ISTORY.— Helix pisana though recorded by 
Petiver, in 1711, from specimens collected 
near Pisa in Italy, was first binomially 
distinguished by O. F. Miiller, although 
Mr. Hanley found immature shells of this 
species in the Linnean collection, which he 
judged may have been intended to represent 
[. leucas, as there were no other shells in the 
cabinet that corresponded with the Linnean 
diagnosis, yet this evidence of identity is 
not sufficient to permit us to supersede the 
universally adopted Miillerian name. 
his species is the type of the group 
Huparypha, and is characterized by a 
narrowly perforate, subdepressed, calcareous 
shell, and the splitting-up of its spiral bands, 
while the aperture is internally thickened 
but not expanded, and although a Penta- 
je ie & teeniate species, has the banding so greatly 
= ee disintegrated that it is difficult to recognize 
the quinquefasciation. 
Helix pisuna was added to the British fauna by Pennant, sno described 
the shell as a native species in his British Zoology, published i in 1777. 
With this species it is a pleasure to associate the Marquis Monterosato, 
a life-long and distinguished student of the mollusca, and the author of 
many invaluable authoritative Ww orks, who has especially studied the 
present species and differentiated some of its more interesting variations.
