432 Correspondence — The Rev. R. A. Biillen. 



At Portland Bill, in the loam or loess between strata of angular 

 debris from the Middle Parbecks, I found an interesting collection of 

 land and fresh-water shells. Mr, Edgar A. Smith, of the British 

 Museum (Natural History), has kindly determined the species for 

 me. They are : — 



Succinea ohlonga (Drap.) 41 specimens. Fupa muscorum (Linn.) 56 specimens. 

 Limncea peregra (Linn.) 4 ,, Cyclostoma elegans ... 1 ,, 



Helix hispida (Linn.) ... 1 ,, Fisiclium, sp 1 ,, 



Helix pulchella 5 ,, 



These shells are entire, but very brittle. A great many broke to 

 pieces in the process of washing out, and reduced my spoils. The 

 Cyclostoma was dug out of a large block of fallen loam by my wife, 

 but in such a position as left no doubt of its genuineness. Fifteen 

 of the P. muscorum are immature specimens; two of them have 

 only two whorls. Professor Prestwich has hitherto only found the 

 operculum of Cyclostoma at the Battery, Folkstone, and H. hispida 

 and a. pulchella at the same place. Pisidium does not occur in his 

 lists of Rabble Drift Shells as given in the Raised Beach paper 

 (Quart. Journ. Geol. Soc. 1892, vol. xlviii.), and of the above list only 

 S. ohlonga, L. peregra, and P. muscorum are named from Portland 

 Bill. I also found four specimens of Littorina litorea in the Rubble

Section of the Rubble-Drift, Portland. 

 Drift, one at a height of 4^ feet above the raised beach, from 

 which they have probably been derived. A large piece of mammalian 

 bone also occurred at the bottom of the second seam of angular 

 Rubble Drift, at (a), and which is only slightly adherent to the tongue. 

 I give a rough sketch of the section.
