Another specimen in the Peabody Museum demands 

 consideration, for it not only represents a new species of 

 Homogalax Hay, but occurs in a totally different geologi- 

 cal horizon from that of H. bridgerensis described above. 



H. uintensis, as compared to H. bridgerensis, is much 

 larger. The third upper molar is not so perfect a paral- 

 lelogram in form, although it too is greatly elongated 

 along the diagonal through the paracone and hypocone. 

 The antero-posterior diameter is large compared to that 

 of H. bridgerensis. The metaloph forms a continuous 

 straight ridge with that part of the ectoloph leading to the 

 paracone (antero-exterior). This cone is prominent, 

 especially on M 3 , while the double parastyle is very small. 

 On M 2 this style is much larger. Each upper molar has a 

 minute crista and all are notable for their short posterior 

 side. 



In the lower dentition, one sees that the heel of the last 

 molar, although broad, is not definitely divided into two 

 cusps. The third premolar shows a distinct separation 

 of the metaconid (or deuteroconid) and sharp grooves 

 separating the elements of the tooth.
