PLEISTOCENE VERTEBRATES FROM CUMBERLAND CAVE 



85 



Myiohyus hrowni Gidley (Gidley, 1920b, pp. 675-676; Brown, 1908, 

 pp. 200-202, pi. 24) is a more slender and elongate jawed form than 

 M. exortivus, although according to the illustrations given by Brown 

 P2 in the Conard Fissure specimen is molariform, or nearly so. 



A pair of fused metatarsals in the Cumberland Cave peccary 

 material is referred to Myiohyus. These bones are distinctly longer 

 and slenderer than in Platygonus.
