Form oval. The head enters about four and a half times in the total length. The upper line of profile from the snout to the dorsal fin is nearly straight, rising at an angle of 60°. The snout is short. The eye is large, circular, its diameter one-third of the length of the head, and placed just midway between the opercular corner and the end of the snout. The preopercular margin exhibits a few small dentations. The scales are moderate size. The dorsal and anal fins are posteriorly rounded off. The hinder margin of the caudal is truncate. The anterior soft ray of the ventrals is slightly prolonged beyond the margin of the fin. Color creamy-yellow. The sides are marked with five vertical, yellowish-brown, diffuse stripes, the two anterior ones terminate on the side of the belly, and the others at the base of the anal fin. There is a slight indication of a sixth one along the basal half of the soft portion of the dorsal fin. Each scale is marked with a faint, yellowish-brown dot. A yellow line starts from a point above the base of the ventral, follows the line of the belly, and unites with a black one which traverses the anal fin. A blue black spot in front of the dorsal fin gradually passes into the ocular fascia, the latter being brown above and yellow beneath the eye. Irides chrome-yellow. Upper lip brown. A vertical black stripe, shaded off anteriorly with vermillion, marks the middle of the caudal trunk. The dorsal spines and filaments are orange-yellow, the inter-radial membrane is colorless. The soft portion of the dorsal and anal are ochre-yellow along their middle-third, the former with a broad yellow and the latter with a pale greenish margin. The two colors on either fin separated by a narrow black and white line. The caudal is colorless, with a basal vertical luniform bar, its convex margin anterior. The ventrals are whitish, and the pectorals colorless. Length, 3½ inches. Habitat, Sandwich Islands. REMARKS.—Two examples of this species were procured in Honolulu market. OPHISURUS Lac. _Ophisurus Californiensis_ Garrett. This _Ophisurus_ is more robust than usual in species of this genus. The head is large, swollen beneath, and comprises about one-twelfth of the entire length. The depth, taken at the origin of the anal fin, enters about twenty-eight times in the total length, or twice in the length of the head. The pectorals are large, elliptical in shape, their tips reaching posteriorly nearly as far as the origin of the dorsal fin. The dorsal and anal fins are well developed, the latter passing over a base considerably more than half the length of the fish.
