FORAMINIFEEA OF NORTH PACIFIC OCEAN. 35 



Distribution. — The only previously recorded station for this species 

 in the North Pacific is Albatross station D3375 in 1,201 fathoms in 

 globigerina ooze southwest of Panama. Goes' s material consists of 

 six specimens from this station. Some of them are not this species 

 but belong evidently to Pelosina cylindrica H. B. Brady. Frag- 

 mentary material referred to this species has been noted in the sam- 

 ples from three Nero stations between Midway Island and Guam, 

 Nos. 172, 1583, and 1678, in 2,086, 777, and 1,283 fathoms, respectively, 

 all in globigerina ooze. 



Subfamily S. SACCAMMINlN^]. 



Test consisting of a single chamber, or group of superficially at- 

 tached chambers, the walls made up for the most part of agglutinated 

 material; apertures sometimes numerous but usually single; tests 

 free or attached. 



Included here are a number of genera which seem to have certain 

 common characters; that of a test of agglutinated material of a single 

 chamber, usually with a single opening. The wall may be greatly 

 varied in its constituents in the various genera, being composed of 

 sand grains in Proteonina, of a single layer of sponge spicules in 

 Technitella, of a felted mass of spicules in Pilulina, or of other tests, 

 etc., in Pelosina cylindrica.

Description. — Test free or attached, usually spherical, no definite 

 aperture, the pseudopodia making their way out between the ele- 

 ments of the test ; wall composed of sand grains or other loose material 

 cemented together. 



Two species of this genus occur in the North Pacific, but both of 

 them are rare and have been found at but few stations.
