432 CARNIVORA 



M. imtoriiin. In fully adult individuals the postorbifcal breadth 

 is noticeably less than that of rostrum or interorbital region. 

 Viewed from below the most striking feature in general outline 

 of skull is the shallowness of the emargination between mastoid 

 process and base of zygoma. Tip of hamular in contact with 

 bulla, a peculiarity due principally to the general shifting forward 

 of bulla with regard to glenoid region. 



Teeth. — As compared with those of Mustela jmtorlns and 

 MusteJa erminea the teeth are through- 

 out relatively heavier and the cusps 

 more elongated. Height of upper 

 canine slightly more than depth of 

 rostrum, instead of decidedly less than 

 rostral depth as in Mustela imtoriuH. 

 Upper carnassial with broader antero- 

 internal projection than in M. jytitorlus, 

 and upper molar set more obliquely to 

 main axis of skull. Lower carnassial 

 strikingly different from that of all 

 ^jg g_ species of Mustela in the presence of 



a well developed third cusp on anterior 



\ nrmela jieregusna. , , , /. /. i j i , i <. 



Teeth, x u. elevated portion oi tootli, the form ot 



which is thus essentially as in the 

 martens. Interrelationships of small premolai's much as in 

 Mustela putorim. 



Measurements. — Adult male and female from Malcoci, Do- 

 brudscha, Roumania (from well-made skins) : head and body, 380 

 and 350; tail, 160 and 160; hind foot, 45 and 40; ear, 25 

 and 23. For cranial measurements see Table, p. 431. 



Specimens examined. — Three, from the neighbourhood of IMalcoci, 

 Dobrudscha, Roumania (B.M. and U.S.N.M.) ; also others from various 

 localities in Asia. 



BemarJcs.—Vormela psregusna is so well characterized both 

 cranially, dentally and externally as to require no detailed com- 

 parison with other European carnivores.

Sub-Family GULONIN.^. 



Geographical flisirihution. — iSTorthern forested portions of the 

 Nortliern Hemisphere. 



Characters. — Dentition essentially as in the Miistelinse but 

 much less trenchant, the small premolars opposite and not capable 

 of shearing action, the points of all but j>m^ and pm^ widely 

 separated when jaws are closed ; upper carnassial very robust, 

 its posterior cusp broad, almost 1^ at -topped, its height much more
