surface at first nearly flat, then sloping almost perpendicularly 

 to very rudimentary cingulum ; commissure relatively shorter than 

 in Martes. Lower carnassial slightly more than twice as long as 

 broad, the sectorial portion of the tooth consisting of two equally 

 robust cusps, the lower the paraconid, whose anterior border 

 slopes backward at an angle of about 50°, and the higher the 

 protoconid, the two connected by an abruptly angled commissure. 

 No trace of metaconid other than a barely noticeable thickening 

 in the ridge which extends from apex of protoconid downward 

 along inner side of cusp to cingulum ; a similar ridge at outer 

 side of protoconid and across posterior heel slightly external to

middle. Crushing portion of crown reduced to a mere ledge 

 much wider than long and with scarcely half the area of base 

 of protoconid ; a faintly indicated outer tubercle. Second lower 

 molar subterete, flat, with faintly developed cusp and longi- 

 tudinal and transverse cross ridges, its crown area about equal to 

 that of pm 2 , and a little larger than that of posterior heel of m 2 . 

 Upper molar relatively small, its crown area scarcely more than 

 half that of carnassial, its greatest diameter about two-thirds 

 that of carnassial ; diameter of inner portion of crown slightly 

 greater than that of outer portion, the constriction between the 

 two portions not well defined : cusps essentially as in Martes 

 martes, but paracone and metacone tending to become confluent.
