affinities in the south, principally in Mexico and Central America; while 

 Euphydryas is more nearly allied to other Melitaeidi in the north tem- 

 perate zone. 



So one might proceed from the essentially peculiar to those which were 

 less specialized from their neighbors until the species were reached. All, 

 however, would tell the same story, — The existence before the glacial 

 epoch of a free communication between the north temperate zone of the 

 two worlds ; of the subsequent invasion of this zone by the cold , pushing 

 animal life away from it ; of its later retirement, followed in its train by the 

 animals which pressed upon it from the south. We may therefore con- 

 clude that our fauna is in only a very limited sense endemic, that it was 

 in the first instance derived from the south and secondarily shows its far- 

 away descent from a circumpolar ancestry of warmer days.

To the wall of the old green garden He longed for the peace and the silence, 



A butterfly quivering came ; And the shadows that lengthened there, 



His wings on the sombre lichens And his wee wild heart was weary 



Played like a yellow flame. Of skimming the endless air. 



He looked at the grey geriiniums, And now in the old green garden, — 



And the sleepy four o'clocks ; I know not how it came, — 



He looked at the low lanes bordered A single pansy in blooming. 



With the glossy-growing box. Bright as a yellow flame. 



And whenever a gay gust passes. 



It quivers as if with pain. 

 For the butterfly-soul that is in it 

 Longs for the" winds again I
