8 SUPPLEMENT TO THE CRAG MOLLUSCA. 



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 Mitra. 

 I have, therefore, retained for it the above name. It much resembles, and probably may 

 be the same as, Voluta pgramidella of Brocchi, p. 318, Tab. IV, fig. 5 ; my shell has 

 an obtuse apex, the volutions much flattened, a very slight shoulder, and a deep 

 suture. Mr. Bell gives M. ebenns 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 M. 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 assigns as synonyms M. plicatella, Lam., M. pgramidella, and 

 M. incognita, Grateloup.
