Figs. 1, 2. Two v-iews of a slightly compresseil cast of an imperfect specimen, showing the expansion, and the 

 general charactere of the species. 



Figs. 3, 4. The opposite sides of a lai'ger cast, somewhat compressed, showing a more gradual tapering 

 form, with the deeply concave septum truncating- the apex. 



Figf. S. From a gutta-pereha impi-ession in the natural mold, the specimen showing a rapidly tapering shell, 

 as in figui-es 1 and 2, with crowded stria' at the lower extremity. The surface is marked by the 

 imprints of several DlsciNA which have been attached to the surface. It is possible that further 

 examination, with a larger number of specimens, may prove the form shown in tigui'es 1, 2 and 

 6 distinct from that of figures 3 and 4. 



Fig. 7. A diagram giving the form of a transverse section of the specimen fijfures 1 and 2.

Pig. 8. A fragment in shale, showing a very gradual expansion of the cone, and very fine cvowded ti-ans- 



vei-se strije. 

 Fig. 9. Enlargement of the surface, showing the transverse stHse apparently destitute of nodes. This 

 appearance may be due to partial exfoliation of the shell.
