1566. MYCTEROPERCA MICROLEPIS (Goode & Bean). 

 (Gag; Aguaji'.) 



Head 2f ; depth 3^ ; eye moderate, 6i in head (young). D. XI, 16 to 19 ; 

 A. Ill, 11 ; scales 24-140 to 145-50 to 60, pores 88 to 95. Body compara- 

 tively elongate, compressed, its greatest width 2i in greatest depth. 



* The following is the original description of this species, slightly condensed: Ilead 2.6 in 

 body to base of caudal (3.1 in total); depth 3.6 in body; depth of caudal peduncle 8.8; dorsal 

 XI, 17; anal III, 11; scales very small, crowded, ahout 20-160-40. Body comparatively elongate, 

 compressed. Head long, lower jaw protruding, maxillary extending but slightly beyond the eye 

 in the smaller specimens and not at all in the larger ones; eye 7.2 in head, the iuterorbital 

 space 6 in head. Preopercle slightly emarginate above the angle and on lower limb below the 

 angle; the serra; above the angle very fine, at the angle stronger, the lower limb entire. Nos- 

 trils not very near together. Distance between them 8 in longer diameter of eye; the anterior 

 circular, with a flap; posterior elliptical and not more than twice the diameter of tho anterior. 

 Gill r.akers of anterior arch rather short, the longest about 2 in eye; about 9 developed and 2 

 rudimentary ones on lower branch, one in the angle, 2 well develo])ed on upper branch, with a 

 few others rudimentary. Teeth on lower jaw in about 2 series, laterally strong; on upper jaw 

 several strong teeth intermingled with many small ones; two prominent canines in each jaw. 

 Caudal tin very slightly lunate, the outer rays scarcely longer than inner, 2 in he.id; pectorals 

 reaching beyond the tip of ventrals, 5 in body and 1.9 in head; ventral fin shorter than tho 

 pectoral, 6.25 in the body, its spine 4 in head; the first 3 spines of the dorsal graduated, the first 

 8.8, the second 4.26, the third 3.3, in head; the tenth spine 4, and the eleventh 3.8, in head. 

 The longest soft ray, tho sixth, 2.3 in head; origin of doi-sal a little less than length of he.id 

 from tip of snout; anal spines graduated, the first 14.4, the second 6 4, the thirti 5.2, in head, 

 the flu evenly rounded, the longest soft ray 2.3, and the last 4.8, in head. Color in alcohol, much 

 as in E. bonaci, Poey, brown, with irregular darker mottlings of considerable size, but varying 

 much; belly paler; dorsal and anal fius of the general color of tho body, tlie anal having the 

 lower edge pale, the outer margin not evidently darker; ventrals black with tho tip white; pec- 

 torals paler.
