of the Island of Trinidad^ W. I. 57 



Sub-genus. 



PCECILURICHTHYS, GiLL. 



Lateral line continued to the caudal fin. 



PoBcilurichthys Brevoortii, Gill. 



Vernacular: Sardine. 



Body oval, with the head forming little more than one-fifth 

 of the entire length, inclusive of the caudal fin. The eyes are 

 large, their width being slightly less than a third of the head's 

 length ; the distance between their anterior borders and the 

 snout is more than two-thirds of one of their diameters, and 

 twice that space intervenes between them. The dorsal com- 

 mences at a distance from the snout equal to double the length 

 of the head ; the greatest height of the body is equal to one- 

 third of the entire length. The ventrals do not reach the anal ; 

 tha tips of the pectorals barely extend to the bases of the ven- 

 trals. There are no markings oai the operculum. The body is 

 crossed by fifteen rows of scales.

The back and npper part of the body are of a pale yellowish 

 green color, which is separated from the lighter hue of the 

 lower portion, by an obscure silvery band, extending from the 

 upper angle of the operculum to the caudal fin. There is a very 

 distinct black spot on each shoulder, a little above the oblique 

 portion of the lateral line, and another on the tail, which often 

 advances along the middle rays of the caudal to the margin of 

 that fin, terminating in a point ; the anterior portions of the 

 pectorals, and the anal, are bright orange. The opercular bones 

 are silvery. 



This is the largest of the Trinidad species of this genus, and
