HYALINIA CRYSTALLINA. 111 
Geological Distribution.—Z. crystallina has been detected in the 
fossil state in the Lower Pliocene deposits of France, but in this country 
it has not been authentically reported from beneath Pleistocene strata, 
although the late Mr. Searles V. Wood in his great work on the Crag 
Mollusca, comments on the finding of HZ. crystallina in association with 
Cyclostoma elegans in the upper layers of the Coralline Crag, but he 
regards their presence there as probably adventitious and that the 
material in which they were found was in all likelihood a disturbed 
deposit of a more recent period. 
Lower PxiroceNE.—Sandberger records this species as found in the 
Lower Pliocene strata of Hauterive in the department of the Dréme and 
from those of Celleneuve in the Herault. 
PLEIsTocENE.—H. crystallina is reported as having been found in these 
deposits at several places all in the south-east of England. 
In Sussex W., it has been found by Mr. J. P. Johnson in the buried 
river-bed deposit on the foreshore at West Wittering. 
In Kent W., recorded from the famous Ightham fissure, near Wrothain, 
by Mr. W. J. L. Abbott ; andin East Kent by Prof. Morris from the fresh- 
water deposits at Maidstone. 
In Essex 8., recorded from the Paleolithic deposit at Uphall brickyard, 
Ilford, by Mr. J. P. Johnson, and from the freshwater marls of Clacton 
and Copford, in North Essex, by Prof. Morris. 
In Cambridge, found in the gravels of Barnwell Abbey and Grantchester 
by Rev. E. 8. Dewick and Mrs. McKenny Hughes. 
In Germany, Sandberger records Hyalinia crystallina as not rare in the 
Lower Pleistocene sands of Mosbach, Baden ; as not common in the Mid 
Pleistocene beds of Cannstadt, Thuringia; the loess of Oos and Grotzingen 
in Baden ; and Robschutz, Zscheilitz, and Niederjahna in Saxony. Herr 
Clessin has found it in the tufa beds of Regensburg, Bavaria ; and Sand- 
berger records H. swhterranea in the valley loess of Heidelberg. 
In France, Sandberger records it as scarce in the Mid Pleistocene beds of 
Hauterive in the Dréme, and Celleneuve in the Herault ; Locard from those 
of Celle, Seine et Marne, and from the bone breccia of Bastia in Corsiea. 
In Austro-Hungary, Clessin quotes it from the loess of Heiligenstadt 
near Vienna. 
In Switzerland, it is recorded from the loess of St. Gall by Sandberger. 
In Madeira, one example thought to be from the compact layer of fine 
sand at the base of the Upper Pleistocene fossiliferous beds at Canical 
(R. B. Watson, Journ. de Conch., 1876, p. 222). 
Hotocene.—In Somerset S., it is reported from a rainwash of probably 
no great age at Aleombe, near Minehead. 
In Wilts. N., also from a similar deposit at Little Bedwyn, and 
In Dorset from the tufaceous beds at Blashenwell, near Corfe Castle, 
all by Mr. A. Santer Kennard. 
In Hants. S., common in tufa at Netley Shoal, at Mottisfont in the Test 
Valley, and rare in tufa at Southampton Dock (J. ‘I’. Kemp, Proe. Hants. 
Club, 1889). 
In the Isle of Wight, it is recorded from a tufaceous deposit south-west 
of Widdick Chine, Totlands Bay (Kennard & Warren, Geol. Mag., 1904).
