This handsome species is moderately common about the coral reefs of Samoa. We did not find 

 it at Hawaii, and it is possible that Garrett's sketch on which the Hawaiian record rests was made at 

 Tahiti. The coloration of this species is almost exactly that of the West Indian "lock beauty," 

 Holacanthus tricolor, but the form of the body and fins is different. 



Four specimens were taken at Apia, and 8 at Pago Pago. Life colors of one from Pago Pago, 

 anteriorly brilliant yellow, slightly brownish tinged above pectoral, bordered behind by clear yellow 

 which covers throat, breast, pectoral, and ventral; body posteriorly lustrous blue-black, the color 

 including anal and most of dorsal; caudal and end of caudal peduncle brilliant yellow; a broad, blue- 

 black bar connecting eyes above, this bar fading below; an orange spot above gill-opening; edge of 

 opercle orange; lower lip slightly bluish; four orange spots below it, the anterior largest; spine of 

 preopercle grayish blue.

Five specimens from Apia, 12 from Pago Pago. This beautiful species is rather common about the 

 coral reefs of Samoa. The first good account of it is that of Dr. Gunther, under the name of Holacan- 

 thus cyanolis. Holacanthus flavissimus is evidently the same, the blue markings on the head being 

 inconspicuous in faded specimens. 



Life colors of a specimen from Apia, clear deep yellow, citron-yellow below, fins all the same; 

 dorsal, anal, and caudal with very narrow bright blue edge; a deep blue ring around orange eye; a 

 deep violet- blue bar on opercle with an orange edge behind; preopercular spines and two bars across 

 chin slaty blue; two slaty spots on breast; upper lip slaty. Gill membranes scarcely joined to isthmus. 



1170. Holacanthus bispinosus Gunther. Tu'u'u pulepule mumu. Hawaii (Gunther); Samoa; 



Tahiti; New Hebrides; Amboina. 

 Holacanthus bispinosus Gunther, Fische der Siidsee, 51, pi. 56, fig. c, Tahiti, New Hebrides, Hawaii. Bleeker, 

 Atlas, Chaet., 60, tab. vi, fig. 1, Amboina. 



This very small and neatly colored species resembles a Pomacentrus. It is rare about the reefs at 

 Tutuila, but two specimens being taken at Pago Pago. It was not found by us at Hawaii. The plate 

 in the Fishes of Hawaii is taken from a specimen from Pago Pago. 



Life colors, deep orange- or copper-red, clearer below; the head, back, and vertical fins blue-black, 

 the dark color forming about 18 narrow dark cross streaks on side as wide as the ground color; breast 

 and belly orange; sides of head dull orange, thq lips and spines violet; lower lip very bright blue; anal 

 and dorsal edged with blue; caudal with a broader blue stripe inside the margin; pectoral yellow, 

 dusky at base; ventral orange, edged with blackish. 



1171. Holacanthus navarchus Cuvier & Valenciennes. New Guinea (Macleay); East Indies.
