Locality 12 (Fig. 2) is in the neighborhood of Watauga, Township 23 N., Range 21 E. Cera- 

 topsian material collected here in 1922 by Philip Reinheimer consisted of "a considerable part of a 

 skull, having the horns i]uite complete. The latter were not less than three feet in length. The 

 frill had been eroded out and lay in many fragments upon the surface." There were also various 

 skeletal parts that were quite disassociated. 4

Locality 13 (Fig. 2) is in the Big Horn Basin. Triceratofs bones were found here and identi- 

 fied by C. W. Gilmore. 5 Hatcher also reports having seen ceratopsian material along the eastern 

 flank of the Big Horn Mountains, about 40 miles south of Buffalo. 



Locality 14 (Fig. 2) comprises a large part of Niobrara County, formerly part of Converse 

 County. This has been the most fruitful of all ceratopsian localities. Most of the collecting was 

 done before 1907 by Hatcher, and by C. H. Sternberg, the account of which has been related in 

 detail by Lull in the first monograph. However, a list of the specimens follows:
