Original description: [First segment campanulate (including the cephalis without stricture ?). Second segment, separated by a slight stricture, a porous membrane passing into numerous, contiguous, truncate laminae. Pores separated, in quincuncial rows. Total length 72 µ, of the first segment 37 µ. Approximately 5 pores in 23 µ.

Related to C. polypterae from Zanzibar, but a different form with appendages hidden by a porous membrane. (Translated from Latin by E.M.R. and W.R.R.)]
