set together. Under a fairly high magnification, these costse appear 

 to be built of minute sand-grains and are of a light brown tint, 

 showing up well against the dark background. The test is thin, 

 and the under-surface is not so thickly covered with the same 

 decoration. As far as I can tell from the inferior surface, the test 

 has probably six or seven chambers in the final whorl, but the 

 coiling of the chambers does not show on either surface. Two 

 specimens occur.

Both the Megalospheric and Microspheric forms occur; the 

 former having a large, oval, initial chamber, and the latter a much 

 smaller, generally rounded chamber, highly domed. The tube 

 of the Microspheric form is sinuous, and has a Globigerina shell 

 attached in the hollow of each curve. This tube is much stouter 

 than in the Megalospheric form. 



A single white specimen occurs, which is in the Megalospheric 

 condition.

Several varieties occur. In one variety the initial chambers 

 have acute edges, this acuteness being lost as the test broadens out 

 and thickens.
