Description. — " Volutions cancellate, the transvere costse eleven, ro- 

 bust; revolving lines filiform, irregularly alternately smaller, creniilating 

 the edge of the exterior lip, which is acute, and alternating with the raised 

 lines of the fauces; fauces tinged with chocolate colour; heah short, ob- 

 tuse, not rectilinear; lahruni not incrassated." Say, 1822. 



The fossil which is here referred to cinereus often differs considerably 

 from the typical specimens of that form in proportional length, character 

 of sculpture, and straightness of beak ; but it nevertheless grades into it 

 so that a consistent separation is impossible. On the other hand the sejja- 

 ration from its stratigraphic associate, U. rustica, though sometimes diffi- 

 oult, is much more distinct.
