(Poey ; description of P. obscuratus) ; a doubtful species, perhaps differing 

 from E. fuscus in the more elongate body, (adustus, scorched.)

(MARIA MOLLB.) 



Head 3J; depth 2 to 2 without caudal; eye 3 in head; snout 3. D. XII, 

 13 to 15; A. II, 13; scales 3-28 to 30-9. Body compressed, dorsal and ven- 

 tral outlines similar, profile convex, more so between the eyes ; maxillary 

 scarcely reaching vertical from front of orbit; posterior margin of preop- 

 ercle and inferior margin of suborbital ring serrulated. Gill rakers small 

 and weak, about 8 on lower part of anterior arch ; tips of pectorals scarcely 

 reaching the vent; ventrals reaching to or slightly past vent; head with 

 very few, if any, small accessory scales. Older examples (4 inches) have 

 shorter ventrals, more prominent serrations on preopercle, a deeper body 

 and lighter and more uniform color than smaller specimens (3 inches in 

 length). Color dark brown to nearly black, edges of scales darker, form- 

 ing narrow vertical crossbars more distinct in smaller specimens (3 inches 

 iu. length) ; fins all dark brown to black, a black axillary spot, a few obscure 

 white dots on head and about base of anal: no white spot on last anal 

 rays. Very young with an ocellus on dorsal fin, and a dark spot on caudal 

 peduncle behind soft dorsal. In none of our specimens is the caudal yel- 

 low. West Indies and coast of Brazil ; north to Key West, about coral 

 reefs; common and variable; the specimens above described from Bahia. 

 A specimen from Key West has more blue spots. It seems to correspond 

 to Pomacentrus atrocyaneus, which species we can not separate from Eupo- 

 macentr us fuscus. (fuscus , dusky.)
