Distribution. — This species seems to be limited to the Indo-Pacific 

 region and is best developed in shallow water in the vicinity of coral 

 reefs. Brady records it from 40 fathoms on the coral reefs of Hono- 

 lulu, Hawaiian Islands, and Bagg records it from a single Albatross 

 station, H4567, in 1,307 fathoms off the same islands. This is prob- 

 ably a case similar to those already mentioned where currents have 

 carried the tests of shallow water forms into the deeper water outside 

 the reefs. I have noted the species at Nero station 2042 in 55 fathoms 

 and Albatross station H3007 in 323 fathoms, both near the Hawaiian 

 Islands, and Albatross station H4881 off Blake Reef, southern Japan,

in 310 fathoms. This last station is the one already noted at which 

 there is developed a decidedly southern coral reef fauna. 



Chapman has found specimens of this species in which the mega- 

 lospheric proloculum was followed by a short spiral, and refers the 

 species to the genus Spiroplecta.
