distant, revolving, sometimes undulating stria? ; apex circularly 

 and deeply excavated, columella sinuose, broadly 

 '°' ' and liglitly callous ; lip crenulatcd posteriorly ; ap-

Several specimens were taken from fishes caught 

 on the " Middle Bank," in seventeen fathoms ; in

 Philine lineolata, Stijipson, Check Lists, 4 (18G0). 



Shell very small, oblong-ovate, broadest anteriorly, very thin, 



and fragile, covered with a thin, rust-colored epidermis; whorls 



three, forming a flattened spire, the outer one somewhat 



^'^' ^°*' inflated, and delicately marked with numerous, impressed, 



revolving lines ; aperture extending the whole length of the 



shell, very narrow behind, and rapidly widening forwards, 



so that the lip is broadly rounded in front ; the pillar has a 



faint oblique fold near the middle. Within 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 been taken from the stomachs of fishes caught in Massachu- 

 setts Bay; Cape Cod northward to Grand Manan {Slimpson) ; Fish- 

 ing Banks, rare (Willis}. 



It appears like a diminutive specimen of Bulla lig-naria, 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.
