aspera and crenata are really nothing but different names for the 

 same shell, as Weinkauff asserts, it is quite certain that the 

 Patella wliich D'Orbigny has described under the name of P. 

 Lowei, is a separate species. 



" 30. Oyprcea spurca, Linn." 



Thus given by D'Orbigny. It is also Madeiran. 



" 31. Cerithium vulgatwn. See above." 



"32. Cyprcea lurida" 



" Thus given by D'Orbigny. Also Madeiran. 



" 33. 1 



34. lo."

" 41. Conus grandis, Sowerby, Gen. Capital. More." 

 This is published by D'Orbigny under the name of O.prome-

 it is attributed to " d'Orb." 



It is (^de J. Gwyn Jeffreys in litt.) the P. rustica, L. & Dill., 

 = P. lusitanica, Gmel., = P. punctata, Lam., = P. nigropunctata, 

 lieeve.
