This species ranges widely through the East Indies. We have 50 specimens from Apia and 

 Pago Pago. The j'ellow form, called /accsfeH-s, we did not find in Samoa. The two forms, ftavesceng 

 and rhombeum, are without much doubt color variations of one dichromatic species. 



Life colors were noted in various specimens as follows: 



(1) Specimen from Apia, called (7m. Dark olive, somewhat clouded (a curved light blue streak 

 behind the eye, parallel with the golden iris, in young only) ; everywhere fine oblong light blue spots, 

 smaller and sharply defined on .side of head, not evident on snout nor along the back; larger below 

 and behind; fins all plain olive-black, the pectoral lighter olive; caudal spine bluish white; a short 

 oblique streak of light olive above pectoral. 



(2) An older example with light blue wavy streaks on body, not spots; streak above pectoral 

 light yellow and very conspicuous; no blue behind eye; pectoral scarcely olive. 



(3) From Apia. Dark brown, grayish behind, with about 20 fine bluish white cross-streaks; a 

 whitish lateral streak above pectoral; fins all dusky. Larger ones more sharply colored. 



(4) From Pago Pago. Po.sterior half of body fuliginous, darkest behind and merging anteriorly 

 into yellow-green with fine pale blue specks; olive-green above eyes; iris yellow. 



(5) From ."Ipia. Blackish; faint bluish horizontal lines over body as in Ili-pnlus Unmhilut:; a 

 yellowish white short band above pectoral; head unspotted; fins dark. 



(6) Specimen from Pago Pago, called iliu. Blackish brown; head, breast, and shoulders every- 

 where covered with fine bluish white dots; body with horizontal wavy stripes of the same color, on a 

 bronze-brown ground; fins dusky olive, unstriped; dorsal, anal, and caudal with a fine paler edgf ; 

 pectoral dark orange, dusky above and below; a long whitish stripe above pectoral. 



(7) One specimen was almost black, the spots very distinct, the stripes mostly obsolete; the 

 yellowish white line reduced to a round bright yellow spot near gill-opening, wanting on the other 



de; iris pink red, not gray as usual. 



210. Zebrasoma rostratum (Giinther). AIL Tahiti; Samoa. 

 Acanllmrus rostratus Giinther. Fische der Sudsee, 117, taf. 61, lig. E. Tahiti. 

 This species is close to Zebrasoma rhombeum, but the snout is longer, the fins rather higher, and 

 the color almost black. We havc^tw^ examples from Apia, a little smaller than Giinther's type, and 

 with the body deeper. ^<^ 



Life colors of a specimen called iliu, black, with brownish tinge; snout reticulate; a vertical bar 

 behind pectoral golden olive, with blue cross streaks; a similar bar from beginning of dorsal across 

 opercle and obliquely across breast; five blue stripes and four olive between; below pectoral obscurely 

 reticulate, with bluish around dull olive spots; fins uncolored; caudal with narrow pale edge; caudal 

 spine black, as are all fins. 

 1211. Zebrasoma veliferum (Bloch). Lupo. Hawaii; Samoa; Fiji; East Indies.

 This species is rather common about Samn.i, whence we secured four examples. It is even more 

 fre<iuent about Honolulu. Our largest exampl.-, alnim a foot long, corresponds very closely to Bloch's 

 figure of relifer. The caudal is dark, and the 1 .. i^ 1\ i^^ cri ■^>l■'l by many dark cross-streaks, which cross six 

 orseven obscure dark cross-shades, the most ili.stimt being the ocular and scapular bands. In younger 

 examples the cross-streaks are fainter, and in still younger they are wanting. The face is spotted with 

 pale and the six or seven dark cross-bands become more distinct. This form from 4 to 8 inches long 

 represents hypseloplerum. Still younger forms have the snout and caudal yellow. We have none 

 which correspond exactly either to desjardinii or to rnpjnUii. 



Life colors of a specimen from Pago Pago, violet-lilaek with four distinct yellowish cross-bands 



(grayish in formalin); these and rest of body cro.ssed by regular dark bronze streaks; broad black 



ocular band reaching base of ventrals; head before it with network of bluish white spots; another dark 



area from base of dorsal to fr^ntof anal; fins blackish; caudal with narrow pale edge; breast unspotted. 



\ specimen from .\pia, called hipo, had the snout and forehead dark yellow; ocular streak black
