22 SUPPLEMENT TO THE CRAG MOLLUSCA. 



Trophon VENTRicosrs ? Gray. Supplement, Tab. Ill, 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. 



Trophon Turtoni, Bean. Crag Moll., Appendix, p. 312, Tab. XXXI, fig. 2. Supple- 

 ment, Tab. I, fig. 11, a, b. 



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 eleyans, 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 Eelixstow. Fig. 6, a, b, Tab. II, 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 T. elegans I hesitate to 

 give it a new name.
