spider was contained among the other spiders received from 

 Newfoundland. It is allied to Epeira cornuta (Clk.) and 

 E. patagiata (Clk.) of Europe, but is, I think, quite distinct 

 from them, and appears to have been hitherto undescribed.

 THE MAP. 



The accompanying map is not intended to show with 

 minute accuracy the present distribution of the squirrel in 

 Scotland, nor the exact extent of the areas populated from 

 each centre. It is merely intended to give a general idea of 

 the Faunal divisions of Scotland, and show the approximate 

 areas populated from the different centres. The small scale 

 of the map forbade any attempt at precise and exact colour- 

 ing, nor indeed can our data, as given in the text, admit of 

 any hard and fast line being drawn, showing the limit of the 

 influence of the outward waves of distribution from the differ- 

 ent centres, nor the points at which waves from different 

 centres coalesce. The map, it is hoped, however, will assist 

 in a general way, to explain what amount of influence each 

 centre has had in repopulating Scotland.

In the latter half of the eighteenth century, the squirrel 

 was introduced from England to the menagerie at Dalkeith, 

 by Elizabeth, Duchess of Buccleuch. This introduction must 

 have taken place, as wiU be seen in the foot-note, not prior to 



* Excluding Dumbartonshire, Stirlingshire, and northward, which districts 

 come to be treated of later.
