The height of the body is one-fifth of the total length (without caudal), the length of the head two-ninths. Head small, broader than high, its greatest width being four-fifths of its length ; snout of moderate length, rounded, its extent being three-fifths of the width of the interorbital space.

. Catalogue of the fishes in the British Museum. British Museum (Natural History); Fishes. 59. ARITTS. 157 y. Pacific species. 33. Arius dasycephalus. D. 1/7. A. 23. P. 1/11. The height of the body is one-fifth of the total length (without caudal), the length of the head two-ninths. Head small, broader than high, its greatest width being four-fifths of its length ; snout of moderate length, rounded, its extent being three-fifths of the width of the interorbital space. The eye is situated much nearer to the end of the snout than to that of the operculum ; its diameter is one-sixth of the length of the head, and one-third of the width of the inter- orbital space. Cleft of the mouth narrow. The teeth on the palate are villiform, and form a pair of separate, transverse, quadrangular patches, each of which is broader than long, and again composed of two portions. ^" The maxillary barbels extend to the middle, the outer of the man- dible to the root of the pectoral fin. The crown of the head is coarsely granulated, the gra- nules forming two bands di- verging in front and extend- ing to the snout. There is a pair of prominent, parallel, granulated ridges along the middle of the forehead, reaching to between the nos- trils. Occipital process tri- angular, as broad at the base as long, elevated into a ridge along its middle; basal bone of the dorsal spine small, crescent - shaped. Dorsal spine of moderate strength, three-fourths of the length of the head, slightly serrated in front and behind; the first soft ray is much longer than the spine and higher than the body. Adipose fin as long as dorsal. Caudal deeply forked, with the upper lobe longest, one-fifth of the total length. Pectoral spine rather stronger, but scarcely longer, than that of the dorsal fin, serrated along both edges. Ventral rather shorter than pectoral. Fins blackish. Sandwich Islands. a. Eleven inches long. Oahu. From the Haslar Collection.— This specimen is a pregnant female; on opening the left
