Test subglobular to pyriform, broadest toward the base, apertural 

 end tapering to a short slender neck ; wall ornamented with a few high 

 platelike costae, occasionally twisted, coalescing at the upper end and 

 forming a collar made up of a reticulate network below the neck. 



This species has a wide distribution both in the Atlantic and Pacific, 

 and it has been recorded in the Tertiary of Europe and the Pliocene 

 of California. The only specimen in our collections is the figured one 

 from Albatross Station H3965, Apaiang Atoll, in line with north point 

 of Tarawa, 2 miles N., in 170 fathoms.
