Catalog entries: Buryella clinata

Original description: Shell of four segments, with none of the strictures expressed externally. Cephalis subspherical with a few very small circular pores, bearing a broad-based, sharp, bladed, apical horn, its length up to twice that of the cephalis. Ridges from the horn diverge and extend to the collar stricture except ventrally where two ridges rejoin to enclose a vertical pore and form an upwardly directed tube. Collar stricture internally with four collar pores. Thorax truncate-conical with circular pores randomly or quincuncially arranged. Third segment largest, inflated, its greatest dimension medianly or in the distal half, with circular to subcircular pores, quincuncially arranged in transverse and diagonal rows. Fourth segment inversely truncate-conical proximally, cylindrical distally with thinner wall, and pores subcircular to elliptical in transverse rows, termination ragged.
