Descriptions
The shell is ovoid, circular in transverse section and composed of approximately one hundred, circular, shell-plates. About twelve shell-plates surround the aperture and project only slightly from the following row of overlying shell-plates. The remainder of the shell-plates are arranged in a regular manner. The aperture is circular and is bordered by a collar of organic material, from which tooth-like structures usually project. The organic collar is not completely preserved in some specimens, and in these cases the tooth-like projections are absent. Cash et al. (1915) observed that the collar was often difficult to see, and that it was sometimes absent. They also figured variations in the shell-plates from circular to oval. (ref. ID; 3686)
Measurements
Shell length 52-61, width 29-31; diameter of aperture 8.8-11.5; diameter of shell-plates 6.6-8.8 um (n=6). (ref. ID; 3686)
