~ CLASSIFICATION. 
It may be as well to give the classifications of the genus 
by the fo four first-mentioned authors, to show how pond <n 
Canine (or Eu-canine) are related to the rest. Y 
tabular form which is, I think, the clearest aie of sing eck 
out. Though I fear the agrees will not be clear without 
it, it would occupy too much space to detail the characteristics of 
the sections, but I give tater on the leading athe of the aggre 
gate species which I have adopted and the ns by which they 
can be distinguished from the British species “of other sections. 
The subjoined tables only give the aggregate species corresponding 
to those in the er edition of ao eres Cat tot ie I have Soe 
given the minor species beca o two auth lassify th 
quite alike—in fact, most of aia ‘bake the plants ‘is have feeb 
accustomed to look upon as varieties as species of equal rank ; 
while others, notably Keller, grade them into subspecies, varieties, 
and subvarieties. Most, however, keep up many more species 
than we do in Britain.
