Balea peregrina, Goutp; Proceed. Boston Soc. Nat. Hist., u. 197. 
March, 1847. Expedition Shells, 34. 
SHELL reversed, small, solid, elongated, somewhat fusiform, blunt 
at the tip, with a few irregular, longitudinal strie, seldom entirely 
crossing a whorl, and of a dead ashy-brown colour. There are eight 
whorls, of which the two preceding the last are the largest and flat, 
while those near the apex are rounded: they are all a little shouldered 
and separated by a linear, deeply-impressed suture. The aperture is 
longitudinal, somewhat four-sided, with rounded angles; the peristome 
is continuous, rising up to a level with the surface of the shell, and a 
very little reflexed. ‘The columellar side is highly raised in front of a 
well-developed umbilicus. 
Length three-eighths of an inch ; breadth one-tenth of an inch. 
Inhabits New Zealand. 
I have referred this shell to the genus Bal/ea with much hesitation, 
on account of its locality. It is remarkable for its fusiform, turreted 
shape, and for the high walls of its aperture, which rise to a level with 
the surface of the shell.
