

 posterior part of the head, its diameter is '/ 3 of the interorbital 

 space, and ! / 4 of the length of the head and } J 2 the length of 

 the snout. Head J / 4 of total length. Origin of the dorsal oppo- 

 site to the last internal ray of the ventrals. Pectorals as long 

 as head, nearly reaching ventrals. Caudal slightly emarginate, 

 its lobes quite equal. Colour in alcohol yellowish, marmorated 

 with brown. A black band at the base of the caudal. Fins 

 yellowish, immaculate. [After Perugia, not seen by us].

Height 8 ] / 2 in total length. Head 6 in total length, its 

 breadth about i ! / 3 in its length. Eye 6 &\ v less than twice 

 in the interorbital space, situated for its greater part in the 

 hinder half of the head. Snout obtuse, as long as the remaining 

 portion of the head. Barbels subequal, slightly shorter than 

 eye. Lips not fringed. Origin of dorsal slightly behind origin 

 of ventrals, separated by 30 scales from the occiput. Dorsal 

 acute, slightly emarginate, higher than body, shorter than high. 

 Anal acute, its height equal to that of body. Ventrals not 

 reaching anal, subequal to pectorals, which do not reach ven- 

 trals. Caudal emarginate, its lobes acute, the inferior slightly 

 the longer, 5 times in length. Ventral surface scaleless, scales only
