Head 31^ to 3|; depth 2f (adult) to 3^ (young). D.9; A. 6to8; 8cales24to 

 26-9. Origin of dorsal midway between base of caudal and front of eye, and 

 over tenth scale of lateral line; fins moderate, longest ray of dorsal 

 about as long as head without snout; caudal scaly at base; caudal 

 peduncle compressed and deep. Color uniform olive, the young with 

 faint, dark cross shades; caudal with a few black spots; dorsal with 

 numerous round, black spots in both sexes. Allied to Pucilia dovii, but 

 with deeper body and larger scales. Length of adult 2 inches. 



Fresh specimens recently obtained by the Hopkins Expedition from the 

 Rio Presidio are described as follows: Head 3^; depth 3*^. D. 9; A. 6; 

 scales 2(5-9. Eye equal to snout, 3 in head; interorbital width 2. Pecto- 

 ral li in head ; caudal 1 in head ; longest dorsal ray in males If in head, 

 in feuiales If. Body deep and compressed, the form as in Adinia, the 

 straight anterior profile rising considerably to front of dorsal. Dorsal 

 small, even in the male, inserted over or somewhat before anal, much 

 behind anal in female. Teeth in two series, well separated, the inner series 

 smaller and more close-set, not trifid; caudal peduncle very deep, the fin 

 broad. Males larger than females, equally numerous, and with liigher fins, 

 as in MoUienesia. Color of males green, with a pale-blue spot on each 



* In the tiguro of Bloch & SchDeider the body is represented as marked by broad cross bands
