Constrictions between the segments are equal to or less than those in C. languncula. There are a few short spines on the thorax as well as on the basal side of the last chamber. Four to five abdominal ribs attached on the wall and extending out of the last chamber and become feet which are as long as the chamber's length and slightly curved inward. Pores circular and small in the thorax and gradually increase their size and become hexagonal toward the last chamber. The last chamber's pores are as wide as 2-3 times the thickness of interporous bars.
