DISCUSSION OF SPECIES AND THEIR DIvSTRIBUTION. 



373 



snout; its greatest height, which is in tho posterior fourth of its length (near the 40th ray), 

 is contained about six or seven times in the length of its base. 



The vent is situated at a point equidistant from snout and tip of caudal, under the littli 

 ray of second dorsal tin. The anal fin is inserted at a distance behind it equal to length of 

 second anal ray. Its length of base is slightly more than half that of second dorsal. It 

 has a considerable depression in its middle outline. The last rays of d(u-sal and anal are of 

 equal length and are directly opposite each other. 



The caudal seems to be somewhat rounded. The length of the middle rays contained 

 more than 9 times in total length without caudal, and more than 10 times in length includ- 

 ing caudal. 



Pectorals narrow, inserted under the base of first dorsal. In the smaller specimen they 

 reach to the perpendicular from the ninth ray of the second dorsal, in length equaling the 

 greatest height of the body. 



Ventrals inserted at a distance from tip of snout equal to half the length of anal base; 

 the second ray nearly twice as long as the first, and in the smaller specimen, in which it is 

 unmutilated, nearly as long as the head.
