Of Philippics valuable ' Enumeratio Molluscorum Sicilise/ 

 the first volume of which was published at Berlin in 1836, 

 the second volume appeared in 1844 with the distinct title, 

 ' Fauna Molluscorum viventium et in tellure tertiaria 

 fossilium Regni utriusque Sicilise/ Halis Saxonum, sump- 

 tibus Eduardi Anton. Particular attention has been devoted 

 in this volume to the complete enumeration of the species 

 of Mollusca occurring in those countries, to the distinguishing 

 by certain characters, of doubtful and new species, and to 

 the correction of the synonymy. According to the author's 

 statement in the Introduction, there were enumerated in 

 the first volume 640 living, and 367 fossil species from the 

 Island of Sicily ; in the second volume the researches were 

 extended to the entire kingdom of Naples, and in conse- 

 quence of this, the number of the described living species, 

 has been raised to 814, and that of the fossil to 589 ; and 

 258 species have been here, for the first time, figured on 16 

 lithographic plates (tab. xiii to xxviii).

 species are added, the names of which will be given below.
