I. Remarks on the Molluscous Animals of South Italy, 

 in reference to the Geographical Extension of the Mollusca, 

 and to the Mollusca of the Tertiary Period. By Dr. A. Phi- 

 lippi. 



[From the Archiv fur Naturgeschichte, vol. x.] 



During my last two years' residence in Naples and Sicily, in 

 the years 1838 and 1839, I have had an opportunity greatly to 

 extend my earlier researches on the mollusca of Sicily, and the 

 fossils of that tribe of animals whose remains are there so ex- 

 ceedingly abundant. Amongst other things, I have been enabled 

 to bring within the sphere of my observation the group of tertiary 

 fossils of South Calabria, which district I have traversed in 

 several directions, from Cape delle Armi to the ancient Crotona, 

 and have now published a second volume of my " Enumeratio 

 Molluscorum Sicilian," in which I enumerate 814 species of living 

 mollusca, and 589 fossil ; whilst in the first only 540 living, and 

 367 fossil species appear ; so that the additional volume contains 

 274 living and 222 fossil species, which are wanting in the first. 

 In this new work 258 species are figured in 16 plates. Among 

 the 274 newly described species, there are, however, .about 95 

 which I have not myself seen, or of which I have some doubt 

 whether they really are indigenous in South Italy ; and many of 

 these may require to be struck out of the list, especially several 

 of the numerous Helices, described as Sicilian by Messrs. Aradas, 

 Calcara, Testa, and other naturalists. Since, however, the descrip- 

 tions of these new species are often unsatisfactory, I have avoided 

 offering an opinion concerning them, and have contented myself 

 with giving an account of them in the words of the author. 

 Owing to this, I have felt myself obliged to relinquish the com- 

 parison of the land and fresh-water mollusca of Sicily with those 

 of other countries, but I have done so the rather, and confined myself 

 to the marine mollusca, because these latter alone have reference 

 to the fossils of the tertiary period. Unfortunately we possess, 

 from very few districts, even tolerably complete lists of the mol- 

 lusca, and can rarely rely on the general works, such as those of
