THE FISHES OF SAMOA. 341 



shoulders, with the broad white postocular band, are characteristic in the adult. The changes in the 

 young are well figured by Dr. Gunther. 



We have 15 specimens from Apia and Pago Pago. One was colored in life as follows: Deep golden, 

 a little olive-tinged and more dusky on back; chin gray; patch behind ocular stripe clear gray; oblique 

 black band bordered before and behind by clear golden brown, a blackish blotch at first dorsal spine 

 with golden brown behind it; spot on caudal peduncle and stripe on dorsal golden; a brown shade 

 across dorsal and anal besides black tips and dark brown bands; ventral golden with some dusky; 

 pectoral and edge of caudal colorless.

Of this rare species, hitherto known only from the scanty original description and from the 

 excellent figure given by Dr. Gunther, we have four specimens from Apia and Pago Pago. This 

 species is known by the presence of four distinct angular cross-bands, with some fainter ones. Behind 

 these is a broad yellow cross-band involving most of the dorsal and anal. 



The species (Chxtodon xanlhurus) called Telragonoptrus mertensi by Bleeker is distinct from this 

 species. 



Colors of a specimen from Pago Pago, bluish gray; rich orange-yellow behind last dorsal spine, on 

 body and dorsal and anal fins, including all of soft dorsal and most of anal; forehead and a scapular 

 bar dark brown; ocular stripe broader above, where it is white-edged, the two not meeting below; 

 five V-shaped blackish cross-bars on body behind shoulder, the angle toward the head; 4 rows of 

 spots in concavity of last bar, between it and the immaculate golden area; first dorsal light yellow; 

 second with edge of black and light yellow; anal dusky gray in front, edged with orange, posteriorly 

 like dorsal; caudal light yellowish gray at base, then deep orange-yellow, edged with a fine line of 

 black, then yellow; ventral soiled gray; pectorals plain.

This species is rather rare about Samoa, only seven specimens being taken at Apia and Pago Pago. 

 The diffuse black spot at the base of the anal and the black spot at the throat are characteristic traits. 

 Day has given a fair figure of the species. 



Life colors of a specimen from Apia, gray, the contour all bright yellow; a broad, blackish patch 

 occupying the whole back, this edged below by dull whitish; a large whitish blotch in the middle of 

 the back; scales with dusky rows of diffuse blackish spots running upward and backward, these more 

 streak-like above, the spots separate below, most distinct at base of anal, where they are gathered into 

 an oblique jet-black spot of irregular outline; a black streak along lateral line posteriorly, widened into a 

 jet-black blotch below last soft dorsal rays; a smaller black blotch above last ana' ray on edge of caudal 

 peduncle; ocular band narrow, edged on both sides with bright yellow; region before it brownish 

 yellow, clear yellow at throat, a dusky spot on breast; spinous dorsal deep brownish yellow; soft dorsal 

 dusky, then yellow, then a broad blackish band with a black line above, then clear yellow, with a 

 dusky edge; anal broadly clear yellow, with a brownish shade across it, then dusky, then a black line, 

 then clear yellow; caudal bright yellow, with a narrow, dusky shade, then a blackish cross line, the 

 posterior half translucent; pectoral colorless, light yellow at base; ventral golden yellow. 



Another specimen from Apia had the lower half of side light bluish gray, above blackish with 

 a pale area; margin all around yellow, golden below, orange above, with black markings, pectoral
