226 NEW SPECIES OF FISHES. (May. 



subtriangiilar, lengthened to a point before, thick at base, 

 flexible at their posterior margin, and distinguished from 

 the body by a slight round potch: the outer margin has 

 curved sharp points; abdommal fins lanceolate, straight, 

 narrow, bordering the body, and ending in an appendage, 

 called by Bloch hands, in the males: a notch distin- 

 guishes the appendage from the fm. The two doisals sub- 

 triangular, between the ventral fins and end of the tail; 

 caudal elevated, notched, lobes pointed, the lower one 

 longest. 



Colour of tlie head, back, fins and tail a bluish ash 

 gray, with reddish tints upon the head and margin of the 

 fins; abdomen white; but there is a remarkable reddish 

 spot on the throat, another on the abdomen, and another 

 behind the vent, extending to the end of the tail. Tlie 

 pectorals and ventrals are in like manner bordered with 

 large and irregular bands of the same colour. 



My observations on this species are derived from 

 three individuals, perfectly alike; and the drawing was 

 made from one which Mr. Titian Peale kindly put into 

 my hands for examination, before preparing it for the 

 museum. Another was presented to the Academy of 

 Natural Sciences by Mr. Lownes, a member; and the 

 third exists in a private collection. The general length 

 is from three to four feet. 



This fish wholly differs from the European species, of 

 which 1 made a drawing, from a fresh specimen, in 1813, 

 at Houen; it was also a male. 



I have dedicated this fine species to M. Dunaeril, in 

 testimony of my remembrance and esteem.
