VERTEBRATE FAUNA OF THE BLANCO BEDS. 73 



of the incisors, the second overlapping the first, and the third overlap- 

 ping the second still farther. Another peculiarity is the small size of the 

 canine and its separation from the I. iii by a distance of 23 mm. The 

 molars are very flat on the internal face, and the crowns have a relatively 

 smaller transverse diameter than in the PUauclienia spatula. The ramus 

 is much lighter than in that species or than in the camel. 



I excavated the specimen of PUauclienia spatula from the side of a 

 bluff near Mount Blanco, Texas.
