(21, p. 168) and short (see figs. 15 and 16). The absence of an articular facet for 
mt. III* on the lower tibial angle of the cuboid in the John Day form is also a 
noticeable feature. Bodcherus humerosus differs from Archxotherium ingens by the 
absence of the trapezium and by the fact that the unciform and magnum do not

touch one another dorsally when in position in the carpus.” From both Dinohyus 
hollandi and Archxotheriwm ingens the John Day subgenus differs by a relatively 
greater transverse diameter of the distal end of the femur. 
Additional specimens from the John Day formation will undoubtedly give more 
complete information regarding this proposed genus. Cope states (10, p. 60) that 
the “‘remains indicate an animal of the size of the Rhinoceros indicus. The animal 
is characterized by the massive proportions of the humerus as compared with the 
femur, and by the short robust form of the metapodials.” 
2! The head of mt. III in the type of Bodcherus is restored on the fibular angle, but it was evidently the same as 
in Archexotherium ingens, judging from the absence of the facet on the lower tibial angle of the cuboid. 
22 Cope says (21, p. 171) that the lunar has penetrated so far as to almost divide the second row of carpals.
