This form was removed from Grallator by C. H. Hitchcock, with the acquiescence of 

 his father, on the following grounds : " First, the short stride of the animal ; second, the 

 thick, Anomoepus type of the foot; and third, the occasional presence of a long heel 

 upon the hind foot." It differs from A. minimus chiefly in the much less divarication of 

 the toes. 



The type is no. ^f, of the Hitchcock cabinet, on red sandstone from Turner's Falls,
