1160. Chaetodon fremblii Bennett. Hawaii; Laysan. 



Chsetodon fremblii Bennett, Zool. Journ. iv, 42, 1829, Sandwich Is. Gunther, Fisehe der Stidsee, II, 39, taf. 29, fig. b, 



Sandwich Is. Steindachner, Sitz. Ak. Wiss. Wien 1900, 488, Laysan. 

 Chsetodon fremblii, Cuvier & Valenciennes, Hist. Nat. Poiss., vn, 24, 1831; after Bennett. 



This handsome species, well distinguished by its stripes of clear blue, has been found only about 

 the Hawaiian Islands, where it is rather rare. 



MICROCANTHUS Swainson. 



Microcanthus Swainson, Class. Anim., II, 1839, 215 (strigatus). 

 This genus differs from Chxtodon chiefly in the small scales, there being about 60 in the lateral 

 line. The soft dorsal and anal are shorter than is usual in Chxtodon, the fin formula of the typical 

 species being dorsal xi,17; anal ui,14. It is in fact doubtful whether the genus contains another 

 species, as the other species with small scales have the soft fins many-rayed and constitute Bleeker's 

 genus Hemiiaurichthys (type polylepis), which is apparently a valid genus, with no close relation to 

 Microcanthus strigatus. 



1161. Microcanthus strigatus (Cuvier & Valenciennes). Hawaii; East Indies. 



This species', common in southern Japan and the East Indies, is occasionally taken about Hawaii. 

 It was found there by Garrett, by Jenkins, and by Jordan & Evermann. 



HENIOCHT/S Cuvier & Valenciennes. 



Heniochm Cuvier & Valenciennes, Hist. Nat. Poiss., vn, 92, ]831 (macrolepidotus). 

 TauricMhys Cuvier & Valenciennes, Hist. Nat. Poiss., vn, 146, 1831 (varius). 

 Diphreules Cantor, Malayan Fishes, 159, 1850 (macrolepidotus); substitute for Heniochus, on 

 account of Henioche, a prior genus of Lepidoptera. 

 This genus is characterized by the deep body and by the prolongation of one of the dorsal spines. 

 The species are all marked by dark cross-bands. 



1162. Heniochus acurninatus (Liniueus). Laulaufau. Hawaii; Samoa; Fiji; New Britain; New 



Hanover; New Guinea; East Indies. 

 Chsetodon acurninatus Linnaeus, Syst. Nat., ed. x, 272, 1758, Indies; after Chxtodon fascius 3-fusca. 

 Chsetodon macrolepidotus Linnpeus, Syst. Nat., ed. x, 274, 175S, Indies; after Chsetodon Uriels utruique S-nigris, of 



Arttdi. 

 Heniochus macrolepidotus, Cuvier & Valenciennes, Hist. Nat. Poiss., VII, 93, 1831, Molucca, lie de France, Manila, 



New Guinea, Trincomalee. Gunther, Fisehe der Siidsee, 48, taf. 37, Polynesia. 

 TauricMhys macrolepidotus, Bleeker, Atlas, Onset., 29, tab. v, fig. 1, Luzon, New Guinea, Singapore, Sumatra, and 



all East Indian islands. 



This widely distributed species is not common in the South Seas. We have specimens from 

 Hawaii and a single large specimen from Apia. 



The latter in life showed the following colors: Head gray; snout black above, a gray streak between 

 eyes; no ocular band; two black bands, the first including the short dorsal spines across to breast, 

 ventrals, and whole front of anal; second including last dorsal spines and most of soft anal; a short 

 white bar behind this; second dorsal and caudal bright golden; pectoral golden; lips pale; long spine 

 white. 



The name acurninatus has two pages priority over macrolepidotus. 



1163. Heniochus permutatus Bennett. Tahiti; Samoa; New Guinea; Woodlark I.; East Indies. 

 Heniochus permutatus Bennett in Cuvier & Valenciennes, Hist. Nat. Poiss., VII, 99, 1831, no locality. 



Heniochus chrysostomus Cuvier & Valenciennes, Hist. Nat. Poiss., VII, 99, 1831, T^iiti. Gunther, Fisehe der Siidsee, 



49, taf. 39, fig. A, Paumotu, Tahiti. 

 TauricMhys chrysostomus, Bleeker, Atlas, Chaet., 29, tab. iv, fig. 2, Flores, Ternate, Ceram, Amboira, Banda, Goram, 



New Guinea. 

 Heniochus melanistion Bleeker, Bydr. Ich. Banda. Banda 

 Heniochus drepanoides Tliiolliere, in Montrouzier, Fauna Woodlark Island, 166, Woodlark I. 



This species is rather rare about Samoa, where 7 specimens were taken, 5 from Pago Pago, and 2 

 from Apia. It is apparently identical with the species called Heniochus permutatus by Bennett, sue-
