Radial plates more rapidly expanding, giving a sliortturbinate aspect to the upper part of the body, contracting to-wards their superior margins, which are more or less abruptlybent inwards; the upper margins marked by two narrow grooves,for the insertion of the next series of plates. Surface smooth or finely granulose-striate. The specimens which I have examined are about an inch and a half inlength, from the base to the smnmit of the radial plates. One specimenpreserves a fragment of a single plate of the third series, but too im-pertect to be of any value in determining the form. The base
