Original description: Wide conical-campanulate shell having a flat marginally shouldered abdomen; apical horn terminal, single, rod like (distally broken), and basally simple; cephalis subhemispherical, short (less than 0.14 total length), and with the cervical stricture marked by change in lateral contour (its basal diameter little greater than the length); thorax generally and widely subconical (75°), with mild asymmetry, and swelling near the middle, the basal diameter great (0.73 total length), and the length equal to the basal diameter; abdomen wide, generally ringlike, around the base of the thorax with sharp stricture (lumbar), and distally bending rather suddenly to form a short circular rim (about the same in height as the cephalis), the free edge of this rim much torn so that the marginal teeth presumed to be present are lost; pores of cephalis few (not more than 16), well separated, and small (2.2?m or less); pores of thorax generally graded from small at the neck to large at the base with a few odd tiny ones subcervically, generally subelliptical or even subpolygonal especially above the base, rather closely set, and comparatively numerous (over 100); pores of abdomen in 3 transverse rows which are fairly regular (more so than in the thorax), and 1 row is along the rim; wall generally hyaline.
Remarks on original description: The authors here list Clathrocyclas aurelia under the subgeneric name Clathrocycloma and include the subgeneric name in the species name.[comment from RadWorld database]
