hairs ; skull short and round ; audital bulhe small, flat and broad ; nasals, 

 taken together, cone shaped (the nasals of Fells, taken together, are 

 broadly truncate posteriorly) ; no distinct lobe on inner side of smaller 

 upper premolar. 



Subgenus LYNX Rafinesque. 



Feet and hands very large, the pads small ; tail very short ; pelage 

 long and loose ; ear with long pencil of hairs (even in the very young 

 kittens) ; skull broad ; rostrum wide ; audital bullse very small and flat ; 

 palatal exposure of presphenoid broadly flask shaped (Fig. 1) ; anterior

of Lvn.v. of Cetvaria. 



condyloid foramen not confluent with foramen lacerum postering ; maxilla 

 separated from nasals by the meeting (or nearly meeting) of the descend 

 ing arm of frontal and ascending arm of premaxilla ; canine teeth slender ; 

 lower molar tooth very large. 



Subgenus CERVARIA Gray. 



Feet and hands small (in floridanm} to medium (in nift'it*} the pads 

 large ; pelage full but close ; tail medium (longer than in Lynx] ; ear with 

 a short pencil of hairs ; skull narrow ; rostrum narrow and ' nipped in ' 

 from sides ; audital bullse deep and long ; palatal exposure of presphenoid 

 strap shaped or slightly triangular (Fig. 2) ; anterior condyloid foramen 

 confluent with foramen lacerum posterius; maxilla touching nasals for 

 some distance (much as in genus Felis) ; canine teeth strong ; lower molar 

 tooth small. 



In North America the subgenus Lynx contains the northern species 

 and the subgenus Cervaria the southern species. The same is probably 

 true of the Eurasian members of the genus Lynx, although I have been 

 unable to find a description of the skull of any of the more southern 

 species. Mr. True examined some skulls of the Swedish Lynx and found 

 that it belongs in the restricted subgenus Lynx. 



The subgenus Lynx is represented in eastern North America by two 

 forms : 



1. Lynx canadensis (Geoff.) occupying the whole of Boreal North 

 America from Maine and northern New York to Alaska, but now very 

 rare and apparently becoming extirpated in the east.
