of the Island of Trinidad., W. 1. 6T 



The dorsal commences at a distance from the snout equal to 

 three lengths of the head ; the length of the base of tbis fin is 

 about three sevenths of that of the longest rays. The base of 

 the anal has a length almost three times as great as the dorsal's, 

 but its longest rays are considerably shorter than those of the 

 latter fin ; the last two or three rays are longer than those 

 which immediately precede them.

The color is nearly similar to that of Stevardia albipinnis. 



Mr. A. II. Riise of the Danish island of St. Thomas, the 

 gentleman to wliom this species has been dedicated, is well 

 known as one of the most active zoologists of the West Indies, 

 and has greatly contributed to our knowledge of the terrestrial 

 MoUusks, and the Echinoderms, by his contributions to Dr. Louis 

 Pfeifi*er, and Dr. A. Lutken. 



Corynopoma Veeelonii, Gill. 



This species resembles in the general shape of the body, and 

 in its size, Stevardia albipinnis, and Corynopoma Hiisei. The 

 head is slightly longer in proportion to the total length, and the 

 eyes are rather smaller, but the chief difference consists in the 

 greater length, and the direction of the claviform prolongation 

 of the operculum ; this appendage, instead of being deflected 

 downwards for its entire length, descends onl}'- at the base, and 

 very soon advances upwards with a curve, and is continued in 

 a nearly straight line, and in a direction towards the anterior 

 portion of the dorsal ; it terminates on , a line with the base of 

 the ventral ; its size is nearly eqnal from its point of curvature 

 to the termination. 



The dorsal commences at nearly the same distance from the 

 snout as in the Corynojpoma Hiisei, and its proportion varies 

 little from those of the latter species, its height being more than 

 double the length of the base. The anal is not quite as long in 

 proportion to the dorsal as in the C. Biisei ; its first and longest
