species; wall thin, composed of fine sand with more or less chitin; 

 apertures several to many at the end of nipple-like protuberances of 

 the surface, occasionally wanting. 



Two species occur rarely in the North Pacific; the third species, 

 described by Goes, does not seem to be a Foraminifer as far as can 

 be made out by a study of Goes's material.

 (in text). 



Description. — Test usually free and rounded, occasionally adherent, 

 the lower surface being adapted to the shape of the object to which it 

 is adherent; usually a single chamber, but occasionally another cham- 

 ber is found within the outer one; wall very thin, composed of small 

 ^^ sand grains very neatly cemented with 



a reddish-brown cement, giving the

ing length. 



Diameter 0.4-1.6 mm. 

 Distribution. — All that is known of this 

 species in the North Pacific is from the 

 Challenger dredgings, stations 237, 246, 

 253, 269, in 1,875, 2,050, 3,125, and 2,550

stations is a short distance east of Japan, 

 the others in the deep water of the mid-Pacific. It also occurred at 

 station 271, just south of the equator, in 2,425 fathoms. 



From the figures and description there is evidently more than one 

 thing now included under this specific name, but more material is 

 necessary to be sure of this.
