to be referred to the Chalk, but a more systematic examination 

 and description of the Chalk Foraminifera to be found in these 

 sands, is reserved for a future and special paper of their own in 

 this series. 



Before beginning the Catalogue we may perhaps be allowed 

 to call attention to certain idiosyncrasies of these sands. Fore- 

 most among these, of course, is the fact that highly varying forms 

 of the same species are to be found together at all points of the shore. 

 Next, that besides the new genus Cycloloculina in its two species 

 dnnulata and polygyra, there are to be found in these sands a 

 notable number of species among the recent forms that are entirely 

 new to the student of the Foraminifera, whilst some forms are 

 recorded as fossils that have never before been found excepting in 

 recent gatherings, and, we may probably say, vice versa. Lastly, 

 the shore-sands furnish specimens of some few species that one 

 would never expect to find in a littoral gathering at all ; forms 

 having been encountered whose hitherto recognised habitat has 

 been the profundities of great oceans, whilst others are of species 

 hitherto regarded as brackish water, or estuarine, species. 



The shore-sands of the British Islands have not hitherto 

 received that systematic attention from Ehizopodists to which 

 their interest entitles them, but in connection with the deposits 

 now under consideration we may mention that a short list of the 

 Foraminifera of this district was contributed by Mr. F. W. 

 Millett, F.E.M.S., to Mr. Alfred Bell's paper " Notes on a Post- 

 Tertiary Deposit in Sussex " in the Yorkshire Philosophical 

 Society's Pieport, 1892. This list was subsequently supplemented 

 by a privately circulated note issued by Mr. Millett, entitled " The 

 Foraminifera of a Post-Tertiary Deposit in Sussex," from which 

 we learn that the material examined consisted of about three 

 ounces of coarse sand, and at the end of which the author 

 remarks : " It is evident that the deposit contains Foraminifera 

 derived from the Eocene, and possibly from the Cretaceous, forma- 

 tions, mixed with a large number of recent specimens, the 

 remainder being composed of Tertiary forms, to which, under 

 the circumstances, it would be difficult to assign the exact 

 horizon. Some of the species are represented by specimens both 

 recent and fossil. This note, necessary to explain the incon- 

 gruous concourse of species, was omitted from Mr. Bell's com- 

 munication to the Society." 



The appended list contained fifty-six species, of which in the 

 subjoined catalogue will be found all but four, which will, no 

 doubt, come to light at an early date. 



It is the circumstances recorded in this brief introduction 

 which have led, and encouraged, us to take the district very 

 seriously, and to devote to the examination of its shore-sands an 

 amount of close attention which, we trust, Pihizopodists will agree 

 with us, has not been unworthily or unprofitably applied.
