Paris," unites the French fossil and the two English ones under one 

 name, although they are perfectly distinct ; probably he has not exa- 

 mined English specimens. We find the characters very constant, and 

 easily observed v^hen once pointed out. The analogous shells of Bor- 

 deaux are equally distinct. About the same size as R. riinosa, M. C, 

 from Barton. 

 Loc. Soomrow. 



Itostellaria rectirostris. (Lam. Hist. Nat. vol. vii. 192.) The elongat- 

 ed form induces us to refer this fossil to the recent it. rectirostris^ in 

 preference to any other species. 



Loc. Soomrow. 



Stromhus deperditus. Turbinate, tuberculated, and transversely 

 striated ; tubercles united by a slight carina gradually increasing in size ; 

 lip thickened, produced above into a short pointed lobe. Height 21 

 inches, diameter i inch 4 lines including the wing. 



Much like Siromhus Gallus^ Linn., and S. bituberculaius, Lam., but 

 the tubercles are of an equal size on the last whorl and not much larger 

 than on the spire. The aperture is not much dilated, so that the wing 

 is rather small. It appears to be a very common shell in the Runn, but 

 perhaps there are several species, as many of the specimens are so 

 firmly attached to the stone, and so much concealed, that the distin- 

 guishing marks cannot be traced. 



Loc. Soomrow. 



Stromhus jiodosus. Turbinate, elongated, tuberculated, transversely 

 and longitudinally striated ; tubercles equal, numerous, prominent, 

 obtuse. Height If inches. 



Distinguished by the rounded tubercles, of which there are about 12 

 to each whorl- and the elongated spire. 



Rare— we have seen but one specimen and that is very imperfect. 



Loc. Soomrow. 



Cassis {Ci/pr(scassis, Stutchbury,) sculpta. Ovate, transversely sul- 

 cated ; aperture narrow, the outer lip plaited, the inner smooth. Height 

 ]| inch, diameter 1 inch. 



Strongly resembling Cassis {Cuprcecassis, Stutchbury,) Testicidus 

 {Bucc. Testicidus, Linn.), but smoother, and with a narrower aperture. 



Loc. Soomrow. 



TvrUnelhts affinis. Subfusiform, swelled in the middle, ornamented 

 with many transverse ridges and a row of flatted tubercles near the 

 upper margin of each whorl ; beak produced transversely, ribbed ; 

 eoluraelia 5 -plaited. Height 4 inches, width 2 inches.
