FISHES OF HAWAIIAN ISLANDS. 
389 
with an intercalary band which in some examples makes 5 bands; anal with 4 similar ones; pectoral 
yellow; yellow area through eye; yellow line over snout. 
Color in alcohol, dark brown, vertical fins darker; side plain or uniform brown, without any 
lines; soft dorsal and anal grayish posteriorly; both dorsals and anal with 4 broad deep brown longi- 
tudinal bands; caudal deep brown, apparently without spots, base of fin pale; pectoral brown on 
basal portion, marginal portion broadly yellowish-white. 
Described from the type taken by Doctor Jenkins at Honolulu. 
This species is of rather wide distribution among the islands of the tropical Pacific, having been 
recorded by Gunther from the Caroline, Society, Navigator, Pelew, and Kingsinill islands, and iden- 
tified with Acanthurus blochi of Cuvier and Valenciennes. 
Twelve specimens were obtained at Honolulu by Doctor Jenkins and 2 by us. We also have 3 
examples from Hilo. Our specimen's are 1.5 to 8.6 inches long. Perhaps identical with H. vialoid.es.

Description from an example (No. 05354) 7.75 inches long, taken by us at Honolulu. The species 
is of wide distribution and has been recorded from Fiji Islands, China, Kotosho (Formosa), Mivoko 
Island, Biukiu, New Hebrides, Pelew and Tahiti islands, as well as from the Hawaiian Islands. It 
was obtained by Doctor Jenkins at Honolulu and by us at Honolulu and Hookena, Kona; also by the 
Albatross at Puako Bay, Hawaii, and at station 3834, on the southern coast of Molokai, in 8 fathoms. 
We have examined 28 specimens, which range in length from 4.4 to 8.4 inches.
