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 rays. 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 
two-thirds in its distance from the snout ; the anal commences below 
the third dorsal ray. A very narrow band of short conical teeth in 
the upper jaw—one of the lateral teeth being somewhat larger than 
the others, recurved, canine-like. The lower jaw with a single series 
of teeth, the anterior being narrow incisors, whilst the outermost on 
each side is distinctly a canine tooth, corresponding to that in the 
upper jaw. Rose-coloured, with dark-rose transverse spots, each 
spot having an edge of deep-red dots. 
Two specimens, 18 inches long, are in the collection. 
21. PLATYGLOSSUS DISPILUS, 2. sp. 
D. 2. A. = L. lat. 28. L. transv. 2/9. The height of the 
body equals the length of the head, and is contained four times and 
one-fourth in the total. Caudal fin rounded, with the lobes very 
slightly produced. Greenish olive, with a roundish black spot edged 
with silvery, on the lateral line, below the fifth and sixth dorsal 
spines; the side of the head with five or six pearl-coloured streaks, 
apart of which are continued on the body, forming a series of round 
spots. An oblong variegated blotch behind the pectoral fin: it is 
composed of three pearl-coloured stripes, enclosing two yellow bands, 
each of which has an undulated purple edge. No spot in the axil of 
the pectoral. A short oblique yellowish streak behind the base of
