On Cycloloculina. 541 



Cycloloculina was found among the finer sittings looking very much 

 out of place, and probably washed by the current Irom the point of 

 the Bill. A feature of the finer sittings were robust sponge-spicules 

 and fragments of a gem-mineral not yet identified. 



3. " Clibs." Principally Nummulites, with a disconcerting mix- 

 ture of recent forms, evidently washed out of the Pholas borings. 



4. Alvcolina limestone. Large casts in yellowish silica of 

 various Miliolinm, and perhaps some large Polymorphince. 



5. Under the Mixon Rocks. The same casts as in No. 4, with 

 a large proportion of recent arenaceous forms {Verneuilina poly- 

 stropha and Ifaplophragmium canariense, with large recent Miliolince 

 (Massilina secans). 



6. Opposite Marine Hotel. Suspending judgment as to the 

 single test dredged in 5 fathoms (No. 2), Cycloloculina makes its 

 first appearance here, where it is fairly plentiful. 



7. Opposite " The Bungalows." Here Cycloloculina is an in- 

 creasingly recurrent shell. 



8. Selsey Beds. A brown clay, full of derived Eocene fossil 

 Foraminifera, but no Cycloloculina found in situ. 



9. Blue Band. No sign of Cycloloculina, but many Estuarine 

 forms, such as Nonionina, Trochammina, etc., all filled with iron 

 pyrites. This band is full of vegetable detritus and fragments of 

 pyrites. 



10. Bracklesham Beds. An Eocene clay, very rich in fossil 

 Foraminifera, but no sign of Cycloloculina at present. 



11. Above the Selsey Beds. Here Cycloloculina is more 

 plentiful than anywhere else, the specimens being, for the most part, 

 delicate and perfect. 



12. Opposite the Oyster Beds. Here Cycloloculina is a re- 

 current form, though generally somewhat battered. 



13. Opposite Medmerry Farm. Here Cycloloculina is about as 

 common as in No. 12, but more battered as a rule. 



14. Pleistocene mud deposit. In the first small lump of this 

 mud which we washed we found a perfect Cycloloculina annulata 

 and a perfect C. polygyra, but many hours' patient search since 

 then have failed to produce a further specimen of either. The 

 utmost care is taken to use clean sieves and new muslins, but until 

 more specimens are washed out we must suspend judgment as 

 to this sample. 



15. From the shore of Bracklesham Bay. In this we have 

 failed to find any trace of Cycloloculina. The gathering consists 

 almost entirely of Eocene fossils, shell-detritus, with Xummulites, 

 and a striking collection of large glauconite casts of Foraminifera, 

 but few tests, either recent or fossil. We have, however, found in 

 this sample several specimens of the rare Polyraorphina complanata 

 figured by d'Orbigny in his " Foraminiferes fossiles du Bassin 

 Tertiaire de Vienne " (Paris, 1846).
