The Soldanian drawing, which serves as the basis of the present species, represents 
a long, slender, slightly bent, Nodosarian shell, with numerous short oval segments. The 
segments are more distinctly oval and more regular than those of the specimens figured in 
PI. LXIII., which are not good illustrations of the typical form. 
Nodosaria Jiliformis has been collected both in the North and South Atlantic and in 
the North and South Pacific, at depths ranging from 50 to 450 fathoms, but typical 
examples are by no means common. 
In the fossil state it is met with as far back as the Lias, and is found associated with 
its congeners in many subsequent microzoic formations.

The test of Nodosaria pauperata is described by d’Orbigny as short and stout, slightly 
arched, smooth externally, and formed of chambers of nearly equal size ; the 
earlier segments not projecting externally, the later ones convex and separated by deep
