XXXIII. — Some Bemarks on the British Species of the Genus 

 Martes. By T. C. Eyton, Esq., F.L.S. 



It has been long, and is now, I believe, a disputed point between the 

 writers on British Mammalia, whether or not two species of Marten 

 exist in the British Isles ; thus, Mr. Bell in his excellent ' History of 

 British Quadrupeds' gives them distinct; while, on the other hand, 

 Mr. MacGillivray in the 'Naturalists' Library' is of the opposite 

 opinion. With a view of doing something towards setting this 

 question at rest, I requested several persons living in neighbour- 

 hoods where Martens are found to obtain some for me ; within a 

 short period I have received four specimens, one of which ex- 

 ternally presented all the characteristics of the true Pine Marten, 

 having the bright yellow breast of that species ; another agreed 

 with the descriptions of the Common Marten, was larger than the 

 last, and had a white breast. Both of these I had made into ske- 

 letons. The other two specimens presented an intermediate cha- 

 racter, having the breast slightly tinged with yellowish : I have 

 merely kept the cranium of one of these. I have no hesitation in
