386 TORNATELLID A. 
indigena, 7. littorea, T.Grayana?, and T. nitidissima ? are never 
truncate at the apex; still, this appellation has been so long 
established, that it is better to continue it than add new names 
to science :—the latter remarks are M. Philippi’s sentiments. 
We have here a striking illustration of the value of céncholo- 
gical-made genera, since, in consequence thereof, three species 
of one genus have received as many generic titles, from their 
shells exhibiting a subcylindrical, a conical, and (if the 
Skenea? nitidissima of authors is the T. atomus? of Philippi, 
as is probably the case) a discoid form. 
I see no reason to doubt M. Philippi’s Truncatella littorina 
(Moll. Sicil. vol. u. p. 133, tab. 24. fig. 2) being our present 
species ; the description and figure entirely accord.

This, probably, is M. Philippi’s species; it is placed provi- 
sionally, until some of the Scotch naturalists have supplied 
notes on the animal, which is abundant on their coasts. It is 
also taken in Ireland. 
Since the above remark, we have examined our specimens, 
which fortunately proved to have been taken alive, and find 
that the operculum is precisely of the same grossly spiral 
character and sculpture as in Truncatella Montagui and T. lit- 
torea; moreover, the eyes in the dried animal are perfectly 
visible, and show the characteristic white pupil of what may 
now be safely termed its congener.
