Epinepbclns mystaciinis, the cherna de lo alto, is found among 

 the West Indies and south to Brazil, in rather deep water. It reaches 

 about 2 feet in length, but is not abundant enough to be of much com- 

 mercial importance. Colour in life, dull olive-brown above, the body 

 grayish brown, crossed by 8 bands of dark olive-brown, the one on 

 caudal peduncle broadest, darkest on back of tail; a dark line along 

 edge of maxillary, and ^ dirk bands across cheek; mouth bluish inside. 

 E. iinalogns, the cabrilla pinta, is a west coast species, known from 

 P. mama and San Salvador. It is not rare, reaches a foot or more in 

 length, and in life is orange-brown on an olivaceous ground, as in E. 

 </,/.s'//.v'<>///\, which this species strongly resembles; no distinct dark 

 edgings to the vertical fins.
