Locality. Coralline Crag, Sutton. 
Very recently I have found two or three specimens which I believe may be fairly 
referred to the above-named species. ‘They were obtained too late to be represented in 
my plate. 
PLEUROTOMA STRIOLATA, Philippi.

Locality. Coralline Crag, near Orford. 
Since my plates were engraved for this work, Mr. Robert Bell has shown me a 
specimen from near Orford with the above name, which I believe is correctly referred, and 
more recently I have obtained a similar one from the same locality.

Locality. Corallme Crag, Gedgrave. 
T'wo specimens of this species have been obtained by Mr. A. Bell and sent tome with 
the above name. They differ slightly from the general form of conforta in being rather more 
elongated, corresponding with what Dr. Hornes has considered a variety (fig. 8 of his plate), 
which has comparatively a smaller and shorter aperture, that is less than the length of the 
spire. It has about sixteen longitudinal ridges, crossed by spiral striz, alternating large 
and small, and the outer lip is strongly denticulated. It is an elegantly formed shell, and 
not at all appropriately named. Having had no other means of identifying this than 
figures, I have given the reference with doubt.
