pupil over top of head and dorsal portion of body; 4 transverse bands of golden on caudal tin; pectoral 
covered with dusky golden spots smaller than pupil anteriorly, larger and less distinct posteriorly; a 
bright bracket-shaped yellow band on upper side of dorsal about one-third distance from base to top, 
concave side toward base; spinous dorsal membrane olivaceous with dusky golden spots; soft dorsal 
membranes transparent, rays with alternating white and olive areas; ventrals golden; anal transparent, 
with golden color on rays. 
Color in alcohol, dull purplish brown, with rather large dark round spots on the back, lower

We have examined 6 examples from Hilo, 3 from Honolulu, and 1 from Molokai, ranging in 
length from 6.5 to 14 inches. 
One specimen was obtained by Doctor Jenkins at Honolulu in 1889, and the Albatross collected 
specimens at Honolulu; Puako, Molokai; Hanalei Bay, Kauai; and Lahaina, Maui.
