long and more or less slender; their principal characters are seen 

 in Fig. 6 of the Plate. The fibula is free, and it extends but two- 

 thirds down the side of the nearly straight shaft of the tibio-tarsus. 

 The latter presents distally in front the little 'osseous bridge,' 

 spanning obliquely the groove for the tendons which pass there in 

 life. With respect to their extreme lengths, the femur measures 

 3.95 cms.; the tibio-tarsus 5.5 cms., and the tarso-metatarsus 3.0 

 cms. 



In a former paper I have presented the affinities of Edopistes 

 migratorius, and this will obviate the necessity of my touching 

 upon this side of the subject in the present connection, which 

 pretends to be but a brief sketch of this fine representative of the 

 Columbce which will shortly be extinct.

Fig. 1. Skull and trunk skeleton; right lateral view, with bones all 

 in situ. 



Fig. 2. Circlet of sclerotal plates of right eye, with the dried enclosing 

 membranes of the globe attached behind. 



Fig. 3. Hyoid arches, seen from below; the cornua are drawn together, 

 and the glosso-hyal is in cartilage. 



Fig. 4. Right pectoral hmb, viewed upon its palmar aspect, with all 

 the bones in situ. 



Fig. 5. Left humerus, seen upon anconal aspect. 



Fig. 6. Left pelvic limb, inner or measial aspect, with all the bones 

 in situ. The osseous patella is minute and a calcaneal sesamoid of some 

 size is to be seen above the hypotarsus.
