 Teeth (ezcept pj) broad, 

 stout, cusps strong, conical, 

 cingulum well developed on 

 the upper t^eth, with tendency 

 to form accessory cusplets. 



m' broader than long, shorter 

 than m^. 



m, absent. 



p' quinque-ciispid, with a 

 special root supporting the 

 two inner cusps. 



p^ as large as m^, the two 

 inner cusps (6 — 7 Winge, pr. 

 and hy. Osbom) form more 

 than */, of the tooth, they 

 are supported by a very strong 

 root which is placed mainly 

 under the anterior cusp. 



p, strong, with one rather 

 blunt cusp. 

 P4 quinque-cuspid. 



Number of vertebræ 7 c, 

 14 d., 61., 38.. 18 caud. 



Scapula Bmall, the supra- 

 scapular border almost not ex- 

 tending beyond the ridge run- 

 ning along the glenoid border. 

 Glenoid and coracoid border

broad, extremely stout, cusps

 tendency to form not only ' 

 cingulum cusps, but also ae- ; 

 cessory cusplets in the valleys i

m' elongated, longer than m^. 



mg only a little reduced. 



p' quinque-cuspid, but the 

 two inner cusps are widely 

 separated cingulum-cusps with 

 no special root. 



p* smaller than m*, the inner 

 cusps form only ^/gof the tooth, 

 only the posterior one is sup- 

 ported by the weak root and 

 is thus the true "heel-cusp" 

 (Winge 1. c), the anterior is a 

 cingulum-cusp with no root. 

 (Bardenfleth 1. c.) 



p, strong, with three sharp 

 cusps. 



P4 tri-cuspid, with sharp 

 edgea. 



Number of vertebræ : 7 c, 

 13 d., 41., 68., 7 caud. (at 

 least) (according to Gervais). 



The Bupra-scapular border of 

 the scapula forms a very small 

 area behind the upper Vs ^' 

 the ridge running along the 

 glenoid border. Glenoid and 

 coracoid border somewhat di- 

 verging.

 Premolars reduced, p *II?-

often wanting, molars stout, 

 somewhat broadened, especi- 

 ally m^— 3 and m2— s, which 

 show a tendency to form cin- 

 gulum cusps and accessory 

 cusplets and folds between the 

 ordinary ciisps. 



m* elongated, longer than m^ 



mg somewhat reduced. 



p' rudimentary, with one or 

 three small cusps, often ab- 

 sent in adult animals. 



p* reduced, much smaller 

 than m*; the "heel-cusp" is 

 placed far back, but connected 

 with the anterior outer cusp 

 (5 Winge) by a cingulum ridge 

 which sometimes develops a 

 small cusp. (c in pi. I 9.). 



Pi reduced, often absent. 



P4 reduced, with 1 — 3 irre- 

 gular cusps. 



Number of vertebræ : 7 c., 

 14— 16d., 6— 5L, 4— 6«., 9—10 

 caud. 



The supra-acapular border 

 forms (in some species) a pro- 

 minent area behind the ridge 

 running along the glenoid bor- 

 der, this area occupying the 

 upper half of the glenoid bor- 

 der (it is rather small in T. 

 omatus, Mdwrøus a.o.). Glenoid 

 and ooraooid border often nearly 

 pumlleL 



Head not rather heavy.
