This is a somewhat aberrant variety of the elegant Nodosaria 

 described by Reuss, differing chiefly in its larger growth and irregular 

 costae. The typical form is generally distributed through the Upper 

 Cretaceous.

It is difficult to satisfactorily separate certain of the cristellaroid 

 forms found in the Lias, Cretaceous, and Tertiary formations, for 

 they run so insensibly into the Vaginulina type of shell, which is 

 flattened laterally, and has the commencement practically non-spiral. 



The above species has likewise little or no spiral at the commence- 

 ment of the shell, and therefore it appears more properly to belong 

 to Vaginulina. The specific form here referred to is like a broad 

 V. legumen with few chambers and a superficial sutural thickening 

 or limbation. V. humilis seems to be restricted to the Neocomian 

 and Gault strata of Germany and England. Somewhat rare in the 

 Cretaceous of East Pondoland.
