This is a local species, but abundant where it occurs. 
It has an extensive distribution throughout Great Britain, 
as far north as Skye, and also in all four provinces of 
Ireland. 
Its chief distinction from /7. Azsfrda is its umbilicus 
which is very small, while that of the last species is broad 
and deep; besides which the form of AZ. gvanulata is 
more globular, the spire more raised, and the bristles 
thicker. The usual colour of //. Azspida is much the 
darker. 
It has the habit of falling from its station on the nettles 
or other plants at the least touch or shake. It is very 
difficult to clean perfectly.
