FORAMINIFERA OF NORTH PACIFIC OCEAN. 69 



This species is characterized by an irregular form in the biserial 

 portion, one or more of the chambers breaking the alignment some- 

 what and causing the following to be less regular than they would 

 be otherwise.

Description. — Test compressed, broad, gradually tapering to the 

 broadly rounded initial end; triserial portion consisting of but few 

 chambers; biserial portion compressed, making up most of the test; 

 chambers rounded; wall of fine arenaceous material; the surface 

 smoothly finished; aperture an elon- 

 gate slit slightly in from the inner edge 

 of the chamber, surrounded by a 

 slightly thickened and raised lip; color 

 gray. 



Length about 1 mm. 



Distribution. — Goes records this spe- 

 cies from Albatross station D3407, in 

 885 fathoms, off the Galapagos Islands.

pears to be tins species upon exami- 

 nation. Egger's figure and description are apparently meant for this 

 species, but do not fit it very closely. I have seen but one specimen 

 which I can refer to this species, from the coast of Japan, Albatross 

 station D4916, in 361 fathoms.

 Rep. U. S. Nat. Mus., 1897 (1899), p. 2S8, pi. 34, fig. 2. 



Description. — Test elongate; triserial portion consisting of few 

 chambers, forming usually somewhat less than half the test; later 

 portion biserial, the chambers inflated and distinct, the later cham- 

 bers with a forward extension, at the end of which is the aperture; 

 wall rather coarsely arenaceous and slightly rough; aperture nearly 

 circular, at the end of the elongate chamber; color reddish brown. 



Length up to 1 mm.
