SAARET FOSSILS. 



with a Touraine species, has lately been brought 

 from New Guinea by Mr. Hinds. On the whole, 

 we are inclined to regard this Lycian tertiary 

 as of miocene age, synchronic with the for- 

 mations of Bourdeaux and of Touraine, and 

 with the miocene tertiaries of Italy. 



The following species of fossil testacea were 

 collected by us in the Saaret beds : 



Dentalium, very near, if not identical with, the living Denta- 

 lium dentaUs. 



Dentalium, very near, if not identical with, Dentalium 

 entalis. 

 Bulla. 



Natica, identical with the Bourdeaux fossil called Natica 

 canrena by Basterot. 



Natica olla, of Marcel de Serres, a living Mediterranean 

 species. 



Natica, a third species. 



Turritella, very near Turritella pvoto of Basterot. 

 Turritella spirata of Brocchi. 

 Conus deperditus of Brugiere. 

 Oliva. 



Ancillaria obsoleta of Brocchi. 



Voluta, apparently a variety of Voluta rarispina, a Bour- 

 deaux fossil, but differs in having four plaits on columella. 

 Mitra, very near M. plicatilis of Brocchi. 

 Cancellaria calcarata, Brocchi. 



Columbella — Fusus politus of Bronn, or Nassa columbel- 

 loides of Brocchi. Identical with a Touraine fossil. 

 Terebra plicaria, Lam.
