276 MR. E. A. SMITH ON THE MOLLUSCA [May 6, 



Canary Islands. 



Examples of the following species of Helicidse were collected at 

 Teneriffe : — 1. Vitrina lamarckii, Ferussac ; 2. Zonites cellaria, Mai- 

 ler ; 3. Helix malleata, Ferussac ; 4. H. adansoni, Webb & Berthelot ; 

 5. H. lac tea, Muller ; 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 canariensisot 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 and Berthelot, and H. 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 unbanded 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, Muller, 

 from the Cape of Good Hope ; also a young specimen of the latter 

 from Sea Point near Cape Town, and Helix afra, Ffeiffer, 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 intro- 

 duced. 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 mollusks obtained at this locality are well-known 

 forms, but one, the common European Limax gagates, lias uot, I
