from Bahia, which I have examined, the larger is without any trace of such a spot; 
whilst the smaller one shows one, of about the size of the scale, on each side of the base 
of the last dorsal ray. 
141. CossypHus PECTORALIS (Gill). 
This species occurs also in the Atlantic, as I have lately received fine examples from 
St. Helena. Cossyphus pulchellus (Poey) is perhaps identical with it.

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, a part 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 each soft dorsal ray; these streaks form a continuous band on the 
spinous portion. Anal fin with two or three whitish lines; caudal with several 
irregular reddish longitudinal bands, which are convergent behind. 
Young specimens are much more plain-coloured ; the black spot on the lateral line, 
however, is very distinct, and there is another at the root of the caudal. 
Capt. Dow’s Panama collection contains a single young specimen; but Mr. Salvin has 
brought others, one, apparently adult, being 53 inches long.

The height of the body is rather less than the length of the head, and contained four 
times and a quarter in the total. Dorsal spines pungent; caudal fin slightly rounded. 
Brownish or yellowish olive; young specimens with a silvery band along each side of 
the trunk, above the pectoral fin. Back with four or five indistinct broad brown cross 
bars; a series of blotches on the dorsal fin corresponds to these cross bands, one of 
them, on the first three dorsal rays, being the largest and most distinct ; it is of a deep 
black colour, and of an ovate form. The corners of the caudal fin are white; ventral 
whitish, with a broad blackish outer margin. 
One adult specimen, 4 inches long, and several young ones were collected by Capt. 
Dow at Panama.
