PEEFACE. 



The Catalogue of the Cephalopodous Mollusca by Dr. A. H. 

 Foord, commenced in 1888 (two parts of which are 

 issued, the third part being now in the press), together 

 with the Systematic List of British Oligocene and Eocene 

 Mollusca by Mr. E,. Bullen Newton, in 1891, are the 

 only volumes already published on the fossil Mollusca in 

 this Department. 



The present work by Mr. Gr. F. Harris, on Tertiary 

 Mollusca, commences a new Catalogue ; the first part 

 being devoted to descriptions and figures of the shells of 

 Australasia (exclusive of the Cephalopoda), to be followed 

 by other geographical series in the collection, of equal 

 interest. 



Although thirteen volumes on Fossil Yertebrata, eight 

 volumes on Fossil Invertebrata, and three upon Fossil 

 Plants, have already been published by the Trustees, the 

 larger part of the Mollusca and Bryozoa, and the whole 

 of the Brachiopoda, Annelida, Arthropoda, Echinoderma, 

 and Ccelentera, remain to be recorded, as well as the 

 greater portion of the fossil plants, so that probably 

 not less than thirty volumes will be needed to contain. 

 even a brief account of these very varied and extensive 

 collections.
