of the Foraminifera, his Niffelheim may certainly lie found in the 

 material which, for the past year, has occupied my leisure 

 moments, and the appellate jurisdiction of my friend and col- 

 laborator, Arthur Earland. I refer to the material which may lie 

 scraped at any time, between tide-marks, from the surface of t In- 

 shore sand of Selsey Bill, which extends from the point of the 

 Bill north-westwards, through Bracklesham Bay, to the brackish 

 waters of Chichester Harbour, opposite Hayling Island and the 

 Isle of Wight. When first I suggested devoting my attention to 

 this material to Mr. F. W. Millett, he returned me a highly 

 characteristic answer, and one which would have seriously damped 

 the ardour of a beginner. He said : " The specimens of Fora- 

 minifera are interesting, but I cannot quite see how you are to 

 make a useful monograph out of this jumble of fossils washed 

 out of uncertain beds from unknown localities." 



In the beLrinnins: I found Mr. Earland at one with him, but as 

 I continued doggedly upon the quest, Mr. Earland came round to 

 my view that this is, perhaps, the most remarkable and suggestive 

 foraminiferous deposit to be found in the British Islands. The 

 completed study of the Foraminifera of the locality, we hope to 

 lay before the Society at a future date, but it has seemed good to 

 us to introduce the subject, with a paper upon a most interesting 

 form continually recurrent in the material, which, at first, we were 

 disposed to regard as a new species of Planorbulina, but which we 

 have gradually been forced to recognise as a new genus, for which 

 we propose the generic name of Cycloloculina, and which we have 

 the honour to lay before you in two species, named respectively 

 Cycloloculina annvlata and C. jpolygyra. 



It will not be impertinent to the consideration of the genus to 

 devote a few moments to the history of its discovery. Selsey Bill 

 is the peninsula resembling, as it were, an " uvula " dependent 

 from the extreme south-west of Sussex, a few miles only from the 

 borders of Hampshire ; and there is probably no locality upon the 

 coast lines of Great Britain which has attracted in a greater degree 

 the earnest attention of geologists. It may be said at once that the 

 whole of the district under consideration, forms part of the most 

 noteworthy of the raised beaches which occupied the attention of 

 Professor Prestwich, and were so learnedly and lucidly described 

 and discussed by him in the ' Quarterly Journal ' of the Geological 

 Society in 1892.* For the purpose of this paper, the geological 

 interest of this shore commences at Bracklesham Farm, which is 

 situate just beyond the western boundary of the Geological Survey's 

 Map, Sheet 332, and opposite which lies the great bank of Eocene 

 fossils which is exposed at low tide, and is composed of agglome- 



* This raised beach extends from Brighton on the east, to Portsmouth on the 

 west, and includes the whole district south of a line drawn from Portslade through 

 Arundel to Havant (Postscript, No. 11).
