head, and rather less than one-fourth of the total (without caudal). 

 In the female the origin of the dorsal fin is nearer to the extremity 

 of the caudal, and opposite to the third or fourth anal ray ; in the 

 male it is nearer to the extremity of the snout. Anal process of the 

 male nearly twice as long as the head, vnth recurved spines, and a 

 clasper at its extremity. Pectoral and ventral fins short. Free 

 portion of the tail moderately deep. Greenish, reticulated with 

 hrown, with silvery cross bands. A black spot at the posterior part 

 of the base of the dorsal. {Poey.)

The height of the body is somewhat more than the length of the 

 head, which is contained thrice and three-fourths in the total (with- 

 out caudal) ; the diameter of the eye is more than the length of the 

 snout, two-fifths of that of the head, and three-fourths of the width 

 of the interorbital space, which is nearly flat. In the female the 

 origin of the dorsal fin is nearer to the extremity of the snout than 

 to that of the caudal, and opposite to the second ray of the anal fin. 

 Caudal fin of moderate size, as long as the head, rounded behind. 

 The free portion of the taU is somewhat elongate, the length of the 

 base of the anal being two-fifths of its distance from the caudal. 

 Pectoral fin shorter than the head, and extending somewhat beyond 

 the root of the ventral fins, which reach the vent. Reddish olive 

 above, sometimes with indistinct silvery cross bars on the side of the 

 tail ; an indistinct dark band along the middle of the side, and, above 

 it two or three reticulated black spots, their number and situation 

 bein" variable, even on both sides of the same individual ; a black 

 line along the lower and upper margins of the tail ; a blackish blotch 

 on the posterior rays of the dorsal fin.

 The height of the body is somewhat more than the length of the 

 head, which is one-fourth of the total (\vithout caudal) ; the diameter 

 of the eye is more than the length of the snout, one-third of that of 

 the head, and two-thirds of the width of the interorbital space, which 

 is quite flat. In the female the origin of the dorsal fin is nearer to 

 the extremity of the snout than to that of the caudal, and opposite 

 to the second ray of the anal. Caudal fin large, longer than the 

 head, rounded behind ; the free portion of the tail is somewhat elon- 

 gate, the length of the base of the anal being less than one-third of 

 its distance from the caudal. Scales on the belly comparatively large, 

 as large as those on the tail. Pectoral fin shorter than the head, and 

 extending beyond the root of the ventral fins, which reach the vent.
