256 HELIX ASPERSA. 
, ENGLAND AND WALES. 
Cornwall W.—Truro, 1885 ! J. H. James. 
Devon N.—Sub-var. maxima Parfitt abounds on the sandhills at Braunton 
Burrows near Bideford. 
Somerset N.—Var. major, specimens in the British Museum from Blagdon and 
Weston-super-Mare, and Mr. Swanton has found in hedges about Bratton St. Maur 
‘shells quite as large as H. pomatia,” and approaching var. nigrescens in coloring. 
Middlesex—A specimen of the var. major from the neighbourhood of London, 
kindly given me by Mr. Howard Vaughan, is 40 mill. in diameter ! 
Glamorgan—Llandaff, E. Collier. 
York N.E.—Very large specimens are found at Pickering, according to the late 
Rev. W. C. Hey. 
CONTINENTAL DISTRIBUTION. 
France—-The var. major is reported by Pascal as common about Paris ; and 
Dupuy records specimens from Preste, Pyrenees Orientales, ‘‘as large as the largest 
Algerian shells” ; while Nevill reports gigantic tumid forms from an altitude of 
3,000 to 4,000 feet on the mountains near Menton, Alpes Maritimes. 
Spain—Dupuy has recorded that he possessed shells from South Spain larger 
than the largest H. pomatia. Valencia! R. D. Darbishire. 
Balkan Peninsula—Var. major, a Dalmatian specimen obtained from Verkruzen 
measures 40 mill. in diameter. 
Sicily—Caleara cites a var. “magna” as found in Sicily. 
Greece—Mrs. Fitzgerald has reported that the largest shells in her collection 
were collected in Greece. 
Palestine—Canon Tristram records specimens ‘‘quite equalling those of Algeria” 
from gardens about Tyre, Sidon, Beyrout, Jaffa, and other places on the coast. 
Algeria —Var. major, specimens of this variety in the British Museum from 
Constantine. M. Lallemant also records the variety from Kabylia, remarking that 
they are larger, darker, and more shagreened than the specimens from Algiers, 
which vary little in colour or form. Algerian specimens procured from Verkruzen 
constitute the types of sub-var. maxima Taylor. 
Tunis—Magnificent shells are recorded by Letourneaux and Boureuignat from 
the Valley of Medjerda. 
Var. minor Picard, Moll. Somme, 1840, p. 180. 
Helix (Pomatia) aspersa var. nana Nevill, Proc. Zool. Soc., 1880, p. 113. 
SHELL smaller than the type. 
This variety was first figured by Ferussac, but 
several authors have independently defined a var. 
minor; that of Picard is deseribed as not exceeding 
20 mill. in diameter or height; Dr. Baudon gives 
25 mill. altitude and about 23 mill. diam.; Marchesa 
Paulueci 26 mill. altitude and 25-28 mill. diameter ; 
Jourgnignat says altitude 25-30 mill. and diameter Fic, 324.— Helix aspersa var. 
25 mill.; Westerlund, 25 mill. diameter and 27 mill. 7” Picard ( Sen) 
altitude ; and Nevill a diameter of 28 mill. and an altitude of 22 mill. 
The sub-var. nana is described as 25 mill. in diameter and 21$ mill. high. 
M. Picard, who first described the var. minor, hazarded the conjecture that they 
might be really immature shells which had prematurely formed and completed the lip. 
Baudon remarks that his var. minor resembles the var. maritima of Bouchard- 
Chantereaux from Boulogne-sur-Mer. 
ENGLAND AND WALES. 
Channel Isles—In Guernsey it is rather common and of typical texture in the 
north of the island; one specimen found at Petit Pot Bay is only 21 mill. in

1885 near Arnold’s Pond, North Guernsey, and at Ieart in the south of the island. 
Messrs. Tomlin and Marquand also report it from Herm ! and cite one from Clanque, 
Alderney, only 19 mill. in diameter.
