324 FISHES FROM BRAZIL JORDAN. 



Specimens from Key West belougiug to leucostictus are slenderer than 

 the young offnscus, the blue clots on head forming stripes on head and 

 on side of snout 5 the dorsal ocellus is higlier on the fin ; there is no 

 ocellus on the caudal peduncle; the i)ectoral is shorter than in P. cau- 

 dalis. A white spot on base of last ray of anal. Pomacentrus atrocy- 

 aneus and analis of Poey seem to be identical with P. leucostictus. 



The specimens from Key West, identified as the male of ohscuratus, 

 are probably adults of leucostictus, from which they differ in daiker 

 color and greater depth. 



Those called the female of ohscuratus are probably different from 

 leucostictus and are Pomacentrus ohscuratus. In these the profile of the 

 head is very blunt and convex in every direction. The color is very 

 dark and th re is no spot except a few blue ones on the head and sides 

 and a dark shade on the base of the pectoral. The body is deeper than 

 in the adult offuscus (depth, 2i in lengtli in fuscus ; 2 in ohscuratus). 



82. Pomacentrus caudalis Poey. 



One of the specimens from Bahia corresponds with Poey's caudalis 

 and probably does not belong to Pomacentrus fuscus. It is very slightly 

 more elongate, its coloration is largely yellow, the fins not black ; blue 

 points on head, base of caudal, and anal ; axil dark ; a black blotch on 

 dorsal and one 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 bisb anal ray. Perhaps caudalis also is one of the 

 protean forms assunn d hj fuscus, and it may be that the Pomacentrus 

 pictus of Oastelnau, brown, with the caudal mostly yellow, is one of the 

 forms of the same fish. 



83. Chromis marginatus (Castelnau). 



Several specimens. Dorsal spines, 12 ; scales, 3-30-10 ; gill-rakers 

 numerous, long, and slender; pectoral a little longer than head, not, 

 quite reaching anal ; upper lobe of caudal longest, the fins deeply 

 forked ; color, bluish olive, a black spot within axil and on base of 

 pectoral ; dorsal black, except the last rays ; each lobe of the pointed 

 caudal black, the middle of the fin pale; traces of three lengthwise 

 stripes of yellow on the body. 



This species is close to Furcaria cyanea Poey, but this species has 

 blue spots on the scales. The Pacific coast species, Chromis atrilohatus 

 Gill, is quite distinct from marginatus.
