THE FISHES OF SAMOA. 363 



This handsome species is generally common at Honolulu and Samoa, thence throughout the 

 South Seas and East Indies. 



1252. Balistapus rectang-ulus (Bloch & Schneider). Sumu pulepule. Hawaii; Guam; Marcus I.; 



Samoa; New Guinea; Fate and Nukuhiva (Seale). 

 This pretty species is rather common about Hawaii, thence through the South Seas and East 

 Indies. We have a few specimens from Samoa. 



1253. Balistapus undulatus (Bloch & Schneider). Sumuuli. Samoa; New Britain; New Guinea; 



New Hanover; Guam; Tahiti; Shortland I., Fate and Raiatea (Seale); East Indies. 



Of this common East Indian species we have about a hundred specimens from the reefs of Samoa, 

 where it is very abundant. It was not seen at Honolulu. 



Life, colors of a specimen from Apia called sumu uli, deep livid olive green, shaded on back and 

 head; stripes anteriorly, scarlet on chin, yellow on lower lip; body covered by oblique stripes running 

 forward and backward; brassy orange on head; violet streaks on snout and side of head; golden brown 

 stripes on side; first dorsal golden, with blue spots; second dorsal golden, orange at base, violet blue 

 lower, the membranes bluish; caudal centrally yellow-orange, with violet stripes on margin; anal like 

 dorsal; a black patch on caudal peduncle; pectoral scarlet, black at base, pale at tip. 



1254. Balistapus oire (Bennett). Raiatea; Tahiti. 



Batistes oire Bennett, Whaling Voyage, n, 262, 1840, Raiatea, Tahiti. 



1255. Balistapus papuensis (Macleay). New Guinea. 

 Batistes papuensis Macleay, Proc. Linn. Soc. N. S. \V. 1884, 279. 



1256. Balistapus verrucosus (Linnreus). New Ireland; New Guinea; Shortland I. (Seale); East 



Indies. 



CANTHIDEEMIS Swainson. 



1257. Canthidermis rotundatus (Proc£). South Seas?; Philippines; East Indies. 



1258. Canthidermis angulosus (Quoy&Gaimard). Hawaii (Quoy&Gaimard) ; Laysan; Galapagos 



Is. (Snodgrass & Heller); East Indies. 



Batistes angulosus Quoy & Gaimard, Voy. Uranie. Zool.210, 1821, Maui. (Dorsal 23, anal 20. Color black, fins high.) 

 Batistes aureolas. Richardson, Voy. Sulphur, Fishes, 120, pi. 59, fig. 1, 2, East Indies. Gunther, Cat., VIII, 215, 1870, 

 young, East Indies. Steindachner, Sitz. Ak. Wiss. Wien 1900,517, Laysan. 



Of this species we know the published descriptions only, and these do not distinguish it from 

 Canthidermis rotundatus. Batistes aureolus, from the East Indies, based on young examples, is said to 

 differ from Canthidermis rotundatus in the larger scales. Balistes willughbei Bennett from Mazatlan 

 and Balistes adspersus Tchudi from Peru belong in this neighborhood. 



In all our explorations we have taken no species of Canthidermis in the Pacific. 



XANTHICHTHYS Richardson. 



1259. Xanthichthys lineopunctatus (Hollard). Hawaii; Revillagigedo Is. ; Bourbon I. 

 (Xanthichthys mento Jordan & Gilbert.) 



This species, not rare in rather deep water about volcanic rocks in the neighborhood of Hawaii, 

 was not seen in Samoa. It occurs among the Revillagigedo Islands off the coast of Mexico, and at 

 Laysan. The West Indian species, Xanthichthys rincjens, is probably different, but the species called 

 Balistes lineopunctatus by Hollard, based on an example from Bourbon Island, is apparently the 

 Hawaii-Mexican species. 



1260. Xanthichthys rivulatus (Ruppell). Fate, New Hebrides (Seale); Red Sea. 



MELICHTHYS Swainson. 



1261. Melichthys radula Richardson. Hawaii; Marcus I.; Johnston I.; Laysan; offshore islands 



of Mexico. 

 (Melichthys bispinosus Gilbert.)
