ISTORY. — Theba cantiana would 
appear to have been first observed by 
Dr. Martin Lister and cited by him in 
1678 as a large variety of Helix rufescens, 
or as a distinct species found in Kent. In 
18OL Draparnaud detected the species in 
the south of France, and described it under 
the name of AHe/ix carthusiuna, mistaking 
it for Miiller’s species of the same name ; 
afterwards in 1805 it was figured and fully 
described in his ‘‘ Histoire.” 
In 1803 our own countryman Colonel 
Montagu again brought the species forward, 
figuring and deseribing it under the name 
of Helia cantiana, by which appellation it 
is now generally known. 
With the present species I associate the 
late Archidiaconus Adolf Sehmidt, of 
4 Aschersleben, the venerable conchologist 
A we ae Le and malacological anatomist, who was the 
e ~ first to describe and carefully figure the 
organization of “ Helix galloprovincialis,” Dupuy, the south European form 
of Theba cantiana. He was also in his time the universally acknowledged 
authority upon the ditheult genus Clausilia, upon which group he wrote 
several valuable monographs. 
‘he portrait, for which I am indebted to Herr Paul Hesse, of Venice, 
represents the distinguished scientist in the eighty-fifth year of his age. 
Dr. Kobelt was decidedly of ee that H. galloprovincialis of Dupuy 
and H. cantiana of Montagu were two well marked species, but the figure 
of the internal organs given by A Schmidt of a South European example 
quite coincides with that of British specimens of the typical form. 
Helix iadolw Bourguignat and the Corsican Helix ousterea, monerebia, 
and gaudefroyi of Mabille have all been regarded as synonyms by authors 
of repute, while Dr. Kobelt has remarked that /Z. /requens Mouss., H. 
ancone Issel, and H. dirphica Blane are scarcely to be distinguished from
