EPHIPPIDiE. 



119. Chaetodipterus faber (Bronssonet). 



Apparently uot common ; a single young specimen obtained. 



CHiETODONTIDiE. 



120. Pomacanthus aureus (Bloch). Black Anyel. 



Eather common ; frequently taken with spear or book, not valued as 

 a food -fish. 



Adult specimens are grayish without tinge of yellow ; the center of 

 each scale blackish, the edge pearly gray. Head and vertical fins dusky 

 gray, their tips blackish ; a narrow yellowish bar near tip of caudal, fol- 

 lowed by a dark streak; the tip of the fin whitish. Pectoral yellowish^ 

 especially its inner side and its basal half, its tip translucent. Lower 

 jaw pale flesh-color. Ventrals brown, yellowish at tip. 



Younger specimens have a whitish cross-bar on the anterior part of 

 body, behind which are sometimes still others. 



There is no doubt of the distinctness of this species from P. arcuatus, 

 as has already been shown bj' Bleeker, Poey, and Liitken, P. arcuatus 

 has ten dorsal spines, smaller scales and yellow cross-bands, and is a& 

 yet unknown from the coast of the United States. 



121. Holacanthus ciliaris (Linuieus). Yellow Angel. 



Kather common, the young abundant among the rocks ; the adult 

 often taken with the spear. Not much valued as a food-fish, probably 

 because of some prejudice, as the flesh is said to be very good. 



Color in life, yellowish brown on sides, each scale with a darker or 

 orange spot. Back above, shaded with violet, which grows brighter 

 above and merges into intense sky-blue along the edges of the spinous 

 dorsal and on the region before the dorsal ; scales of dorsal region with 

 brown spots like those on the sides. Head paler, the upper lip yellow- 

 ish ; lower jaw reddish. Spines of preopercle and edge of opercle very 

 bright sky-blue. Iris yellow, marked above and below by blue. Top 

 of head bluish green. Breast sky-bhie, paler anteriorly, the color fad- 

 ing before the vent. Pectoral sky-blue at base, then broadly golden, its 

 edge pale ; axil and inner side of pectoral golden. Ventrals golden. 

 Blue margin of dorsal edged below by dull orange, its posterior edge and 

 produced lobe golden yellow. Cadual colored like body, its edge broadly 

 gohlen-yellow. Anal colored like soft dorsal. Traces of a brownish 

 spot, surrounded with bhie at the nape. 



There seenis to be no sutiicient reason for setting aside the name 

 ciliaris for this species in favor of the later parrce of Bloch. It is true 

 that Liunajus confounded other species with his ciliaris, but the species 

 which he seems especially to have had in mind is apparently the 

 present one.
