BULLA acuminata, 
TAB. CCCCLXIV- fig. 5. 
Sfec. Char. Cylindrical, transversely striated ; 
vertex acuminated ; aperture linear. 
Three and a half times as long as wide ; at first sight 
much resembling the Volvariae, but the base of the aper- 
ture is more expanded, and it has no plaits : the stride 
are not dotted, they are obscure near the middle of the 
whorl ; the superior edge of the aperture is produced to 
a point. 
Sent from Hordwell or Barton by Miss Beminster.
