158. Peprilus medius {reicrs). 



The Panama record of this species (Jordan, 1885, p. 375) needs verification. 

 The specimens obtained may have belonged to one of the forms above recorded, 

 both of which were at that time unknown. Only the type of P. medius is now 

 extant. 



Family CHEILODIPTEIIID.E. 

 159. Apogon dovii Giiniher. 



Abundant about the rocky islands in Panama Bay. 



The species varies in color from light to dark red, with much or little black 

 pigment. The caudal may be translucent or blackish, the soft dorsal is translucent, 

 or may be tipped with black, or may be largely black with only the posterior rays 

 whitish. The anal and ventral fins may also be translucent, or with the terminal 

 portions more or less largely black. Young specimens are marked with a very con- 

 spicuous round or elliptical black spot on the end of the caudal peduncle, and a rather 

 poorly-defined dusky streak around the snout and across the opercle. The streak 

 wholly disappears and the caudal spot becomes very faint and diffuse with age.
