diameter than is shown in the ramus delineated on Plate V of Leidy's 

 paper, and is also too narrow to correspond with the upper jaw illus- 

 trated on Plate III of the same paper. Furthermore the alveolus of 

 the second tooth in the present specimen is further forward and the 

 ramus of this region is shallower than represented in Prof. Leidy's 

 illustrations of Megalonyx jeffersonii. The transverse diameter of the 

 symphysis and the distance between the canine molar and the suc- 

 ceeding tooth of No. 3952 agree better with Megalonyx leidyi found in 

 McPherson County, Kansas, and described by Dr. Josua Lindahl.* 

 The specimen recently obtained by the Carnegie Museum may pos- 

 sibly belong to an unpublished species, but, as the specimen is rather 

 inadequate as a type, I refrain from adding another species to those 

 already proposed. The number of species of this genus of North 

 American Ground Sloths, based upon somewhat limited materials 

 indicates either that there were many species, or that there was a wide 

 range of individual variation.

The first upper premolar and the greater portion of the pedicel of an 

 antler were found by different parties in the bank of the cave-in at 

 Saltville. These specimens are now the property of the Saltville High 

 School. Mr. H. L. Crowgey, in charge of the school, kindly submitted 

 the specimens to the writer for study. 



The portion of antler, which I take to be the pedicel, has very nearly 

 the size of that of a fully adult moose, but is longer. The long pedicel,
