in the total length (without caudal), the length of the head three 
and a half times. The scales are of moderate size, regularly arranged 
and ciliated on the blind side of the body as well as on the coloured : 
they cover nearly the whole head, -even the maxillary, leaving only 
the foremost part of the snout uncovered. The eyes are two-sevenths 
of the length of the head, and separated from each other by a high 
sharp, <>^-shaped ridge. Each fin-ray is accompanied by a series of 
minute rough scales. Lateral line with a sub-semicircular curve 
above the pectoral fin. Lower jaw prominent; the length of the 
maxillary is two-fifths of that of the head, the bone extending 
beyond the front margin of the eye, but not reaching to below its 
middle. Teeth on the head of the vomer extremely small. Lower 
eye a little in advance of the upper. The dorsal fin commences in 
front of the eye, and is rather low ; the hindmost very small rays are 
inserted on the blind side of the body. Ventral fins separated from 
the anal. The pectoral fin of the coloured side is rather small, but 
larger than that of the blind side ; it consists of eight rays, of which 
the fourth is the longest, extending beyond the bent portion of the 
lateral line. Brownish, marbled with darker ; a large blotch at the 
commencement of the straight portion of the lateral line, and a 
transverse band on the tail behind the dorsal and anal fins, are the 
most conspicuous markings. The rays of the vertical fins are 
irregularly annulated with blackish-brown.
