82 SUPPLEMENT TO THE CRAG MOLLUSCA. 
Conchology,’ however, insists that this Crag shell is distinct from the hving papillosus 
(granulatus). 
In ‘Supplement, Tab. V, fig. 14, I have shown a specimen from Walton Naze, which 
represents another of the various forms of this shell, and which in its granulations seems 
undistinguishable from the recent papillosus, but is much flatter, and without any 
convexity in the whorls. Under these circumstances I have thought it best provisionally 
to place the shell shown in the above figure, and in figures 6, a, 6, c, of Tab. XIII of 
‘Crag Mollusca,’ as a new species under the name zoduliferens. 
Whether 7 granulatus, from Walton Naze, in Mr. Bell’s list (‘ Annals and Mag. Nat. 
Hist.,’ September, 1870), presents any nearer approach to the living shell I know not, as 
I have not seen the specimen. 
Dr. Woodward gives Trochus granulatus, Born (similis Sby.), in his list of 
Norwich Crag shells in ‘ White’s Directory,’ as from Bramerton and Thorpe, on more 
than one authority. But whether the recent granulatus, or the above shell now called 
noduliferens is meant I am unable to say. 
Fragments of a granulated Trochus occur in the Middle Glacial of Hopton that may 
belong either to this shell or to papillosus (granulatus).

The specimen figured in ‘Suppl.,’ Tab. VII, was obtained by me some years ago 
from the Reg Crag of Walton. It differs altogether from zizyphinus in the tumidity 
of the whorls and in the presence on them of faint granulations (which, however, rather 
resemble diagonal sculpturing than granulations), and m these particulars the shell seems 
identical with the figure and description of Phihppi’s species Jézd/atus. 1 have 
also a half-grown specimen from the same locality. ‘The shell figured in ‘Crag 
Mollusca, Tab. XIII, fig. 4, as zvzyphinus var. monstrosa, from the Coralline Crag, 
Sutton, appears to be the same species, and Mr. Bell observes ‘Ann. and Mag. Nat. 
Hist.,’ May, 1871, that “he has obtained two specimens, one decorticated (similar to 
the shell figured in the ‘Mon. Crag Moll.,’ Tab. XIII, fig. 4), from the Cor. Crag, Gedgrave, 
and that Prof. Sequenza had sent hima series of Philippi’s 7 du//atus in all stages of growth 
and preservation, and a close comparison of their sculpture and form enabled him to 
correlate the Italian and Crag shells.” Mr. Bell showed me the series thus obtained, and, 
as it seemed to bear out the view thus expressed, I have inserted the species from both the 
Coralline and Red Crag.
