The length of the fish was 19 inches, and breadth 7-|. 

 The dorsal fin commences nearly parallel to the vent ; the first thirteen 

 rays are bony, round, and spinous ; the first is the shortest, the rest 

 gradually longer, all united in the common membrane. The soft 

 rays increase in length from the first to the sixth, which is the long- 

 est, the rest decrease gradually to the last, which is shortest ; this 

 fin ends about an inch before the origin of the tail. 

 The pectoral fins are nearly on a line with the middle of the gill- 

 aperture, acuminated above, the longest ray 3 J inches long ; the base 

 of these fins a dull black. 

 The ventral fins commence on a line with the posterior ray of the pec- 

 torals. The first ray short, bony, and spinous. The second ray is 

 very long, reaching to the end of the tail, rounded, and tapering to 

 a hair-like point ; their proportions are as follow : — 



The length of the first ray 1 inch 



Second ditto 12 



Third ditto 1^ 



Fourth and Fifth .... 1 



Sixth Of 



The anal fin commences immediately behind the vent ; it resembles 

 the dorsal, but terminates closer to the caudal base, to which 

 it is somewhat united by a naked continuation of the common 

 membrane. 

 The caudal fin is rounded, very scaly at the base, broad and strong.
