cc. Lower posterior half of body unlike anterior part, being more or less abruptly bright-yellow; caudal fin bright- 
yellow; usually a blue spot at base of last ray of anal.

jj. Region below lateral line with few blue spots or none. 
h. Back with two round dusky spots on each side flaviventa

180. Eupomacentrus fuscus (Cuvier & Valenciennes) . Brown Cockeye Pilot; Maria Molle 
(Plate 27.) 
Head 3.5; depth 2.5; eye 3.4; snout 3.5; maxillary 3; I>. xn, 15; A. ii, 13; scales 2-28-9. Body 
compressed, anterior profile steep and evenly convex; dorsal and ventral outlines similar; mouth 
moderate, little oblique; maxillary reaching anterior border of orbit; jaws equal; teeth in a single series 
in each jaw, incisor-like, and closely placed; preopercle and preorbital serrate; gillrakers small, weak; 
scales large, ctenoid, reduced in size on head; snout, opercles, and cheek scaled; lateral line concurrent 
with back to below middle of soft dorsal, where it ceases. Fins rather large; longest dorsal spine about 
2 in head, dorsal rays elevated, longest 1.2 in head; second anal spine 2 in head; soft anal similar to 
soft dorsal; caudal forked, lobes equal, about 1 in head; pectoral rather long, reaching vent; ventrals 
long and pointed, passing vent. 
Color, dark-blue above, lighter on the sides and under parts; side of head and body with some 
yellowish, under parts with purple tinge; in some specimens the general color is dark-brown or nearly 
black; edges of scales dark, forming narrow dark vertical bands, but in most specimens these are 
entirely absent; dorsal and anal fins dark-bluish or olivaceous at base, the margin brighter blue; caudal 
dusky or pale, usually with some yellow at base; pectoral and ventrals greenish-olivaceous, no black 
spot at base of pectoral, no dorsal ocellus and no white spot at base of last anal ray; no bluish or whitish 
spots on head or body. 
This species may be distinct from E. analis, or the latter may be simply an individual color varia- 
tion from the typical form. The specimens which we refer to E. fuscus were obtained by us at 
San Juan, Aguadilla, and Ponce, and by Mr. Gray at San Geronimo. 
Found in the West Indies south to Brazil and north to Ivey West. The least common of the thr< e 
species of Eupomacentrus which we recognize from Porto Rico.

Head 3.2 to 3.5; depth 2 to 2.4; snout 3.2 to 3.5; eye 3.2 to 3.5; maxillary 3.2 to 3.75; mandible 
3.75 to 4.25; interorbital 3.25 to 3.66; preorbital 7; scales 3-28-8; I). xii, 15; A. ii, 13. Body rather 
deep, strongly compressed, anterior profile steep and evenly convex; interorbital area strongly convex; 
eye usually a little greater than snout; mouth small, slightly oblique, jaws equal; teeth in single series, 
incisor-like and close-set; maxillary scarcely reaching vertical of anterior part of orbit; gillrakers 
slender, weak, and short, length less than diameter of pupil; preopercle strongly serrate; preorbital 
also serrate, but less distinctly so; scales large, firm, and strongly ctenoid; lateral line beginning at the 
upper edge of opercular opening running parallel with dorsal outline to beneath middle of base of 
soft dorsal, where it abruptly terminates; top of head and snout densely scaled, scales smaller than on 
side; opercle and preopercle scaled; chin naked; bases of dorsal and anal fins densely scaled; mem- 
branes of caudal fin covered with very small scales; dorsal spines strong and sharp, length of longest 
1.8 to 2 in head; soft dorsal with its middle rays elevated, their length 1.2 to 1.4 in head; first anal 
spine very short, second much longer and stronger, its length 2 in head; soft anal similar to soft dorsal, 
its longest rays about 1.25 in head; pectoral broad, short, scarcely reaching Vent, length about 1.2 in 
head; ventral longer, tips of outer rays passing vent, about equal to length of head; caudal forked, 
upper lobe the longer, usually somewhat longer than head. 
Color in life very variable; back and upper part of side usually dark-blue or bluish, becoming 
somewhat paler on lower part of side and belly; head dark-blue; sometimes body is a dark brown, with 
scarcely any trace of blue; in other specimens the color is a sooty blue-black in life, under parts
