MR. FRANCIS NICHOLSON ON THE PINE MARTEN lxiii 



breasted variety), The Beech Marten may probably be entitled 

 to be considered a distinct species, on account of the difference 

 in breadth of skull and the shape of the upper molar ; yet it 

 should not be included in the British fauna until an authentic 

 British specimen has been produced. The Beech Marten seems 

 to be a more southern species than its congener, for it does not 

 appear to go farther north than Denmark and the Baltic pro- 

 vinces on the Continent, and is not a native of Sweden.'
