 pressed, also basally when uouble-apertured ; irregular in out- 

 line ; composed of sand-grains and tests of other Foramin if era, 

 as Globiqerina, cemented to a brown chitinous base or in- 

 ternal lining. Aperture more or less circular. 



Dimensions. — About 0*8 mm. in diameter. Aperture about 

 028 mm. across. 



This species reminds one of Proreonina di(fi naif omits, 

 Brady sp., var. tcstacea, Flint," in its general appearance. 

 It differs morphologically, however, in having a cylindrical 

 cavity instead of an inflated chamber.

Only two specimens of this widely distributed form occur in 

 our series. The test, in each example, is formed of loosely 

 cemented sand-grains. One specimen has a blunt termina- 

 tion, whilst the other gradually tapers to a point.

 colour, and their texture somewhat coarsely arenaceous. It 

 is a widely distributed form in recent deposits.
