180 Couthouy’s Descriptions of 
Ozsenvations. This little shell was taken from the 
stomach of a haddock, caught in October last, in about 
twenty-five fathoms water, off Race Point. At the first 
glance, it looks much like a diminutive specimen of B. 
lignaria, Linn., both in its outline and by its numerous 
oblique striz. It is, however, very distinct from that 
species in any stage of growth, in having an obtusely 
. prominent spire, instead of discoidal or sub-umbilicate. 
A single specimen only has been met'with, which, 
though. only of the size here given, has every appear- 
ance of an vm shell. `

Description. Shell globular, minute, very thin and 
brittle, hyaline, with a brownish tinge, except near the 
lip where it is whitish; body whorl enveloping all the 
rest so as to leave no perceptible spire, and covered with 
very delicate incremental strie ; the aperture is narrow 
for a short distance from its upper extremity, but is 
greatly dilated toward the base ; the outer lip is very 
strongly and regularly curved ; the columella slightly 
arcuated and reflected upon the body of the shell, so as 
to form a very small but distinct umbilicus. 
Length one-tenth of an inch, breadth about the same. 
Inhabits the waters of Massachusetts Bay.
