T. Davidson — Tertiary Brachiopoda. 



363 



several excellent works, described the few species found by him 

 in Piedmont, but by far the larger number of these last, as well as 

 of those from Sicily, have been well described and illustrated by 

 Prof. Sequenza, of Messina. The species of the North of Italy and 

 of Tuscany have also been carefully studied by Sig. Meneghini, of 

 Pisa. Smaller contributions have likewise been made by Massa- 

 longo, Aradas, Calcara, Galvani, Biondi, Schauroth, Suess, and some 

 others, whose names and works will be referred to in the sequel. 



I propose, therefore, in this communication to review briefly the 

 whole subject, and to furnish the student with descriptions of the 

 new species, as well as some observations where necessary in con- 

 nection with those already known. I also propose to add a figure or 

 more of each species which, with few exceptions, I have drawn from 

 well-preserved specimens, for which I am indebted to several of the 

 gentlemen above named, in addition to the Cav. L. Eovasenda, of 

 Turin, and Sig. Eigacci, of Eome. I would also refer the student to 

 the works of the palaeontologists above named for descriptions and 

 lists of references, synonyms, etc., which, from want of space, cannot 

 be transcribed in this paper. The larger number of the Eocene 

 specimens figured by me belong to Sig. Meneghini, to the Museum 

 of Pisa, and to that of the Ecole Imperiale des Mines, of Paris.
