ISTORY.— Verophila virgata was 
first noticed and named polynomi- 
ally by Dr. Martin Lister in 1692, while 
the first binomial designation was that 
bestowed by Da Costa, whose species is 
certainly not Helix pisana as stated by 
Moquin-'l'andon. 
It has been assumed that the present 
species may be the Helix zonaria of 
Linné, a view which was accepted by 
his eminent contemporaries Da Costa 
and Pennant. 
I have pleasure in associating with 
the present species Prof. Paul Pelseneer, 
D.Sce., ete., of Brussels, Belgium, one of 
the very foremost of our truly scientific 
conchologists and the author of many 
valuable treatises upon the structure, 
development, and phylogeny of many 
molluscan groups. 
There are eight undoubted specimens 
of XY. virgata preserved in the Linnean 
Collection now in the possession of the 
Linnean Society of London, but no 
data exists in regard to them, and Mr. Sylvanus Hanley, who published 
a very exhaustive and excellent analysis of the shell collection of Linné, 
was apparently unaware of their presence in the cabinet.
