Zonites cellaria, Miiller ; 3. Helix malleata, Ferussac ; 4. H. adansoni,Wehh & Berthelot; 5. H. lac tea, Miiller; 6. H. apicina, Lamarck; 7. H. circumsessa, Shuttleworth ; 8. H. lenticula, Ferussac ; 9. H.fortunata, Shuttle-worth ; 10. H. pavida, Mousson ; 11. H. phalerata, Webb & Berthelot; 12. H. lancerottensis, Webb & Berthelot; 13. H. lineata, Olivi; 14. Bulimus tarnerianus (junior?), Grasset. Of the above species Nos. 2, 5, 6, 8, 12, 13 are not restricted to the Canaries, but range further north, either to North Africa or Europe. For a full account of these species and their distribution, reference should be made to the ' Testacea Atlantica ' of Wollaston. Besides the species already enumerated, two small examples of Limax canariensis of d'Orbigny were collected at this locality, agreeing in every particular with d'Orbigny's description excepting size, from which it is concluded that they are but half-grown, being about an inch in length in contraction. CAPE DE VERD ISLANDS. Only two species of Helicidae were collected at St. Vincent, namely Helix advena, Webb aud Berthelot, and //. bollei of Albers. ASCENSION ISLAND. The only land-shell met with, Helix (Fruticicola) similaris of Ferussac, is almost cosmopolitan, and has previously been recorded from this locality. The unhanded variety appears to be more common than that with a peripherial brown zone, judging from the series of 240 specimens at hand. SOUTH AFRICA. The following species were obtained in this district: Limaxgagates, Draparnaud (1=L. capensis, Krauss), and Helix aspersa, Miiller, from the Cape of Good Hope ; also a young specimen of the latter from Sea Point near Cape Town, and Helix qfra, Pfeiffer, from Simons Bay. It will thus be seen that the first two of these species are well-known British and European forms, and doubtlessly have been introduced. The single specimen of H. afra differs from that described by Pfeiffer in having the perforation entirely closed by the expanded columellar callus. The lip also is quite thin, without any internal thickening, and even in the type itself this is very slight and some distance from the extreme margin, which, being the last-formed part of the shell, has not received so much internal callus. BERMUDA. All the terrestrial mollu<ks obtained at this locality are well-known forms, but one, the common European Limax gagates, has not, I |
