Zoology. 70 BULLETIN OF THE The head of the radius is less transversely extended and more discoidal than in recent dogs, apparently indicating the retention in some degree oi' the power of supination. FELIS. ? Felis maxima, sp. nov. This species is founded upon a well pri'served humerus from the Loup Fork of Kansas. The chief peculiarity of the specimen is its great size, wliich very much exceeds that of any living feline. In construction it closely resembles the humerus of the lion, with some minor differences. The external tuberosity rises high above the head, and is somewhat less rugose; the deltoid ridge is exceedingly broad and massive, and descends far down upon the shaft; the outer condyle for the capitellum of the radius is less decidedly convex; the internal ejjicondyle is very prominent and massive, and is surmounted by a large epicondylar foramen. The presence of this epicondylar fora- men shows that the specimen be- fore us cannot be referred to Smilodon, for the humerus of iS. necator figured by Cope (Ameri- can Naturalist, Vol. XIV. p. 857) has no such foramen. The su- pinator ridge is somewhat liroken, but it appears to have been pro- portionately less robust than in the lion. The following table will exhibit the great size of this specimen. The measurements of the humerus of Smilodon are taken from Cope's figure. Measurements. Smilodon necator. Felis lea. maxima. m. m. m.
