BULLA atteiiuata. 



TAB. CCCCLXIV.-^^. 3. 



Spec. Char. Elliptical, transversely striated ; 

 superior portion elongated, truncated, per- 

 forated; aperture curved, widest towards 

 the base ; striae distant in the middle. 



About twice as long as wide ; the striae upon the upper 

 elongated portion are close and deep; those on the 

 middle of the whorl, slight and distant ; upon the base 

 they are numerous, but not very strong. 



Figured from a specimen from Hordwell, in the Col- 

 lection of Miss Bennet ; a small specimen has also been 

 »ent by Miss Beminster. 



Bulla filosa. 

 TAB. CCCCLXIV— >'^. 4. 



This is a mutilated specimen of a large Bulla, that 

 is very finely striated ; we propose to name it Bulla 

 FiLOSA, and regret much that we have never met with a 

 specimen, from which a Specific Character can be drawn 

 up : its numerous striae and expanded lip, distinguish it 

 from B. attenuata.
