As already explained in the notes upon Nodosaria farcimen, the description and 
figure furnished by d’Orbigny, in his memoir on Foraminifera of the White Chalk of the 
Paris Basin, constitute the best basis for the present species (p. 499). 
In the classification of the smooth-shelled Nodosarians into varietal or quasi-specific 
groups, by characters derived from the shape and mode of combination of the chambers, 
Nodosaria communis affords the best type of the slender arcuate forms with oblique 
segments. Besides the Cretaceous examples above referred to, good typical specimens 
of this sort are figured by d’Orbigny in the “ Vienna Basin ” monograph, as Dentalina 
inornata and Dentalina badenensis, and by Williamson as Dentalina subarcuata. 
The foregoing list of synonyms appears somewhat lengthy, but it might have been 
greatly increased without infringing the morphological limits of a moderately restricted 
varietal group. 
Nodosaria communis has the same world-wide distribution as the closely allied 
Nodosaria farcimen, and a similar geological range.

This form occupies very much the same position amongst the curved Nodosaria 
with obliquely-set chambers, that Nodosaria pauperata holds amongst those with 
straight sutures. The test is short and stoutly built, cylindrical and slightly bent, and 
the primordial end is rounded. The earlier segments are close-fitting, and the septa are 
marked by oblique lines without external depressions ; the later segments are more or
