DISCUSSION OF SPECIES AM) TIN'.IK DISTRIBUTION. 



373 



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

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



Tin- vent is situated at a point equidistant from snout and tip of caudal, under the 19th 



ray of second dorsal tin. The anal tin 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 sec 1 dorsal. It 



has a considerable depression in its middle outline. The last lays of dorsal and anal are of 

 equal length and are directly opposite each other. 



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

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

 ing caudal. 



Pectorals narrow, inserted under the base of fust 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 speeimeu, in which it is 

 unmutilated, nearly as long as the head. 



Radial formula: D. 4, 53; A. 40; C. 5, 20 or 21, 5; P. 1, 19; V. 6. 



Color, deep violet or blue.
