body. Anal inserted about midway between origin of ventrals 

 and base of caudal. Ventrals reaching or surpassing anus. 

 Pectorals far distant from ventrals. Caudal slightly emarginate, 

 lobes subequal. Scales with a median rather strong keel, some- 

 times with one or two pairs more of weaker ones. Space 

 between pectorals naked, ventral surface otherwise covered 

 with very small scales. Fifteen pharyngeal teeth. Colour in 

 alcohol brown, clouded with large distinct irregular dorsal blot- 

 ches or areas of deep brown, a large one between dorsal and 

 ventrals. Ventral surface a little paler brown than upper surface. 

 A brown streak from tip of snout to eye, and continued 

 behind it up to occiput, an other streak downward across 

 side of head. These streaks all with narrow pale brownish 

 margins. Dorsal and anal brownish- white clouded with dull 

 blackish or blackish-brown. Anal similar, also pectorals and ven- 

 trals, though all these fins have more white and the dark colours 

 more diffuse. Length 125 mm. [Type of the species in the 

 Leyden Museum seen by us]. 



Nomen indig. : Ketapang (Bongan), Tesiot (Howong), 

 Fidjan (Bluu). 



Habitat: Borneo (rivers Raun and Bongan, system of 

 Upper Kapuas, rivers Bluu and Howong, system of Mahakam 

 river, Baram river !). 



Note: We have seen the specimens in the British Museum 

 described by BOULENGER as Homaloptera belineata Blyth. They 

 belong, after our opinion, also on account of their striking 

 colour, not to //. bilineata Blyth from continental Asia but to 

 the present species.
