Color in alcohol, deep brown, dorsal and anal fins blackish; caudal dusky along middle of margin; 
side without blue or pale lines; margin of gill-opening dusky; pectoral dark brownish, margin broadly 
pale yellowish-white; ventrals blackish on outer portion, brownish on basal portions of rays, the mem¬ 
branes whitish; lips brown. 
Described from an example (No. 05662) taken at Honolulu. This species has been recorded from 
Oualan, Isle of France, and the Hawaiian Islands. It does not appear to be common, as only 1 small 
specimen was secured by Jenkins and 3 by us, all from Honolulu. Our examples are 6 to 14.5 inches 
long.
