"The height of the body is contained 3 to 3^ times in the total length 

 without caudal, the length of the head 3^ to 3J times ; the diameter of 

 the eye excels the length of the snout and is contained 3 times in the 

 length of the head and equals the width of the interorbital space; the 

 groove for the i)rccesses of the intermaxillaries is naked and extends to 

 the vertical through the anterior third of the eye ; the free portion of 

 the tail is longer than high ; the least height of tail equals the length of 

 the 6th dorsal spine ; the 3rd dorsal spine is the longest, its length being 

 contained twice in the height of the body and equals the length of the 

 head without the postorbital portion ; the last dorsal spine equals in 

 length the 2d anal, and about equals the length of the snout, and is about 

 I as long as the 3d ; the first dorsal ray is fully 1^ times as long as the 

 1st dorsal spine ; the 2d anal spine is stronger and shorter than the 3rd, 

 its length being contained 3| in the length of the head ; the 3d anal 

 spine is contained 3^ times in the length of Ihe head ; the caudal is 

 forked, its length slightly less than the length of the head, and very 

 little greater than the length of the pectoral ; the pectoral reaches to 

 the perpendicular through the origin of the soft dorsal. The ventral is 

 half as long as the head ; the vent is under the 2d ray of the soft dor-
