of the Island of Trinidad, W. I. 419 



the margin of the fin, and is bordered above and below by 

 yellow ; the remainder of the fin is white; the anterior rays of 

 the first dorsal and adipose fin are red. The other fins and the 

 operculum are silvery. There is a humeral spot as in P. Bre- 

 voortii Gill. 



The average length of this species is less than three inches. 

 Its distinctive characters reside in the slender body, and the 

 uniform black band running along the median rays of the caudal 

 fin, and bordered above and beneath with yellow. 



Pcecilurichthys pulclier, Gill. 



Vernacular: Sardine. 



The outline of the body is oval, and including the caudal, is 

 three and two-fifths longer than the height at the dorsal. 

 The head forms three-sixteenth parts of the entire length of 

 the body ; the eyes are very large, their diameters being nearly 

 one-third of the length of the head ; they are separated from 

 each by a space equal to one of their diameters, and by two- 

 thirds of that distance from the snout. The distance of the 

 dorsal from the snout is more than double the length of the 

 head. The ventrals do not extend as far back as the anal.

The body is chiefly of a greenish yellow color, with a silvery 

 band running along the sides ; an obscure humeral blotch is 

 generally perceptible ; at the end of the caudal peduncle there 

 is a black spot, which is bordered above and below by red, or 

 sometimes yellow blotches. The dorsal and anal fins are white, 

 tinted witfi red; on the operculum there are blotches of a 

 bright golden color. 



This species is readily distinguished by its smaller size, which 

 rarely exceeds one inch and a half; by the golden markings 

 on the opercula, which are seen in neither of the preceding
