This form, while a true Grallator, is 

 (juite similar to Anchisaurijjus dfoiamts, 

 but is distinguished from the latter by 

 the greater projection of the middle toe 

 and the generally cuneiform shape of the 

 foot which is heightened by the bending 

 outward of the lateral claws. 



The type is no. \°, of the Hitchcock 

 cabinet, on red shale from the Lily pond 

 at Turner's Falls. Massachusetts. Fig-

This is very large for a Grallator, but is long of limb and lacks a hallux on all 

 known specimens. It resembles G. cxneatiis, differing from the latter chiefly in .size. 

 It approaches very near Anchisaurlpioi dananHs and may prove to be identical at any 

 rate with some of the specimens referred to that species.
