The outer face of the crown ha^ two or more obhquely directed striae 

 that do not extend to the apex of the main cusp. Two teeth (pi. 20, 

 fig. 2) have a hghtly denticulated carina on the posterior face of 

 the crown and a small tubercle at the basal angle; the enamel is 

 smooth, not rugose. The external carina does not bifurcate on either 

 tooth. 



As regards most of the anterior teeth, the crowns are anteropos- 

 teriorly flattened, the more or less conical apices of the main cusps 

 are incurved, and the enamel is rather smooth internally. The 

 anterior and posterior faces are fiat, as if the adjoining teeth were 

 crowded or touching one another in the tooth row. On some of these 

 teeth there is one long and occasionally two or more shorter striae on 

 the outer face of the crowns curving in the direction of the apex. 



Immediately below the enamel on the base of the crown and above 

 the enlargement, the root on some of the teeth is slightly constricted. 

 The tapering and variously shaped roots of most of the teeth are 

 more or less curved and most of them are strongly bent backward 

 near their extremities. The majority of these teeth have the apices 

 of the crowns, as well as some of the cusps, well worn. On some of 

 the teeth, portions of the enamel surface were chipped off during 

 excavation, and on others the enamel was worn off prior to burial. 



A short section of the left mandible has three molars in place, the 

 posterior one being probably the last of the series and the smallest. 

 This tooth has the summit of the crown broken off, but it is decidedly 

 smaller than either of the other two. The crown was small and no 

 cusps were present. The two teeth in front of this tooth, each of 

 which has the apex of the main cusp worn off, had small curved crowns 

 with a well defined cusp on the posterior face of the crown. The 

 second tooth possesses, in addition, four minute tubercles on the 

 anterior face, and the third tooth has a cluster of tubercles on the 

 internal face. 



A 136 mm. section of the maxillary has three teeth in place, but all 

 three have the crowns broken off. These three teeth occupy an inter- 

 val of 27 mm. Although the remainder of the alveolae are incom- 

 plete, it is evident that eight teeth were located in an interval of 

 80 mm.
