They may most easily be recognized by their very soft, sooty fur. 
I have endeavoured, as far as possible, in the following lists, to assign 
each name to a group, but, in some instances, this has been found impossible, 
and in others there has been only a very scanty description to go upon. A 
group has not always been called after the name of the oldest species it contains, 
but rather after a species which is fully described and can be easily identified.
