(CARNIVOEA 



an average difference, however, between the Mediterranean 

 animal and that occurring north of the Alps. Two of the 

 specimens from Porlezza are darker than the others, in this 

 respect agreeing with the northern animal. 



MARTES FOINA Erxleben. 

 (Synonymy under subspecies. 



Central and southern Continental 

 coast eastward, and from the 



KiG. 80. 



Larger cheek-teeth of Marten 

 mai-tes (a) and M.foina (0). 

 Nat. size. 



Geographical distribution.- 

 Europe, from the Atlantic 

 Mediterranean to the Baltic. 



Diagnosis. — Third upper premolar with outline of crown 

 nearly biconvex, the outer side occasionally 

 flattened, the greatest transverse diameter 

 at middle ; upper carnassial with inner 

 lobe slender, its diameter in line of tooth- 

 row equal to only about half greatest 

 width of trenchant portion of tooth behind 

 middle of crown ; upper molar not so large 

 as in M. martes, its gx-eatest diameter less 

 than outer length of carnassial, the meta- 

 cone less than half as large as paracone ; 

 external form as in M. martes, but fur 

 of less fine quality ; colour usually more 

 greyish or drab than in 31. martes and seldom with the rich 

 brown tints of the related species, the throat-patch never strongly 

 tinged with yellow. Mammae : 4. 



Skull. — The skull resembles that of Martes martes, but may 

 usually be distinguished by its greater breadth and less depth. 

 Brain-case noticeably wider than high, the general outline when 

 viewed from behind nearly as in 3Tustela erminea and distinctly 

 less elevated than in Martes martes. Interorbital region and 

 rostrum wider than in Magics martes, and concavity of dorsal 

 profile in nasal region much more pronounced. Anteorbital 

 foramen usually smaller than in the related species, though in 

 the same position. In other respects the skulls of the two 

 animals show no tangible differences. 



Teeth. — Except as already pointed out the teeth agree with 

 those of Martes martes.
