The present species is only represented by two extremely young- 

 specimens. The careful examination of their crania by Mr. True and 

 myself revealed features considerably different from those of the other 

 species known, but as the U. S. National Museum ])ossesses no speci- 

 mens of exactly corresponding age it has been thought prudent to 

 await the arrival of additional material before expressing any definite 

 opinion.
