SOME NEW DEVONIC FOSSILS IQI 



of body whorl sharply carinate or even extended into a keel or 

 flange which seems to carry a slit band. Aperture sharply angu- 

 lated exteriorly, subcircular in outline, thickened and slightly ex-

based only on the resemblance of the internal casts of the two 

 shells for of the exterior of the latter we have as yet no definite 

 knowledge. It is instructive to observe that the Spiriferensandstein 

 of the Oberharz (Bocksberg) carries an Eotomaria of similar style 

 with extended peripheral flange [Pleurotomaria kleini

 pi. I, fig. 10], though a shell of much larger type than that here
