26 SUPPLEMENT TO THE CRAG MOLLUSCA. 
he tells me has been determined by Mr. Jeffreys to belong to the above-named species ; 
the label accompanying the specimen says, “ once marked Guwnaneri by 8S. P. W.” In the 
Appendix to the ‘ Crag Mollusca,’ p. 313, Tab. XXXI, fig. 4, is described a shell from 
the neighbourhood of Wexford which had been previously considered by EH. Forbes 
(‘Mem. Geol. Surv.,’ 1846, p. 425) as Zrophon Fabricti, Moller, with the name of 
craticulatus, Fab., given by Méller as a synonym. ‘The shell I have here figured is 
probably the same species, but it is different in some of its characters, and I have in 
consequence had it represented as a variety. ‘The exterior is ribbed and decussated by 
two or more raised spiral ridges, but it has not the upper part of the volution projecting 
and fimbriated. I believe in the assignment, and have adopted the above name as being 
the older one, on the authority of Moller. This name must, therefore, be given to the 
figure in the ‘ App. to Crag Moll.” Fusus craticulatus, Broc., is a very different shell.

The figure of this shell was taken from a specimen from the Clyde beds, and was 
introduced in order to show the difference from the next species (figs. 10 @ and 4), but 
since the plate was engraved I have seen a suite of specimens from the post-glacial gravel of 
March ; so that this species is an Hast Anglian fossil. The March specimens are rather 
larger than any that I have seen from the Clyde beds, and approach slightly nearer to 
scalariformis. A specimen of Bamfius was sent me for examination by Mr. G. Maw, from 
the Severn Valley beds. Ihave not met with this species from the Crag or any Hast 
Anglian glacial bed. It is given under the name clathratus by Mr. J effreys from Kelsea 
Hill. 
TROPHON SCALARIFORMIS, Gould. Crag Moll., vol. 1, p. 48, Tab. VI, fig. 7. Supple- 
ment, Tab. III, fig. 10 a, 6. 
Localities. Red Crag, Sutton, Bawdsey, Butley. Fluvio-marine Crag, Bramerton. 
Middle Glacial, Billockby and Hopton. Upper Glacial, Bridlmgton. Post-glacial, 
Kelsea Hill. 
The figure is taken from a Bridlington sltell belonging to Mr. Leckenby, which seems 
to have been the authority for the occurrence of Bamfius at Bridlington. The shell, 
however, seems to me not to belong to that species, but to be the young of the much 
larger Crag shell, sealariformis (‘Crag Moll.,’ Tab. VI, fig. 7), which (identical in size 
and in all other respects with the Crag shell) is common at Bridlington.
