64 HYALINIA ALLIARIA. 
Var. euprea Westl., Faun. Paliaret’ Reg. Binnenconch., 1886, p. 43. 
SHELL larger and stronger, not so glossy, ruddy-brown, sometimes whitish 
beneath ; aperture more descending. 
This is given by Westerlund as subsidiary to his H. cantabrica. 
Spain—Bilbao in the Basque province (Westerlund, l.c.). 
Var. suballiaria Bourguignat in Pechaud’s Exc. Malac., 1883, p. 21. 
SHELL more openly umbilicated than the type, and the suture finely wrinkled, 
last whorl strongly developed, and the mouth more obliquely elongated. 
Algiers—(Bourguignat, l.c.). 
Var. aquitanica Charpentier. 
SHELL similar in size and convexity to H. glabra, but with a wider umbilicus. 
France—Department of the Landes (Von Martens, Die Heliceen, 1860, p. 69). 
Italy—Tuscany (Westerlund, Faun. Eur. Moll. Extram., 1877, p. 20).

Geographical Distribution.—/. alliaria is another species con- 
cerning which a great amount of misapprehension has existed, and this 
unfortunately has led to an amount of uncertainty as to the reliability or 
otherwise of many of the records, especially when the remarks which 
sometimes accompany them are studied. 
Judging by the records, this species has a wide European distribution, 
and this is probably really the case, though a thorough knowledge of -its 
distribution is probably obscured, as it has far too often been regarded as 
an immature stage of some of the larger species, but it is hoped that the 
ample details of its structure now furnished will lead to its inhabited 
area becoming more accurately known. 
In the British Isles it is a well distributed species from the Shetland to 
the Channel Isles, and there are few comital areas from which specimens 
have not been seen and verified,
