BULLETIN OF THE UNITED STATES FISH COMMISSION. 
The above description is based chiefly on the type (No. 2175 of O. P. Jenkins’s collection, 50692, 
U. S. N. M.), 2.6 inches long, from Honolulu, where Doctor Jenkins obtained 80 other examples from 
the coral rocks of the reef, ranging from 1.3 to 2.6 inches long. The species is known only from 
Honolulu and Waikiki.
