but distinct. Colours, greyish, becoming dirty white along the abdomen. A 
dark lateral band extends from the eye to the tail ; along its first half are 
three black spots, whilst the whole extent of the back is irregularly lineated. 
Fins, yellow. Dorsal with four black bands. Caudal with three bands and 
a dark margin. A black mark at the base of the tail, with a smaller one 
above and another below it. 
Mob. — Madras. 
B. Without an erectile spine near the orbit. 
Genus. 9. Nemacheiiiis, v. Mass. 
Acnura and Acourus, Swains. 
Acanthocobitis, Peters. 
Dody elongated. Dorsal profile nearly horizontal. Darbels eight or 
six, when the former number is present, the extra pair belongs to the 
posterior nostril, none on the mandibles. No spine on the head. Dorsal 
fin of moderate length, or short, situated opposite the ventrals. 
This genus has been subdivided into those species which have upwards 
of twelve dorsal rays, (Acanthocobitis), and those with less than twelve. As 
this arbitrary division is not a natural one, it is not adopted here. Another 
subdivision has been instituted into those in which the tail is forked, and 
those in which it is entire. The genus may, however, be subdivided into 
those with eight and those with six barbels.
