possession resembling it in every respect, with the exception of the columella, which in 
his specimens had three, and in one instance four folds, denoting it to be a true A/ira. 
I have, therefore, retained for it the above name. It much resembles, and probably may 
be the same as, Voluta pyramidella of Brocchi, p. 318, Tab. IV, fig. 5; my sheil has 
an obtuse apex, the volutions much flattened, a very slight shoulder, and a deep 
suture. Mr. Bell gives J/. ebenus as a Red Crag shell from Waldringfield, but I have not 
seen the specimen.

A single specimen of a shell, which I have with very little doubt referred to a common 
Continental fossil species, has been obtained from the nodule workings by the Rev. Mr. 
Canham. ‘This specimen has, like many of its associates in the Red Crag at Waldring- 
field, undergone some rough treatment. Most of its outer coating has been removed. 
It is a very elongated specimen, but I believe where it is abundant the same form may be 
observed. Our, specimen has only four folds upon the columella; the first is the most 
prominent, diminishing towards the base, but these plaits or folds are said to vary in 
number from four to six. This is probably a derived specimen. 
In vol. ii, ‘Moll. Sic.,’ Phillippi refers JZ. fusiformis to M. zonata, Swainson and 
Risso. Weinkauff gives this name to Marryat. ‘This latter name seems to have been 
imposed on the existing shell from the coloured band on the exterior. I have retained 
Brocchi’s name, which seems to be generally adopted for this fossil. It is a variable 
species, and Bellardi assions as synonyms Jf. plicatella, Lam., 47. pyramidella, and 
M. incognita, Grateloup.
