The femur (text-fig. 41) is a very much smaller bone than the humerus, the relative lengths of the two being about as 2 to 3, while the difference in bulk is still more striking. The proximal end of the bone is very massively constructed compared with Text-fig. 39.

If, as in the description of the fore limb, we assume that the palmar face of the paddle looks downwards and backwards, making an angle of about 45° with the vertical, then in text-fig. 41, C, which represents the proximal end of the right femur, the line a-b shows the direction of the paddle, a being at the top. The border marked is ventral, vllile is anterior. The large trochauter-like ridge forms the postero-inferior angle on the border,.5, is at the top. As in the case of the humertis, the upper end
