smaller than pupil of eye and with many smaller spots of more or less equal size distributed in oblique 
rows above, becoming straight on side below; fins all pale. 
Described chiefly from example No. 04556, from Honolulu. 
Our collection contains 37 excellent specimens from Honolulu, where it is common about the 
coral reefs, and 4 from Hilo, ranging in length from 1.5 to 6.25 inches. Of those from Honolulu 1 was 
collected by Jordan and Snyder in 1900 and 8 by Doctor Jenkins.
