There is much doubt that it is the femur of a true captorhinid, as that group does not occur in the Wichita formation nor in the Illinois beds. The vertebrae of the captorhinids are so characteristic and bones from the vertebral column are so much more abun- dant than from other parts of the skeleton that they could scarcely fail to be recognized if present. The femur is tentatively associated with the humerus described below (No. 3354). There are two types of humeri which are different from forms previously described. The first type, No. 3354 (plate 24, figs, i to 4, fig. 43, a and b), is represented by six good specimens of different size. The group forms a series, the extremities of which might be regarded as belonging to diff'erent species,.
