last dorsal spine and first 2 or 3 soft rays. The Atlantic form, Abudefduf marginatw, is distinguished 
by the shorter, more orbicular body and the absence of black blotches on soft dorsal and anal. 
We have examined 55 specimens of this species, all from Honolulu except 1 from Hilo and 4 from 
Kailua. They range in length from 3.4 to 9 inches. Specimens were also found by the Albatron* at 
numerous places among the Hawaiian Islands.
