22 SUPPLEMENT TO THE CRAG MOLLUSCA. 
‘TROPHON vENTRICOSUS? Gray. Supplement, Tab. III, fig. 4. 
Fusus ventricosus, Gray. In Beechey’s Voyage, p. 117. 
= — Gould. Inv. Massachusetts, p. 285, fig. 200. 
Locality. Upper Glacial, Bridlington. 
The specimen figured was sent to me by Mr. Leckenby ; it is not perfect, and unfit for 
fair description, but I have doubtfully referred it as above. Dr. S. P. Woodward intro- 
duced this name in his list of Bridlington species, depending for so doing upon the 
above-mentioned specimen, as I have done. 
Tropuon Turtont, Bean. Crag Moll., Appendix, p. 312, Tab. XXXII, fig. 2. Supple- 
ment, Tab. I, fig. 11, a, 4. 
Locality. Red Crag, Butley and Waldringfield. 
In the ‘Crag Moll., vol. ii, p. 312, I was able to indicate the presence of this» 
species in the Red Crag, but my specimen there illustrated (Tab. XXXI, fig. 2) was so 
fragmentary that it could not be depended upon, and although the specimen I have had 
figured is not quite perfect it is sufficiently so to justify me in referring it to the species - 
above named. Since my specimen was engraved I have seen, in the collection of the Rev. 
Mr. Canham, an individual of this species obtained from the nodule pit in the Red Crag 
at Waldringfield, rather larger than my own, with the aperture more perfect, as also 
another by Mr. Bell, from Butley; one of these I should have preferred to have had 
figured had I been previously aware of their existence. 
TRopHon ELEGANS, Charlesworth. Crag Moll., vol. i, p. 46, Tab. V, fig. 2. 
In Mr. Canham’s rich collection of Crag fossils is a fine specimen of what has been 
figured under the name of Trophon elegans, Charlesworth. The locality was not then 
known, and it is somewhat singular that this second individual should also have been 
picked up on the beach at Felixstow. Fig. 6, a, 6, Tab. I, represents a shell found in 
the Red Crag at Butley by Mr. A. Bell, which, when first shown to me, I thought was 
a new species, but as it may possibly be the immature form of 7. elegans 1 hesitate to 
give it a new name.
