CAKNIVOEA 



upward behind middle. Palate rather narrow, its width 

 between molars equal to about lA times greatest diameter of 

 molar, incisive foramina small, ovate, slightly oblique, at level of 

 front of canine, the minute median foramen slightly behind 

 middle ; posterior extension of palate broader than long, reaching 

 about half way from level of molar to hamular ; mesopterygoid 

 space about a quarter longer than broad, the hannilars short, 

 slightly everted. 



Teeth. — In proportion to size of skull the teeth are larger 

 than in the members of the other genera of Mustclimx. occurring 

 in Europe ; transverse diameter of upper molar much more than 

 half width of palate between molars. Upper incisors forming a 

 straight row separated at each side from canine by a space about 

 equal to transverse diameter of i^ and i"^ together ; crowns strongly 

 compressed, the antero-poscerior diameter fully twice transverse 

 diameter, the anterior face convex, the posterior ccmcave with 



faintly indicated cingulum ; f- slightly 

 larger than i^, P abruptly much larger 

 than the other two teeth together, its 

 crown more than one-third as high as 

 that of canine and with the posterior 

 concavity extending to outer basal 

 portion. Mandibular incisors smaller 

 and lower than the upper teeth, their 

 crowns projecting obliquely forward, 

 the root of i^ implanted in jaw behind 

 level of the other two ; crowns ob- 

 scurely bifid, the outer lobe smaller 

 than the inner ; crov/n area of z\ 

 j.j(j 79 about one-third that of the com- 



Martes martes. Teeth. Nat. size, pressed i^ Or the subterete i^. Canines 



with no special peculiarities ; diameter 

 of the upper tooth along alveolus equal to one-half width of 

 palate between canines, that of lower somewhat more ; shaft 

 of upper tooth with posterior longitudinal ridge, and an antero- 

 internal ridge which near base curves backward across inner 

 side of shaft nearly to base of posterior ridge ; cingulum barely 

 indicated ; shaft of lower canine directed a little forward at 

 base, a little backward beyond middle, the anterior profile 

 strongly convex, the posterior equally concave ; surface of 

 enamel, especially on basal half of tooth, much roughened by 

 longitudinal wrinkles. Anterior premolar both above and below 

 single-rooted, small (crown area about equal to that of i^ and i^ 

 together), subterete, the height of the single ill-developed cusp 

 scarcely equal to diameter of crown in pm^, much less in pm^. 

 Other premolars, except upper cai^nassial, two-rooted, compressed, 

 the outline of crown triangular when viewed from the side, with 

 apex slightly in front of middle of tooth. Cx'own area of p)m'^ 

 about three times that oiprn^ ; outline of ci'own flattened-elliptical
