Ulea; Paumotu Is.; Rarotonga and Baiatea (Seale). 

 Chxtodon reticulatus Cuvier & Valenciennes, Hist. Nat. Poiss., VII, 32, Tahiti, Ulea. 

 Chxtodon coUaris Gunther, Fische der Siidsee 40, Paumotu; not of Bloch nor of Bleeker. 



? Chxtodon bellicosus Quoy & Gaimard, Voy. Astrolabe, 1835; a handsome brown-colored species seen at Guam 

 but not secured; " bit at the finger when approached." 



This splendid species is rather rare about Samoa, only 12 specimens being taken at Apia and 

 Pago Pago. It is quite different from Chsetodon collaris of the East Indies, with which it has been 

 confounded by Gunther, who gives a good figure, but the colors of the fish are brighter than his plate 

 would indicate. The scarlet patch on the anal is especially characteristic. 



Life colors of a specimen from Apia, black, dove-gray above and behind ocular band; spots on 

 scales bright yellow below, gray above; edge of ocular stripe golden; forehead and snout drab; lips 

 golden; dorsal drab, edged with golden, with a dark and white streak; caudal black, then drab, black, 

 yellow, black, then a drab edge; anal black, being scarlet behind, with 2 black stripes, a dull yellow 

 one, the edge white; ventral and breast black, continuous with ocular band; pectoral colorless. 



1145. Chaetodon unimaculatus Bloch. Tifitifi pulepule; Tifitifi samasama. Hawaii; Samoa; Tahiti; 



New Guinea (Macleay); Bonham I.; Fat6 (Seale) ; East Indies.

 Ceram, Banda. 



This handsome species is widely diffused throughout the South Seas and to the East Indies and 

 Hawaii. We have 20 examples from Samoa. The single black spot on the side well characterizes the 

 species. 



Life colors of a specimen from Apia, clear bright light yellow, becoming bluish gray below; ocular 

 band broad, meeting below; faintly edged with gray; snout gray; golden edges to scales making faint 

 oblique yellow streaks on shoulder; black lateral spot, broadly surrounded by gray, with a wedge- 

 shaped downward extension of dusky gray; dorsal light bright yellow, a black bar across its posterior 

 part and across caudal peduncle and anal fin, where it is narrower, the band bordered before and 

 behind by gray, the posterior edge very narrow; caudal colorless; anal deep golden yellow, darker 

 than dorsal; ventral deep golden yellow; pectoral colorless. 



Another specimen was in life light golden above; gray beneath shoulders and front of sides, with 

 V-shaped vertical bars of deep yellow, the angle directed toward the tail; ocular band very broad 

 from front of dorsal, meeting across breast; snout and forehead gray; a large round black spot on 

 middle of side of back, surrounded by gray; dorsal and anal clear yellow; a dark bar posteriorly on 

 both, extending across caudal, edged on both sides with gray; posteriorly this is the margin of the 

 dorsal and anal fins, both with whitish edge; caudal grayish white at base behind bar; rest of fin like 

 pectoral, translucent with black dots; ventral golden yellow. 



Compared with Hawaiian specimens there is a tendency in these to form a larger spot, more 

 extensively produced into wedge-shaped process below. There is no other difference. 



Chivtodon unimaculatus differs strikingly from Chxtodon eplrippium and ulietensis in the teeth, which 

 are stronger, not flexible, not more than two series functional, those of the two halves of each jaw 

 converging toward median line. The horizontal series of enlarged scales on anterior part of sides are 

 less marked than the oblique series, but are distinguishable and usually continuous with the horizontal 

 series of smaller scales behind. The larger scales have margin unequally curved {Lepidochxtodon) , 

 but this character seems to have little value. 



1146. Chaetodon trichrous Gunther. Tahiti. 



Chxtodon trichrous Gunther, Fische der Sttdsee, 40, pi. 3G, Tahiti; on a drawing. Jordan & Snyder, Proc. D. S. 

 Nat. Mus., xxix, 1905, 355, fig. 2, Tahiti. 



This species is known from an incorrect drawing made by Andrew Garrett, and published by 

 Dr. Gunther, and from a specimen, also from Tahiti, taken by Mr. Henry P. Bowie. 



1147. Chsetodon kleini Bloch. Yap; New Britain; East Indies. 



Chxtodon kleini Bloch, Ichth., iv, 7, taf. 218, fig. 2, after Klein. Gunther, Cat., II, 22, Amboina, Mauritius. Peters, 

 Berl. Mon. 1876, 832, New Britain.
