lubricous. 
The head, large, broad, depressed; the crown rough; the rostrum obtuse, projecting over the mouth. The 
mouth, lips, jaws, teeth, and palate, as before described in No. CLXVI. The tongue fleshy, thick, obtuse, 
smooth, fixed. The eyes oval, large; the nostrils also large, and between them is a small mucous aperture. 
The branchial membrane has four rays. There is a cirrus at the corner of the mouth on each side, and four 
shorter from the lower jaw. The lateral line at first bends downward, but from above the ventral fin runs 
straight to the tail: a second line rising under it, (as in No. CLXVII.) forms an inverted arch, which terminates 
at the anal, not the ventral, fin. The anus nearer the tail than the head. 
Th eji?is. The first dorsal armed with a strong spine, serrated on both sides; the ramous rays acuminate 
above; the spurious adipose fin distant, opposite to the anal. The pectoral very low, armed also with a strong, 
serrated spine; the ventral remote, short; the rays of the anal declining from its rise; the caudal fin falcate, 
the upper lobe considerably longer than the under.

REMARKS. 
This species is abundant at Vizagapatam, but eaten only by the lower class. It rarely exceeds one foot in 
length. The double lateral line in this and in No. CLXVII. is remarkable.
