ISTORY.—J/elicigona arbustorum (arbus- 
torum, living in copses), though binomially 
distinguished by Linné, was first noticed 
and described by Dr. Martin Lister, the 
real pioneer of the science of Conchology. 
On account of the great variability of this 
species, numerous names have been be- 
stowed upon it by Mabille, Servain, and 
others, who elevated to specific rank a 
number of forms which are probably more 
correctly regarded as varietal only. 
& 
With this species I have associated my 
late valued friend and correspondent, Prof. 
Eduard von Martens, of Berlin, the most 
distinguished conchologist of his time, who 
selected this species for the present purpose 
as the first he collected, it being very 
abundant by his home at Stuttgart and 
Jrof Edu asd Von Martens a form in which he always retained a lively 
interest,
