A few fragments, which I judge to belong to the fibula, show that 

 bone to have had a heavy shaft. 



The pes is fairly well represented. In its proportions it approaches 

 Vulpavus profectus Matthew, though the metatarsals may possibly 

 be relatively somewhat shorter than in that genus. The tuber of 

 the calcaneum is not long, but is quite heavy, and has an ill-defined 

 groove for the plantar tendon. The lesser process of the distal end 

 is quite widely expanded; on the fibular face of the greater process is 

 located the peroneal tubercle, which is large, and has a groove for 

 the peroneus longus fully as large proportionally as in Cercoleptes 

 caudivolviiliis. There is no facet for the fibula; the facet for the cuboid 

 is triangular in general outline and not as oblique as in Vulpavus 

 profectus, described by Matthew, but is perhaps more nearly like that 

 in Cercoleptes. The astragalus and ectocuneiform were unfortunately 

 not recovered. The entocuneiform is of large size and has a very 

 oblique facet for the navicular. This great obliquity continues in a 

 similar manner downward over the superior fibular face of the 

 mesocuneiform, so that the facet for the entocuneiform and the facet 

 for the navicular on the mesocuneiform form an unusually acute 

 angle. The cuboid is low as compared with Mimocyon, or with such 

 a recent form as Cercoleptes. There is not any evidence of an articu- 

 lation for the astragalus on the proximal tibial angle as seen in the 

 latter genera. The proximal portion of the tibial face has, however, 

 a large rough area, which no doubt joined the navicular, but probably 

 did not come in contact with the side of the head of the astragalus. 

 The facet below this area is plane, subtriangular in outline, of consider- 

 able size, and articulates with the ectocuneiform. The plantar tuber- 

 osity, though quite well developed, is not nearly as large as in Cer- 

 coleptes or Mimocyon, and the groove of the peroneus longus is 

 consequently smaller and shallower than in the latter genera. The 

 articulation for the metatarsals is quite oblique and subtriangular in 

 outline. The metatarsals have apparently a close resemblance to 

 those in Vulpavus profectus, the first being stouter and much shorter 

 than the other four. Mt. V is not present in the material studied. 

 As in the Miacidce, the proximal row of phalanges are long, somewhat 

 depressed, and the shafts slightly curved dorsad. The median row of 

 phalanges are short, with only a very slight indication of asymmetry 

 and at their lower extremities bent slightly dorsad. The ungual 

 phalanges are represented only by the proximal portion of one phalanx,
