Test fairly large for the genus, slightly curved, initial end with a 

 single, stout spine, later part of test slightly lobulate; chambers distinct, 

 inflated only in the later portion, increasing rather gradually and evenly 

 in size as added ; sutures distinct, only the later ones depressed ; w^all of 

 the earlier portion with distinct longitudinal costae extending across the 

 sutures, later portion smooth ; aperture radiate, terminal, slightly project- 

 ing. Length up to 5 or 6 mm. ; diameter up to 0.65 mm. 



This somewhat variable form has been recorded from the Pleistocene 

 of California and it is not surprising to find it living off the coast.

Distribution. — Stations 1007 through 1246 are off the Channel Is- 

 lands and show a range in depth from 16 to 267 fms., the average being 

 60 fms. Stations 207 to 2168 give a range 23 to 95 fms. with 55 fms. being 

 the average. The Galapagos Stations 412 to 475 show 45 to 195 fms., the 

 average being 109 fms. Some of the best specimens were from San Miguel 

 and Tower Islands.

Test elongate, slender, of nearly uniform diameter throughout, initial 

 end terminating in a short spine; chambers few, of rather uniform size 

 and shape, the proloculum longer than any of the succeeding chambers ; 

 sutures slightly depressed, strongly oblique ; wall smooth ; aperture termi- 

 nal, radiate. Length 0.85-1.15 mm.; diameter 0.11-0.14 mm. 



The types of this species are from the Pleistocene of Timms Point, 

 California. Typical specimens occur at numerous stations off the coast, 

 as follows:
