In the outlines the West Indian form is rather Marginulina-like, with strong 
raised and often beaded septa, sometimes the beads growing to short spines, 
particularly on the early segments, which often are carinate and their margins 
provided with spines. Our form seems to have narrower and more closely fitted 
chambers than the specimens designed by Brady. Length about 2.30 mm. 
Caribbean Sea. 200 fathoms. 
ALLIED Form :— 
C. ensiformis Goks. 
The representation on our Plate V. Figs. 17, 18, is a more seldom met 
with smooth variety, with quite Marginulina-formed outlines, resembling 
Marg. ensis Reuss, its close affinity to C. aculeata shown only by inter- 
mediate forms and the marginal spines of the early stage, those spines being 
sometimes nearly obsolete. Length about 3mm. 
Caribbean Sea. 196-210 fathoms.

This form is not very rare in moderate depths of the tropic seas, although it 
has been scantily met with in “ Albatross” dredgings. It assumes a lot of 
varietal forms, being impossible to define it on one side from Vaginulina levigata 
Roem., and on the other from C. rotulata Lock.
