three teeth separated 1)y a diastema; dentary teeth 21-23 ^'^ 

 number, usually 21, scaphiodont, uniformly increasing in size 

 anteriorly, the first few being nearly twice as long as the last ; 

 palatines 13-16, usually 13 or 14, only slightly longer anterior- 

 ly; pterygoids 18-25. usually 22-23, scaphiodont. 



It should be pointed out here that it is entirely possible that 

 this new form, here given the status of a species, may later be 

 found to l)e a subspecies of schotti. It is impossiljle to deter- 

 mine this, however, until specimens from critical localities are 

 available.
