 Cliiduitvn Jranblii. Cuvier & Valenciennes, Hist. Nat. Poiss., vii, 24, 1831; after Bennett. 

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

 the Hawaiian Islands, where it is rather rare. 



MICR0CANTHU8 Swaineon. 



Microcanthus Swain.son, Class. Anim., ii, 1839, 215 {strigatus). 

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

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

 species being dorsal xi,17; anal iii,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 Hemiiaurichthyg (type polylepis), which is apparently a valid genus, with no close relation to 

 MicTocanthus sirigatus. 



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. 



HENIOCHUS Cnvier & Valenciennes.

 Taurichthys Cuvier & Valenciennes, Hist. Nat. Poiss., vii, 146, 1831 (varius). 

 Diphreules Cantor, Malayan Fishes, 159, 1850 (macrolepidolm); substitute for Heniochns, on 

 account of Henioche, a prior genus of Lepidoptera. 

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

 The species are all marked by dark cross-bands. 



1162. Heniochus acuminatus (Linnwus). Lanlaufdu. Hawaii; Samoa; Fiji; New Britain; New 



Hanover; New Guinea; East Indies. 

 Cliselodon acuminatus lAnn^ns, Syst. Nat., ed. x, 272, 1758, Indies; after Chxtodon fascius S-fusca.

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

 Taurichthys macrolepidotus. Sleeker, Atlas, Chset., 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, agray 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 acuminatus 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., vir, 99, 1.S31, no locality.

Heniochus drepanoidesThioUi^re, 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-
