POIVIACENTRIDAE. 133 



the Jordan and Evermann colloction, seven specimens have dorsal 17, anal 14 

 as we count them. 



The very young have a small white margin on spinous dorsal, becoming 

 progressively but variously narrower in specimens up to three inches long, after 

 which it seems to disappear entirely. This margin is not so evident in the 

 Hawaiian specimens of similar size. This may be due to their faded condition.

Four specimens, M. C. Z. 29549, 1 to if inches long from Chatham Island, 

 shore. 



The following color markings were noted. A specimen 25 mm. long had 

 side of head, body, and belly dark brown fading to pale dusky on dorsal surface 

 anterior to soft dorsal, becoming darker again on top of snout; posterior part 

 of caudal peduncle lighter; a line of pearly spots from tip of snout backward 

 across upper surface of eye to nape, other small pearly spots in front of and below 

 orbit and on opercle; base of spinous dorsal very pale, spines pale, membrane 

 dusky, a large black ocellus on last two dorsal spines and first two rays and 

 extending on body nearly to lateral line, rest of soft dorsal, caudal, and pectoral 

 slightly dusky; anal and ventral color of body, traces of lighter spots on posterior 

 base of soft dorsal and anal; outer ray of ventrals with an interrupted pearly 

 line; trace of a light spot near tip of pectoral. 



A specimen 46 mm. long similar to preceding, dorsal surface much darker 

 with traces of grayish, tips of membranes of spinous dorsal black, ocellus con- 

 fined to soft dorsal and body; pearly line from tip of snout to eye distinct, the 

 remainder of fine and other pearly spots not so marked; spot near tip of pectoral 

 more distinct than in smaller specimens.

Two specimens 31 and Sjs inches long, from Manga Reva. 



In the larger specimen the black saddle on caudal peduncle is very indis- 

 tinct, and the dorsal, caudal, and anal have very dusky edges, differing in this 

 respect from the smaller one and the young.
