1.7 in head; other dorsal spines smoother and more slender, the fifth 2 in head; soft dorsal not high, 
the rays of about uniform length, the longest about 2.5 in head; anal spines rather short and slender, 
the second equal to diameter of orbit; soft anal similar to dorsal, equally high; caudal deeply 
emarginate, the free edge of the 2 lobes forming a broad angle; upper lobe of caudal somewhat the 
longer, its length nearly equaling head; ventral spines moderate, reaching base of first anal spine,

Only 2 examples of this species were obtained. Type, No. 50707, U. S. N. M. (field No. 382), a 
| specimen 8.25 inches in length, obtained by me in Honolulu in 1889; cotype, No. 7726, L. S. Jr. Univ. 
Mus. (field No. 12048), 11 inches long, obtained by the Albatross in 1896, at Honolulu. 
191. Acanthurus brevirostris (Cuvier & Valenciennes) . 
Color in life (field No. 244, 7.25 inches in length), head, body, dorsal and anal fins uniformly 
dark; outer margin of caudal yellow, central area light orange. 
Four specimens, 7.25, 7.75, 8.25, and 8.75 inches in length, were obtained. This is the first record
