a 
72 HYALINIA NITIDULA. 
In Hampshire, HM. nitidula is recorded by Mr. J. 'T. Kemp as common 
in tufa at Southampton Dock, and near the waterworks in the Itchen 
Valley, and is also rarely found at Mottisfont in the lest Valley. 
In East Kent it has been found by the Rev. R. Ashington Bullen in a 
deposit overlying the rubble-drift at Barton Court, Buckland, near Dover, 
and by Mr. J. W. Jackson in the brick-earth at Rochester. In West 
Kent, Mr. A. Santer Kennard discovered specimens at the base of a rain- 
wash deposit, from two to six feet thick, at Darenth, and has also been 
found in the sandy deposits exposed in excavating the reservoir for sewer 
outfall at Crossness. 
In Surrey it was found by the Rev. R. A. Bullen at a depth of from 
eighteen inches to three feet in a Neolithic deposit at Colley Chalk-pit, 
near Reigate, and in alluvial loamy-clay on ''hames bank at Kew by 
Mr. T. Belt. 
In South Essex it has been found by Mr. F. C. J. Spurrell at Albert 
Docks (B. B. Woodward, Proc. Geol. Ass., 1890, p. 344); and in shelly- 
marl at East London Waterworks, Walthamstow, in which locality the 
authors describe these fossils as separable into a large form, attaiming a 
diameter of 11 mill., and a smaller one of only 6°5 mill., “known on the 
continent under the name of V. xétens Mich.” (Kennard and Woodward, 
Essex Nat., 1902, p. 18); peat-beds at ‘Tilbury Docks, and post-glacial 
beds at Witham, Dr. 8S. P. Woodward (Kennard and Woodward, “Essex 
Nat., 1897, pp. 92 and 108). In North Essex, Mr. Miller Christy found 
it common in black-earth, peat, and shell-marl at Chignal St. James ; 
as well as in an alluvial deposit, at Duke’s Farm, Roxwell; Mr. French 
has also detected it in ‘the alluvial shell-marl at Felstead; and the Rev. 
A. J. Law in a drain section in “The Marsh,” by Shalford Vicarage. 
In Middlesex, in the old river bed, a mile west of Staines, on tow-path 
to Old Windsor, A. Loydell (Kennard and Woodward, Proc. Geol. Ass., 
1906, p. 253); sandy deposit, Clapton, J. E. Greenhill ; and from section, 
Charing Cross Railway, Blackfriars, by C. J. A. Meyer (B. B. Woodward, 
op. cit., pp. 342 and 352). 
In East Gloucester it was found among the old soil of an Holocene gravel 
pit, Cleeve Hill, near Cheltenham (Hinton and Kennard, Proc. Cottesw. 
Nat. Field Club, 1904, p. 65). 
In Scotland, Mr. T. Scott has found it, though not commonly, in the 
deposits close by Ehe Railway Station in Fifeshire. 
In Ireland, the Rev. A. H. Delap found examples in a marl deposit at 
Marlfield, near Clonmel in South ‘Tipperary ; and Mr. R. Standen records 
it from the earthy deposit at Dog’s Bay, Galway West. 
In France, M. Fagot reports that in the Haute Garonne Zonites nitens 
is very common in the deposit at Quartier de Caraman near Avignon, and 
Z. subnitens in the grey argillaceous beds at Hers. 
In Belgium, /7. nitidula is, according to M. Grégoire, very common in 
the 'Tourbe at Uccle lez-Bruxelles. 
Variation.—The variation in the present species is not great, consist- 
ing chiefly in the greater or lesser dilatation of the last whorl and the 
occasional variation from the dull horn-coloured shell to a crystalline 
white or pearly aspect. Prof. Cockerell many years ago described a 
specimen from West Northdown, Isle of Thanet, which he referred to this 
species, that showed a broad, brown, spiral band, below the periphery, 
occupying the position of band 5 in the pentateeniate formula, and which 
he afterwards termed var. fasciata.
