Adanson does not mention any naked mollusca, and only two 

 species of land and fresh-water shells. 



Of 58 marine Bivalves of Senegal there are in South Italy 10 or 17 percent. 

 131 conchiferous Gasteropoda - - - 18 or 14 - 



Here also, therefore, it is observable that a greater analogy 

 holds between the Bivalves of the two regions than between the 

 Gasteropoda. 



The fauna of Senegal is much more different than that of the 

 Canary Islands from the fauna of the Mediterranean. This last 

 has 68 per cent, of its bivalves common to both, and the Senegal 

 only 17, while the Canaries have 47 per cent, of the gasteropoda, 

 and Senegal only 14 per cent, common. In the latter region, 

 we find several species of Voluta, Terebra, Strombus, Nerita (in 

 its limited sense) ; and still more numerous are the examples of 

 Conus, Cyprcea, Marginella, Ostrea, &c, and it is especially re- 

 markable that one solitary and very small species of Pecten is 

 enumerated by Esson, but is yet undescribed. 



5. Comparison of the Fauna of the Red Sea with that of South 



Italy. 

 In the year 1834 I arranged and described, at the request of 

 Professor Ehrenberg, the shells collected in the Red Sea and its 

 vicinity by Messrs. Von Hemprich and Ehrenberg, but the publi- 

 cation of the results has been, up to this time, delayed. The 

 information thus derived has served as the groundwork of the 

 following comparative tables. The Red Sea has in common with 

 South Italy : —
