D. 7\11. A.9. The head and the trunk are naked ;, the tail is 
covered with small scales ; head depressed, broader than high, flat 
above, its length being two-sevenths of the total. Snout rather ob- 
tuse, longer than the eye, with the lower jaw somewhat prominent ; 
the cleft of the mouth extends to below the anterior margin of the 
orbit. Teeth in the upper jaw inanarrow band ; the lower has four 
somewhat larger and recurved teeth in front, the others appear to 
form a single series; palate toothless. None of the fin-rays are pro- 
longed ; the pectoral does not quite extend to the origin of the second 
dorsal; ventral much shorter than pectoral, its imner ray is the 
longest, the others gradually decreasing in length outwards ; caudal 
fin rounded. Brown, with numerous well-defined white cross stripes 
on the head as well as on the body; vertical fins black. 
Although there is only a single example, 20 lines long, in the col- 
lection, the characters of this species are so well marked that I do 
not hesitate to describe it.

the body is nearly equal to the length of the head, and contained 
five times and a half or five times and a third in the total length 
(without caudal). The snout is short, not longer than the diameter 
of the eye, and the cleft of the mouth does not extend backwards to 
below the anterior margin of the eye. The anterior dorsal is com- 
posed of short, feeble spines, and its origin is opposite to the fourth 
or fifth anal ray. The pectoral fin is much longer than the head. 
The silvery streak occupies the adjoining halves of the third and 
fourth series of scales. 
Two specimens, 6 inches long, were in the collection.

D.6. A.5. C.8-9. P.17. A vertical fold of the skin along 
the lower half of the base of the pectoral; the coracoid is scarcely 
below the level of the upper margin of the pectoral. The distance 
of the origin of the dorsal fin from the caudal is contained twice and
