 ited in the Berlin Zoological Museum, where it is recorded from 

 an unknown locality. 



Distribution : It has since been recorded from the Seychelles 

 Islands, Fernando Velosa, New Ireland, Little Santa Cruz Island, 

 Zamboanga, Philippines, Batavia, Sharks Bay, southwest Aus- 

 tralia, Samoa and the Fiji Islands (Koehler) . The present "Ara" 

 record appears to be the first of this species from the Hawaiian 

 Islands. It is restricted to the littoral zone.

 specimen taken at low tide, depth one fathom, Kaneohe Bay, Oahu, 

 Hawaiian Islands, December 15, 1928.
