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

 from E. fuscus in tlie more elongate body, {adtistus, scorched.)

1962. EUPOMACENTRUS FUSCUS (Ciivlcr & Valenciennes). 



(Maria Molle.) 



Head 3|; depth 2 to 2^ without caudal ; eye 3 iu 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 ej'es; maxillary 

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

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

 and weak, about 8 on lower jiart 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 (4J inches) have 

 shorter ventrals, more proiuineut 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 

 in 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 l)lue spots. It seems to correspond 

 to Pomacentrits atroci/aneus, which species we can not separate from Eiipo- 

 macentrus fuscus. (fuscus, dusky.)

19«3. EUPOMACEXT/RUS DIEXC.EUS, Jordan & Paitter. 



Head3t; depth 2; eye 3f in head; D. XII, 15; A. II, 13; scales 4-28-9. 

 Body elliptical, the dorsal and ventral outlines about equally curved; 

 snout short, not projecting; maxillary reaching vertical from anterior 



* The following is the substance of the original description of this species : Depth 2^ in 

 total with caudal (about IJ without). D. XII, 15 ; A. II, 13; P. 19. Interorbital ring con- 

 vex; upper profile of head arched; suborbital ring, excepting the first bone, dentate; 

 ventral produced, its filamentous ray not reaching the anal; caudal eiuarginate with 

 rounded lobes. Color brown, with vertical bars extending downward and somewhat for- 

 ward, corresponding to the edgings of the scales; fins all brown; tlie pectoral blackish; 

 a few faint pale spots on the suborbital ring, and on the dorsal and anal fins; a black 

 spot ou back of tail and one in axil of pectoral. Co.ist of Mexico. (Troschel.) 



i Pomacentrus atrocyaneus, Voey. Form rather more slender than in Pomacentrus oto- 

 phorus, its height 3 in total length, the head 4J ; eye 3i in head ; maxillary reaching front 

 of the eye; blackish blue, with many blue spots below the eye and on the cheeks, and 

 sometinies on the back; upper lobe of the caudal a little yellowish ; a large, black point at 

 the base of the pectoral above. Length 100 mm. Cuba (Poey). (aicr, black; (cuafeos, blue).
