Color greyish-silvery, and ornamented with five oblique blackish-brown bands which are disposed as follows: one extends from the snout to the preopercular margin, the second starts from the eye and terminates on the pectoral base, the third, which passes over the occipital region, extends below the pectoral axilla; the fourth, which is much broader, starts from the origin of the dorsal fin, curves downward and backward, becoming wider in its descent, and passes beneath the abdomen; the fifth one commences on the upper anterior half of the spiny dorsal, extending along the back to near the termination of that fin. Three irregular, pale spots may be observed in the dorsal band, and three large blackish-brown spots on the caudal trunk. The opercular flap and snout tinged with orange-red. The interorbital space is marked with two transverse brownish-red bands. Irides yellowish-silvery. That portion of the dorsal fin anterior to the fifth band is white, the remainder, together with the anal and caudal, light-yellowish, the latter tipped with blackish-brown. The pectorals are orange-red, and the ventrals are deep blackish-brown. Length, 7 inches. Habitat, Sandwich Islands. REMARKS.—An extremely rare fish, of which the solitary specimen now before me is the only example that has come to my notice. It is the more interesting in a geographical point of view, as being the only species—as near as I can ascertain—recorded from the Polynesian Seas. Sir John Richardson, in his interesting “Notices of Australian Fish,” published in the “Proceedings of the Zoological Society of London,” describes, and gives a list of thirteen species. Nine of those occur in the Australian Seas, one from China and Japan, two from the Cape of Good Hope, and one from Tristan d’Acunha. In the number and arrangement of the fasciae, our fish closely resembles the _C. gibbosus_, Sol., (_Chætodon_) from Van Diemen’s Land. The latter species is less gibbous, the eyes smaller, the soft portion of the dorsal fin shorter, and the caudal forks are more pointed than in the _C. vittatus_.
