Fig. 112. — Dascyllus albisella Gill; after Bleeker. 
Our collections contain 40 specimens ranging in length from less than half an inch to 4.75 inches, 
all from Honolulu except one, which was collected at Waikiki Beach. This pretty little fish is rather 
common in crevices of the coral reefs. Apparently the Hawaiian species, albisella, is different from the 
common trimaculatus of the South Seas.
