The cranium above described is not accompanied by a mandible, bnt 

 has a cervical vertebra and a scapula associated with it in the same block 

 of matrix. 



The mandible of another skull exhibits the followino- characters: 

 There is a well-developed marginal lobe of the posterior cutting edge of the 

 third and fourth premolars as well as a low posterior heel, and a rudiment 

 of an anterior one The heel of the sectorial is shorter than the remaining 

 part of the tooth, and rises to a cutting edge a little external to the middle 

 line; there is a small tubercle at its interior base. The anterior blade-cusp 

 of the sectorial is much lower- than the median, which is conical; the two 

 diverge, diminishing the shear-like character and action of the tooth. The 

 internal cus]) is well developed. The first tubercular is of moderate size, 

 and is a longitudinal oval in outline. The crown supports two low tuber- 

 cles anterior to the middle, of which the external is the larger. The last 

 molar has a single compressed root, and the crown is a longitudinal oval in 

 outline. Its position is on the ascending base of the coronoid ramus, so 

 that the crown is slightly oblique. The masseteric fossa is profound and 

 well defined; its anterior termination is below the middle of the second 

 tubercular tooth. The horizontal ramus is not robust, but is compressed,, 

 and rather deep.
