of the Island of Trinidad, W. I. 425 



Stevardia albipinnis, Gill. 



Body subfusiform, elongated, with the dorsal outline slightly 

 arched, and the abdominal outline, as far as the termination of 

 the anal, convex. The head, from the snout to the end of the 

 opercular spine, bears a proportion to the entire length, inclu- 

 sive of the caudal, of little less than one to five and a third, 

 and its length is considerably less than the greatest height of 

 the body. The diameters of the eyes are about three-tenths of 

 the length of the head ; they are separated from each other by 

 a space exceeding one of those diameters, and their distance 

 from the snout is less than a diameter. The dorsal commences 

 on the posterior half of the body, above the seventh or eighth 

 ray of the anal, and is about a third higher than long. The 

 lateral line runs through about forty scales.
