the foot which made it was evidently digitigrade. The footprint 
from Kegworth is not Chirosaurus hereulis (2). 
This footprint bears some resemblance to the two groups of 
Chirosauroid prints which Mr. H. C. Beasiey has classified as 
Group K (1, 8) and Group P(4). It resembles the prints of Group K 
in general outline and two of its digits are curved and also longer

than wide, but it differs from that group as the digits are not 
triangular in section, and two of them are neither greater in length 
than the width at the roots nor are they curved. It resembles those 
of Group P in that there is evidence of the posterior end gradually 
merging into the surface of the stone and also in the comparatively 
short, quickly tapering digits; but it differs from that group in that 
neither the two outer toes are equal nor are the two inner, and the 
two digits III and IV curve inwards. 
It may be that the prints of these two groups were made by 
aborted forms of some of the feet which made the five-toed prints in 
Mr. Beasley’s Group A, but at present this is only surmise. So for 
the present it is advisable to separate these four-toed prints in 
a group or groups apart, and as this Kegworth print is intermediate 
in character between the Groups K and P, I propose to label it 
Chirosauroid footprint, Form KP (Beasley), from the Keuper of 
Kegworth, Leicestershire.
