HYGROMIA STRIOLATA. 13 
MONSTROSITIES. 
Monst. subsealare Williams, Midl. Nat., July 1890, p. 165. 
Helix rufescens monst. scalariforme Swanton, Journ. of Conch., April 1903. 
**Whorls partly disjointed.” 
Dr. Jeffreys mentions a scalariform distortion of this species, but gives no indi- 
cation of the locality. 
ENGLAND. 
Surrey —A peculiar dislocated shell found at Haslemere! by Mr. E. W. Swanton. 
Norfolk E.— A single specimen found by Mr. A. Maytield at Eaton near Norwich, 
is the type of the monst. subscalare. 
Westmorland and Lake Lancashire.—Eggerslack Wood, Grange-over-Sands, 
1903, J. Wilfrid Jackson. 
IRELAND. 
Queen’s Co.—Maryborough, a very fine example, Oct. 1910! R. A. Phillips. 
Monst. sinistrorsum 'T'aylor. 
SHELL reversed in its coiling. 
This species, though so abundant, was quite unknown in the sinistral state 
until discovered by the Rev. W. A. Shaw in 1905. It is very remarkable that the 
only other known specimen should have been found in the same county. 
ENGLAND. 
Northampton — A single almost full-grown shell amongst nettles at East 
Haddon, May 1905, Rev. W. A. Shaw. A full-grown and _ perfect, though dead 
shell, in a nettle-bed, about a mile from Peterborough Railway Station, Aug. 1909, 
W. Gynegell. : 
Geographical Distribution. —'This species is fairly well diffused 
throughout its range in the British Isles, and not nearly so partial in its 
distribution as believed by Dr. Jeffreys. 
Fic. 24.—Geographical Distribution of Hygromia striolata. 
Probable Range. - MB Recorded Distribution. 
In England and Wales it has been found and verified for every comital 
or vice-comital district except from Nottingham and Montgomery ; the 
apparent and totally unexpected absence of this species from Nottingham- 
shire and excessive rarity in Leicestershire are as yet quite inexplicable.
