E. VANDEN BROECK ON SOME PLEISTOCENE FORAMINIFERA. 197 



the following ten, which I collected from the Bueeto beds at nearly 

 2000 feet above the sea-level. 



Cardium ciliare, Lam. Trochus crenulatus, Brocc. 



echinatum, L. exasperatus, Penn. 



edule, L. Cerithium reticulatum, Mont. 



Nassa Ascanias, Brug. Phasianella pulla, L. 



Rissoa ciinex, L. Dentalium entalis, L. 



All these species are now living in the sea of the neighbourhood, 

 though Nassa prismaiica and Murex vaginatus are rare ; and the 

 size seems to vary but little from that of recent specimens. 



As the recent character of the shells which lived anterior to such 

 great changes of configuration as have occurred in the neighbour- 

 hood is a fact of the highest importance, I thought that perhaps the 

 Foraminifera might throw further light on the age of the deposit, 

 and sent to my friend M. Vanden Broeck, of Brussels, some of the 

 clays I brought from Ischia*. These, he found, did not contain any 

 Foraminifera ; but subsequently finding a few in the clay matrix of 

 one of the fossils, I sent a pill-box full to Brussels, and received 

 some most interesting remarks in a letter from M. Vanden Broeck, 

 and with his permission communicate the following translation. 



Note on the Foramininifera. By E. Vanden Broeck. 



According to promise, I now send a list of the Foraminifera which 

 I found in the last sample of marl you asked me examine. There 

 were : — 



Dentalina communis, If Orb. Cassidulina laevigata, 1)' Orb. 



var. consobrina, D' Orb. Globigerina bulloides, JD' Orb. 



guttifera, I 'Orb. Discorbina globularis, If Orb. 



Lagena lsevis, Mont. rosacea, If Orb. 



marginata, Mont. Planorbulina mediterranensis, If Orb. 



var. lucida, Will. Haidingeri, If Orb. 



squamosa, Mont. Trunoatulina lobulata, W. $• J. 



Bulimina pupoides, UOrb. Rotalia Beccarii, Linne. 



aculeata, If Orb. . nitida, Will. 



Virguiina Schreibersii, Czjzek. Pulvinulina auricula, F. $ M. 



Bolirina punctata, D'Orb. Nonionina depressula, W. $ J. 



plicata, V Orb. scapba, F. $ M. 



Textularia pygmgea, If Orb. Polystomella striato-punctata, F. Sf M. 



Verneuilina tricarinata, If Orb. crispa, Linne. 



spinulosa, Reuss. 



This small fauna has, without doubt, a more recent facies than 

 that of the Subapennine deposits properly so called. 



All the species from the marl are found now living either in the 



* Costa has, in his ' Paleontologia del Regno di Napoli,' described a large 

 number of Foraminifera from Casamicciola, which is of the same age as the 

 Monte-Buceto clays ; but he unfortunately gave nearly every species a new name, 

 and entirely neglected the size ; so that his lists of the fauna are not so useful as 

 they otherwise would be. They, however, show the very recent nature of the 

 deposit.
