for the species is from foraminiferal sand dredged 16 miles east of 

 Wollongong off Australia, at a depth of 100 fathoms. In our present 

 collections the species has occurred as single specimens at two Alba- 

 tross stations as follows: H3989, South Pass, Likieb, ji mile north, 468 

 fathoms, 42.6° F., crs. co. s. (U.S.N.M. No. 26731); and H3983, 

 entrance to South Pass, Rongelap, ji mile north, 400 fathoms, 43.4° 

 F., CO. s. (U.S.N.M. No. 26732).

Test elongate, subcylindrical, very slightly compressed, initial end 

 rounded; chambers numerous, high, very slightly inflated; sutures 

 distinct but not depressed; wall hyaline, the lower half of each chamber 

 with rather coarse foramina, the upper half clear; aperture elongate, 

 loop-shaped; transparent except the lower half of each chamber, 

 which is whitish. Length, up to 1.00 mm. 



The original references for this are from the cold waters of the 

 North Pacific as are also the other records. It occurs also in the late 

 Tertiary of California. Specimens apparently identical with this 

 species occur in our present material only at tlu-ee Albatross stations 

 in the eastern part of the area.
