Both microspheric and megalospheric specimens were found at 

 numerous stations. This seems to be a species which is pecuHar to 

 coral-reef regions as has been noted in its occurrence elsewhere. 



In the remainder of the North Pacific it is known as far north as 

 southern Japan and as far east as the Hawaiian Islands. South- 

 ward the records include the Admiralty and Friendly Islands, but it 

 is not recorded from the Australian region except as a fossil, nor did 

 I find it in the material I have had from Murray Island on the Great 

 Barrier Reef of Australia. Chapman records it from Funafuti. 

 Brady gives a record from the Gulf of Suez, but Heron-Allen and 

 Earland do not record it from the Kerimba Archipelago off south- 

 eastern Africa. Its distribution, therefore, while wide, is evidently 

 restricted witliin this range.
