This species was founded upon a tooth of comparatively large 

 size presenting the characters noticed in Part I. Referring the 

 undermentioned specimen to this species on account of its relatively 

 large size and its geological horizon, it will be further characterized 

 by its elongated metatarsals, in which the second was much longer 

 than the fourth, both of these bones having their antero-internal 

 borders rounded, while the distal surface of the fourth is com-
