This species in the shape of the body and head, and the structure of the mouth and jaws, agrees with the last 
described: they differ in the following respects. The cheeks are squamous; the body without scales, trans¬ 
parent; the branchial membrane has only seven rays; and the caudal fin is round, with a small black spot 
towards the root. The situation of the other fins, the lateral line, and the second line near the belly, are as 
described in the last; but the dorsal and anal fins are broader and shorter. 
The colour whitish, clear, transparent. Along the back near the ridge, are three black lines, from the oper- 
cula to the dorsal fin. The fins are glassy more or less light colour; the tail yellowish-green, with a black 
spot, as already mentioned.

The body long, roundish, compressed, somewhat quadrate; covered with large, smooth, tenacious scales. 
The head not so broad as the body, without scales, compressed on the sides, plane above. The mouth 
roundish, horizontal; no lips. The upper jaw short, under the rostrum: the under is extended into a long 
bony sword-form process, depressed above, grooved both above and below. The teeth in both jaws small, 
linear, close, without order. Tongue oblong, obtuse, smooth, loose. The palate smooth also, but the fauces 
rough. Eyes high, middle size, round, iris silvery. The opercula without scales. 
The trunk. The lateral line supreme, straight, declining very gently; the other ventral line conspicuous, as 
in the two former, but bends more downwards, and the belly being more convex, is consequently less parallel 
to the lateral line. The anus, as in the others, remote.
