TION. 



Descrip- x HE head is flat and tumid on each side ; the 

 body taper. The pectoral fins placed unusually 

 high. It has only one dorsal fin ; placed low, 

 or near the tail ; the tail is even at the end ; the 

 color of the head and body is of a fine pink 

 and white in minute spots ; the mouth small ; 

 the teeth small and regular; on each side of 

 the engine of adherence on the belly, behind 

 the pectoral fin, is a purple spot, surrounded 

 by a ring of white. When young, it is of a 

 green color, minutely speckled with blue, and 

 without pectoral spots ; in this state it is propor- 

 tionally longer, and differs a little in the shape 

 of the fins. The eyes are considerably promi- 

 nent, capable of very considerable motion, inde- 

 pendent of each other, and revolve within a 

 fixed transparent sphere, which protects those 

 delicate organs. It rarely exceeds an inch and 

 a half in length.
