CHORISTISTIUM Poey. 



This genus has been hitherto known from a single species taken by Poey in Cuba, and named 

 Chorististium rubrum. The discovery of a second species is most interesting. 



535. Chorististium. susumi Jordan & Seale, new species. Susu umi. Samoa. 



Head 2.55 in length; depth 3.40; eye 4.50 in head; dorsal vi-r, 10; anal in, 8; scales 3-49-11; inter- 

 orbital equal to eye. 



Body elongate, compressed; scales of moderate size, striated and ciliated, entirely covering head 

 and body; lateral line strongly curved, the straight portion 2 in curved; snout rather wide but acute; 

 the lower jaw slightly the longer; maxillary 2.40 in head, extending to posterior third of eye; a distinct 

 supplemental bone; mouth large, with broad bands of villiform teeth in jaws, vomer and palatines, the 

 inner row in jaws slightly longer and depressible; no teeth on tongue; gillrakers equal to one-half eye, 

 13 on lower limb; longest spine of dorsal 2.75 in head; distance between last dorsal spine and origin 

 of soft dorsal 4.50 in head; base of soft dorsal equal to depth of caudal peduncle, its margin somewhat 

 rounded, its longest ray 2 in head; caudal bilobed, its longest ray 2 in head; base of anal equal to 





'..'/K 



Fig. 48. — Chorististium susumi Jordan & Seale, new species. Type. 



longest (2nd) anal spine; its longest ray 2.10 in head, pectoral equal to distance from middle of eye to 

 posterior margin of opercle; ventrals inserted directly below the base of pectorals, their length 1.55 

 in head; opercle armed with three flat spines, the two lower ones closest together; preopercle slightly 

 serrate. 



Color in spirits, light brown, with seven longitudinal lines of deeper brown on sides; four of these 

 lines arise from posterior margin of orbit and extend to or near base of caudal; the remaining three 

 seem to arise at margin of opercles and extend about to a line with axis of soft dorsal; fins all uniform 

 yellowish white. 



Life colors of one specimen ironi Apia, dark brown suffused with red, redder below and behind; 

 about seven olive-red stripes, very dark on body, these not extending much on head; fins all plain 

 bright cherry red. 



Two specimens from the reef at Apia. The type is no. 51738, U. S. National Museum, 3.10 inches 



long. 



CENTROGENYS Richardson. 



536. Centrog-enys waigiensis (Quoy & Gaimard). New Guinea; Australia; East Indies. 



PARACANTHISTIUS Bleeker. 

 (Pltclropoma Boulenger, not les Plectropomes of Cuvier= Plectropomus Oken. ) 



537. Paracanthistius maculatus (Bloch). Samoa, Louisiades; Fiji; Palau Is.; New Guinea 



(Macleay); Fate (Seale). 

 One large example taken at Apia. It belongs to the form called leopardus, the body covered with 

 round blue dark-edged spots, none of them elongate. This is apparently not specifically distinct from 

 the true maculatus, in which these spots are larger, some ol them oblong or elongate. 



538. Paracanthistius oligacanthus (Bleeker). Caroline Is. ; East Indies.
