PYRAMIDULA ROTUNDATA. 191 
Var. rufula Moquin-l'andon, Hist. Moll., 1855, ii., p. 107. 
Helix rotundata var. 6 Draparnaud, Tabl., 1801, p. 93. 
Helix rotundata var. 3 unicolor Gassies, Moll. Agen, 1849, p. 106. 
Heltx rotundata var. obscurata Dumont and Mortillet, Moll. Sav., 1857, p. 42. 
Helix rotundata var. subrufula Pascal. 
SHELL of a brown or fawn colour, without or with scarcely visible markings. 
The var. rufula s.s. is of a fawn colour, without markings. 
The sub-var. obseurata is brown, with few and faint fawn fleckings. 
The sub-var. subrufula is dark fuscous, with scarcely perceptible flammules. 
This variety is the one most likely to be confused with P. ruderata; and it is 
hoped that a careful study of specimens in the field and in collections will result in 
the addition of P. ruderata to our fauna.

VARIATION IN SIZE OF SHELL. 
Var. major Locard, Etud. Var. Moll., 1880, vol. i., p. 73. 
SHELL larger, usually somewhat depressed, and paler than the type. Diam. 
8-9 mill. 
Notts.—In a damp scullery, Highfield House, Beeston near Nottingham (E. J. 
Lowe, Conch. Notts., 1853).

Var. minor Jeffreys, Brit. Conch., 1862, p. 219. 
SHELL smaller. Diam. 5 mill. ; alt. 2 mill. 
According to Jeffreys, this is probably an alpine form. He remarks that he has 
observed it not only in the Jura and the Alps, but also in the Shetland Isles and 
Guernsey, and considers its presence in our Upper Tertiaries as an evidence of 
its northern origin.
