DE. GtiNTHBE ON THE FISHES OF CENTRAL AMERICA. 44'7 



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. Cossyj)hus pihlcheUus (Poey) is perhaps identical with it. 



14.3. Platyglossus dispilus. (Plate LXXIV. fig. 1.) 

 Gunth. Proc. Zool. Soc. 1864., p. 25. 



D. •^. 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, 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 5^ inches long. 



144. PsBUDOJULis NOTOSPiLUS. (Plate LXVI. fig. 2.) 

 Gunth. Proc. Zool. Soc. 1864, p. 26. 



D. n- A. ^. L. lat. 25. L. transv. ^. 



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.
