 Qennchxtus Gill, Proc. U. S. Nat. Mus., 1884, 277 (strigosus). 

 This genus contains species with slender movable teeth, each dilated at the apex.

 .Vneiteum, East Indies. Peters, 1. c. New Britain. New Ireland. 

 This species is generally common throughout Oceania. We found it abundant both at Hawaii 

 and Samoa. The faint spots about the head and the faint streaks along the sides disappear in spirite. 

 Life colors of a specimen from Apia, caWed palagi, blackish brown, unmarked; dorsal with very 

 faint horizontal strealis of bluish and bronze; anal very obscurely marl^ed in the same way; caudal 

 deeply forked; no stripes on body. 



Another specimen was exactly like Hepatus atramentntus, but the profile of the head was much 

 more convex: many wavy blue and bronze stripes on a blackish ground. 



COLOCOPUS Gill. 

 Colocopus Gill, Proc. U. S. Nat. Mus. 1884, 279 {lambdurus). 

 This genus differed from Bepatm in having but two or three soft rays in the ventral fins. 



1207. Colocopus lambdurus Gill. New Bri tarn; Kingsmill I. ; New Guinea (Macleay); Mauritius.

 Cvlorupus lambdurus Gill. Proc. U. S. Nat. Mus.. mS4, 279 (after Giinther), Kingsmill I., Mauritius. 



ZEBSASOUA Swainaon. 



Zehrasoma Swainson, Nat. Hist. Anim., ii, 2.56, 18.39 {velifer). 

 Scopas Kner, Novara Fische, 1865, 212 (scojms). 

 This genus differs from Hepatus in the short spinous dorsal of 4 or 5 graduated spines; soft dorsal 

 high: snout short, projecting at an angle. 



1208. Zebrasoma flavescens (Bennett). Samasama. Hawaii; Marcus I.; Guam: New (iuinea 



(Macl.-ayi.

 Acantliurus virgatus Vaillant & Sauvage, Ann. Sci. Nat., 1875, 283, Honolulu. 

 Acanthurus agana Seale, Bishop Museum, 1901, 110, Guam. 

 This species is rather common about the Haw-aiian Lslands, and is reported from (Suam under the 

 name of Zehrasoma agana. Zehrasoma virgafum must be the young of this species, with blue sjiots on 

 the head and brown blue streaks and pale cross-shades on the body. The description differs from 

 Zehrasoma jhu-escens as the young of Zehrasoma rhomheum differs from the adult. 



This species apparently agrees with Zehrasoma rhomheum in all respects except color. Were it not 

 for its geographical separation we should follow Gunther in uniting rhomheum with Jhire.'ieens. The 

 two are in fact probably the same species, the na.me flavescens being the older.
