Original Description

The number of pores (about 13 in the transverse row), the shell outline with the small velum, and the dimensions are the same as in C. bicornis (Popofsky). The distinguishing characteristics are the pronounced "shoulders" and thickened part of the thorax (Plate 15, Figure 7).

Etymology:
Species name means "shoulder."

Extra details from original publication
Distinguishing characters: It is very similar to the "shoulders" of the Paleocene species (Plate 15, Figures 18-20), but C. humerus has more pores. It is difficult to say if the shoulders may originate in different branches of Clathrocyclas independently (in parallel way), or if the two species, the Paleocene and C humerus are closely related.

Editors' Notes
The description is based on 46 specimens from Site 278 (Cores 12-30).
