XX XIII.—Some Remarks on the British Species of the Genus 
Martes. By T. C. Kyron, Esgq., F.L.S. 
Ir 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; withina 
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
