Family: PRAYIDAE 

 Subfamily: Amphicaryoninae 



Genus: AMPHICARYON Chun 

 Amphicaryon acaule Chun 



Type : Dr. Chun's type material was taken in the vicinity of 

 the Canary Islands. 



Distribution : This species has been recorded twice from the 

 Atlantic Ocean, namely, in the vicinity of the Canary Islands and 

 possibly also Bermuda (Chun) ; while Dr. Bigelow reported it 

 from the West Indies and from the tropical eastern Pacific seven 

 specimens were taken at seven "Albatross" stations in depths 

 ranging from 300 fathoms to surface. 



Material examined : One young colony, taken in 150 fathoms, 

 north of Nuka Hiva, Marquesas Islands, August 11, 1931, by the 

 "Alva." 



Remarks : This young colony, the only one taken in a large 

 haul of plankton, is like the specimen from the tropical eastern 

 Pacific shown in Dr. Bigelow's plate 4, figures 1 to 8. The present 

 specimen is quite young but shows clearly the short corm with its 

 appendages and the canal system of the two nectosarcs is trace- 

 able. This colony has a long diameter of 3.5 millimeters and shows 

 the older nectosarc but little larger than the younger.
