Reef, Tahiti, which apparently establish the second record of this 

 species from the Society Islands. A magnificent specimen of 

 Stichopus horrens Selenka, also from Venus Point Reef, Tahiti, 

 gives apparently the first record of this holothurian from the 

 Society Islands since Selenka's type was obtained there, about 

 1867. 



The Pentacvla stage of two Synapta species larvae, pelagic in 

 plankton, taken in a surface to 140 fathoms depth haul in Flores 

 Straits, present two seldom seen stages of the development of a 

 species of this rather primitive genus. 



The distribution of the Holothuroidea is as follows : 



Holothuria impatiens Forskal, Falcon Island, Queensland. 



Holothuria arenicola Semper, Apia, Samoa. 



Actinopyga mauritana (Quoy and Gaimard), Venus Point 

 Reef, Tahiti, Society Islands. 



Stichopus horrens Selenka, Venus Point Reef, Tahiti, Society 

 Islands. 



Pentacta arae Boone, mouth of Saigon River, Cochin China, 

 11 fathoms, and Pulo Condore Islands, South China Sea, 7 fathoms. 



Emipta godeffroyi (Semper), Kaneohe Bay, Hawaii, low tide, 

 1 fathom. 



Synapta species, larvae, Flores Straits, surface to 140 fathoms 

 depth.
