inflated, and delicately marked with numerous, impressed, 

 revolving lines ; aperture extending the whole length of the 

 shell, very narrow behind, and rapidly widening forwards, 

 p. lineo- so that the lip is broadly rounded in front ; the pillar has a 

 faint oblique fold near the middle. AVithin glossy, yellow- 

 ish-white. Length, three twentieths of an inch ; breadth, three 

 fortieths of an inch. 



Several specimens of this very delicate and very singular shell 

 have l^een taken from the stomachs of fishes caught in Massachu- 

 setts Bay ; Cape Cod northward to Grand Manan ( Stimpson) ; Fish- 

 ing Banks, rare Q Willis). 



It appears like a diminutive specimen of Bulla lig-ncma, but its 

 somewhat elevated spire is one good distinctive mark. The revolv- 

 ing lines are rather distant, regularly disposed, and always conspic- 

 uous under a magnifier.
