blue, closer set above; those before eye and on snout oblong, stripe-like; 

 these spots appear black in life, but in spirits they become intense sky- 

 blue, and ultimately fade to whitish; each scale of back above lateral line 

 anteriorly with a vertically oblong stripe of dark blue; behind and below 

 these, many scales have each a round point of deep violet; one row of 

 these on upper edge of caudal peduncle on each side, and three partial 

 series below lateral line ; dorsal bluish-black, each scale with a blue point ; 

 last rays of soft dorsal yellow; a black point at base of last ray; a large 

 blackish blotch on middle of first soft rays in the young; spinous dorsal 

 with a marginal pale band made of 2 narrow stripes of bluish, and 2 of 

 dull orange; anal golden yellow, its edge dusky, traces of a pale spot at 

 base of last ray; pectoral yellow, a conspicuous blue spot at base above; 

 ventrals yellow, tinged with bluish; a blackish blotch on middle of base 

 of lower jaw. About rocks and reefs in clear, rather deep water; not 

 rare. West Indies north to the Snapper Banks of west Florida; common; 

 a handsome fish, apparently distinct from E. fuscus j but not always easily 

 distinguished. 



A specimen in good condition from Pensacola is thus described (under 

 the name Pomacentrus caudalts): Head 3; depth 2J-. D. XII, 14; A. II, 

 13; scales 4-29-9. Form oblong-ovate; the anterior profile moderately 

 convex. Preorbital and preopercle well serrated. Teeth moderate, entire. 

 Soft parts of dorsal and anal rather high. Upper parts dusky ; the greater 

 part of each scale of a light grayish-blue; lower parts bright yellow, with 

 some blue spots on the scales ; top and sides of head similarly marked with 

 bluish spots on the scales; a jet-black, ink-like spot, ocellated with blue 

 on the back of the tail; dorsal fin colored like the back ; the posterior soft 

 rays abruptly yellow; caudal fin bright yellow, lower fins chiefly yellow. 



We have also the following notes on a specimen from Bahia, also called 

 "caudalis;" it is very slightly more elongate than E. fuscus. Its colora- 

 tion is largely yellow, the fins not black ; blue points on head, base of 

 caudal and anal ; axil dark ; a black blotch on dorsal and 1 on back of 

 caudal peduncle larger than in the young of fuscus and less ocellate. The 

 forehead is less decurved, and there is a white dot at base of last anal ray. 

 Perhaps caudalis (=leucostictus) also is one of the protean forms assumed 

 by fuscus, and it may be that Pomacentrus pictus of Castelnau, brown, with 

 the caudal mostly yellow, is one of the forms of the same fish.

"This species agrees with P. fuscus of Cuvier et Valenciennes; it distinguishes itself, 

 however, by numerous white dots, which are especially abundant beneath the dorsal and 

 above the anal fin, where one is placed on each scale." (Miiiler & Troschel.) 



Tn the younger individuals the white dots are much more distinct, and this may have 

 induced the fishermen to give them the name of Beau Gregory; the full-grown specimen 

 is called Black Pilot.
