‘Elurodon wheelerianus lurodon wheelerianus 
Elurodon hyzenoides ?Brachypsalis hyzenoides 
Canis brachypus Cynodesmus brachypus 
Frias. 1-3. Mlurodon wheelerianus Cope, 1874. Upper and lower jaws, Amer. Mus. No. 8307, 
from Republican River bed of Red Willow Co., Nebraska. About three-fifths 
natural size. Fig. 1, external view of upper and lower jaw; fig. 2, inferior, fig. 2a, 
anterior view of maxilla; fig. 3, superior view of lower jaw. 
The second upper molar, not figured here, was subsequently found among the 
fragments and fitted to place. The first molar is incorrectly drawn. The speci- 
men was refigured in 1904, Bull. Am. Mus. Nat. Hist., vol. XX, pp. 250-251, figs. 
3 and 4. 
lia. 5. ?Brachypsalis hyenoides (Cope, 1881). Upper Jaw, type specimen, Amer. Mus. No. 8338. 
Republican River bed, Driftwood Creek, Hitchcock Co., Nebraska. Natural 
size. 
This species appears to be of Mustelid affinities as shown in the form and con- 
struction of the teeth, especially of pt and m!, although it retains a functional m°, 
as in the Canidee. It may be the upper dentition of Brachypsalis, which accords 
in the proportions of molar and premolar dentition. 
Pias. 4&7. Cynodesmus brachypus. Parts of the type skeleton figured on Pl. CXIXb. Figs. 
4, 4a, superior and inferior views of axis; fig. 7, astragalus, superior, inferior and 
external views. 
Fic. 6, unidentified.
