Test elongate, subcylindrical, often somevi^hat tapering toward the 

 apertural end, straight or nearly so, composed of a rather large globular 

 proloculum and elongate cylindrical or slightly tapering second cham- 

 ber slightly less in diameter than the proloculum; vi^all thick, loosely 

 cemented especially on the exterior, rough, composed usually of fine 

 sand, sometimes mixed with coarse sand particles, occasionally with a 

 varying amount of sponge spicules, interior commonly smoother, with a 

 yellowish-brown cement; aperture circular, at the distal end of the 

 second chamber. 



Diameter, 2.00 mm; length, up to 10.00 mm. 



There is a considerable amount of variation in the material of which 

 the test is made, undoubtedly depending much on the character of the 

 bottom. Some of our specimens have a considerable proportion of sponge 

 spicules included at certain stations and this is shown in our figured 

 specimens. 



Localities: 415, 487, 447, 2026. Specimens are abundant at 447. 



Distribution. — Off Guadalupe Island, Mexico, in 200 fms. ; outside 

 of Concepcion Bay in 30 fms. and in Fraile Bay, in 10 fms. Lower Cali- 

 fornia, Mexico; off the Galapagos Islands, in depths ranging from 32 

 to 400 fms., with an abundance at Cartago Bay, Albemarle Island, in 

 32 fms.
