An interesting form, giving a hint about the origin of the smooth forms of 
Nodosarina, particularly of N. pauperata D'ORB., of which it should be con- 
sidered as an allied form. It attains large dimensions, 17-22 mm. in length. 
The septa are somewhat thickened, but not exactly limbate in our form. 
Caribbean Sea. 300 fathoms (Goés).

In the form and. arrangement of the segments it differs very little from N. 
soluta Ruuss ; the surface is very faintly striated, but the maturer segments are 
more or less smooth.

Seems to be very rare in the course of the ** Albatross” cruise, a couple of 
specimens only having occurred in the Pacific, In comparison with specimens 
from. tertiary deposits the recent form is usually a pygmy. 
Pacific. 730 fathoms ; scarce.
