equals the width of the interorbital space and is two-sevenths 

 of the length of the head. The groove for the processes of the 

 intermaxillaries is entirely scaleles, and extends beyond the 

 front margin of the eye. The second dorsal spine is conside- 

 rably longer than the third, its length in ad alt speeimens being 

 more than one half of the height of the body; in half-grown 

 specimens it is scarcely longer than the third and half as high 

 as the body. The scaly sheath of the dorsal fin is moderately 

 developed The second anal spine is stronger and a little lon- 

 ger than the third, its length being more than one-half of the 

 length of the second dorsal spine. There are four series of sca- 

 les between the highest point of the lateral line and the dor-
