FORAMINIFERA OF THE ATLANTIC OCEAN. 69 



Description. — Variety differing from the typical in its smaller size 

 and hispid surface made up of a great number of sponge spicules 

 arranged nearly perpendicular to the outer surface. 



Diameter, usually not exceeding 1 mm. 



Distribution. — Flint gives four Atlantic stations for this variety, 

 Alhatross D2570, 2571, 2379, 2394, in 420-1,813 fathoms, two of them 

 south of Georges Bank, the other two in the northern part of the Gulf 

 of Mexico. Besides this material I have but one station to add, 

 D2203, south of Georges Bank, in 705 fathoms, bottom temperature 

 38.9° F. Flint also records it from the coast of Oregon in the Pacific, 

 D3080 in 93 fathoms. 



Pearcey's notes in his Antarctic paper are as follows : 



One specimen larger than the type attached to a rock fragment at station 420 (2,620 

 fathoms) [Antarctic]. Walls built of sponge spicules arranged perpendicularly in an 

 amorphous siliceous cement and lined interiorly with a delicate chitinous membrane. 



He also notes that the variety was taken by the Triton and Knight 

 Errant Expeditions in the Faroe Channel and "recorded by me under 

 the generic name of Sorosphaera sp., with several others of a similar 

 character." 



This is a rather definite variety and can hardly be mistaken for 

 anv other.

 (in text). 



Description. — ^Test free, sublenticular, subglobose or oblong, occa- 

 sionally roughly polygonal, slightly roughened; wall composed of sand 

 grains with a few sponge spicules irregularly incorporated, loosely 

 cemented, somewhat friable, interior with irregularly filled space, 

 intercommunicating; apertures numerous, many scattered small ones 

 with a few larger ones more or less grouped together. 



Diameter, up to 2 mm.; length, up to 4 mm. 



Distribution. — Goes described this species from the Skagerack in 

 300 meters, Schaudinn had it from off Bergen, Norway. Our 

 western Atlantic material does not seem to be identical with this 

 species. 



CRITHIONINA GRANUM Goes, var. SUBSIMPLEX Goea. 



Crithionina granum Goes, var. suhsimplex Goe.s, Bull. Mus. C'omp. Zool., vol. 29, 

 1896, p. 25.— Rhumbler, Arch. Prot., vol. 3, 1903, p. 232. 



According to Goes the form is described as follows: 



Resembles in shape the type, but the walls are thin and the subdividing lamina 

 of the cavity very much reduced, sometimes nearly obsolete.
