THE FISHES OF SAMOA. 339 



characters separates the species from the closely related Chseiodon auriga of the southern coasts of 

 Asia. The lines at right angles on the body are also characteristic. The name tifilifi is given to all 

 cheetodonts in Samoa, though primarily applied to Zanclus canescens. Tiji means angle; tifilifi the 

 horns of the moon. The word corresponds to kihikihi of the Hawaiians. 



Life colors of a Samoan specimen, anteriorly gray, posteriorly deep lemon-yellow, with opposing 

 stripes of violet-gray; forehead gray, with deep orange-yellow cross streaks; ocular band broad, 

 meeting its fellow below; soft dorsal edged with black, with a large black spot; a yellow streak on 

 soft dorsal within the blackish edge; filament black before, yellow behind; caudal lemon-yellow; band 

 light bright yellow, bordered before and behind with brown; tip of caudal translucent; anal gray at 

 base, orange behind and outside, edged with a black line and yellow; pectoral and ventral clear gray.

 This species of the Indian region is not certainly known from the islands of the Pacific.

 Teiragonoptrus vagabundus, Bleeker, Atlas, Chset., 48, tab. xvi, Sumatra, Java, Celebes, and all other islands of the 



East Indies. 



This fish, abundant throughout Polynesia, is by far the most abundant species of the group at 

 Samoa. Seventy specimens were taken at Apia and Pago Pago. The species is not one of the 

 brightest in color. In the presence of narrow streaks meeting at right angles it resembles Chxtodon 

 setifer, but it has neither dorsal filament nor ocellus. 



Life colors of one specimen, gray, olivaceous above, becoming golden behind; oblique streaks of 

 purplish gray meeting at angles; ocular band broad, not pale-edged except below in front; forehead 

 gray, with six orange cross-shades; first dorsal black, with a median yellow streak which widens to 

 cover most of soft dorsal; a broad black margin to soft dorsal; a black bar at its base, edged before and 

 behind with yellow, which crosses caudal peduncle, ending below on center of anal; anal otherwise 

 dark yellow, grayish at base, with black and light yellow edge; spines very pale yellow; caudal 

 golden yellow with a black crescent, a black crossbar behind it, and a colorless tip; ventral and 

 pectoral pale. 



This species seems obviously near Chseiodon setifer, and lends some support to Bleeker' s group 

 Linophora.

 Chseiodon princeps Cuvier & Valenciennes, Hist. Nat. Poiss., vu, 33, 1831, New Ireland. 



This pretty species is rare about Samoa, nine specimens in all being taken at Apia and Pago Pago. 

 Giinther's figure is fairly good, but the color is too pale, the fish being more olive in shade. The 

 checker-like orange markings on the edges of the scales give a characteristic mosaic appearance. 



Colors in life, deep yellow, greenish-tinged on body, very bright on fins; the body checkered with 

 two sets of pinkish brown cross-streaks on edges of scales, these colors purplish on small scales at base 

 of fin; snout brown; forehead gray; chin bright yellow; ocular band broad,, whitish-edged only below 

 in front; soft dorsal greenish on scales, then clear brown, then clear yellow, black and yellow; spines 

 brownish, with greenish membranes; anal yellowish-green and purple-dotted on scales, then clear 

 brown with two yellow bars on last rays and a yellow edge, with a black and white bounding line: 

 caudal clear yellow with a black band, broadest in the middle, clear yellow behind, the edge clear 

 gray; pectoral gray; ventral bright golden.
