Test elongate, tapering, 2)2 to 3 times as long as broad, periphery- 

 rounded, initial end bluntly pointed, apertural end obliquely rounded; 

 chambers numerous, somewhat mflated; sutures very slightly de- 

 pressed, not very distinct; wall ornamented by a series of large 

 coarse punctae somewhat irregularly arranged, those of the last- 

 formed chambers finer and more numerous; aperture elongate, extend- 

 ing from the base of the inner margin of the last-formed chamber to 

 the highest point of the chamber. Length, up to 0.75 mm,; breadth, 

 0.25-0.30 mm.; thickness, 0.12-0.15 mm. 



This is a widely distributed species in the Pacific material and is a 

 striking one in its characters. The early portion of the test has a 

 pearly luster and is very distinctive, the ornamentation consisting of 

 coarse depressions with the portions of the wall between often raised 

 into low platelike areas. Most of the records are from the deeper 

 Albatross stations where it is often common, but it has also occurred 

 somewhat less abundantly at the following shallow-water stations: 

 Off Fiji, 40-50 fathoms; off Levuka, Fiji, 12 fathoms; off Nairai, Fiji, 

 12 and 24 fathoms; Viva Anchorage, 3 fathoms; and Mokaujar 

 Anchorage, Fiji. It was abundant off Niau, and less abundant from 

 Pinaki Atoll inside the lagoon. There are specimens also from 

 Rangiroa; Vavau Anchorage, Tonga Islands, 18 fathoms; Guam 

 Anchorage, Ladrone Islands, 21 fathoms; Rongelap Atoll, Marshall 

 Islands; and from Makemo Lagoon, Paumotu Islands.
