64 MEMOIRS OF THE CARNEGIE MUSEUM. 



Morita and published by Jordan and Evermann under the name of Holacanthus 

 bispinosus. But the description 'pubhshed by Jordan and Evermann (" Fishes of 

 Hawaii," p. 378) was not taken from this species, but through some error, for which 

 I cannot at present account, from two Samoan examples of Centropyge diacantha 

 (Bloch). 



It is not clear that Giinther's description (" Fische der Slidsee") belongs to the 

 fish figured by him. 



Centropyge tutuihe is, tlu>refore, until now kno\«i only from two colored plates, 

 the first that of Gi'mther, indifferent in cjuality, the other that of Morita, which 

 is excellent. 



In Samoa this species is known as Tuu'ii pnlepule lauinu = broad fish, red- 

 striped. 



XiPHYPOPs'" gen. nov. Jordan. 



Type: Hokicnvthus fisheri Snyder. Distinguished by the presence of two 

 strong spines besides smaller serrse on the suborbital bone. The preopercle is also 

 strongly armed. Scales large, those above the lateral line scarcely reduced; caudal 

 rounded; profile convex; fourteen dorsal spines. 



372. Xiphypops fisheri (Snyder). (J. & E., p. 379.) 



A handsome fish, taken a few times in rather deep water. 



Family XC. ZANCLID.E (Moorish Idols). 

 Zanclus Cuvier and Valenciennes. 



373. Zanclus cornutus (Linnaeus). Kihikihi. (J. & E., p. 382.) 



Very common about the reefs. Zanclus canescens Linnaeus is thought by 

 Bleeker to be a distinct species, having a spine on the preorbital and no black 

 markings before the eye. It may be, as the writer has supposed, the young of the 

 common Zanclus cunmtus. The name canescens has one page priority over cornvtas. 



374. Zanclus ruthise Bryan. 



(Bryan, Report Bernice Pauahi Bishop Museum, II, 190'), p. 22, fig. 2 (1906).) 

 A single young speeinuni taken at Honolulu, two and three-ciuarters of an 

 inch long, remarkable for the great height of the first dorsal rays. The color is 

 quite unlike that of Z. cornutus, young or old, there being only a faint dark bar 

 across the interorbital and a broad obscure dark shade across body from dorsal to 

 anal, and another on caudal ]:)eduncle. Caudal mostly black, as are the long rays 

 of dorsal and the front of the anal and ventrals; lips black; tip of caudal ]mle; 

 profile very steep; depth nearly ecjual to length. D. VII, 38; A. Ill, p. 33. 



'" ^t0os = sword; viro = bdow; iliil/ = eye.
