Viewed from in front these bones show the cnemial crest in M. 

 oeellatus more abruptly thrust over toward the outside and the distal 

 condyles less widely separated, although the tunnel under the osseous 

 bridge is larger. In all these respects, the affinities of the fossil species 

 are with Pavo rather than with Meleagris. Beyond these points there

Fig. 2. Curve suggesting the relation of Parapavo (3) to the living Pavo (1) 

 and Agriocharis (2). e.g., In the character of its hypotarsus, Parapavo is more 

 remote from Agriocharis than is Pavo, in the nature of the spur, it is intermed- 

 iate but approaches closely to Agriocharis, in elevation of the spur it is again 

 intermediate but closely approximates Pavo, etc. Values approximated only. 



are no differences between the birds as known by the tibiotarsus. Adult 

 specimens of both sexes yield the following measurements :

Femur. — Several points of difference are to be noted on comparing 

 the femur in the living peacock and the ocellated turkey. Proportions 

 are again reversed and Pavo is found to be the stouter. The stoutness 

 may however be due to a greater degree of pneumaticity. Several
