. Bulletin of the Department of Geology. Geology. 390 University of California Publications. [Geology GYMNOGYPS AMPLUS, n. sp. Type specimen no. 9834, Univ. Calif. Col. Vert. Palae. Right tarsometatarsus from Samwel Cave. Tarsometatarsus very broad as compared with Gymnogyps californianus (Shaw) ; foot set inward on the shaft so that the median line of the shaft falls outside the center of the foot. The establishment of this new form of condor is based on its comparison with a single Recent specimen in addition to a series of fourteen tarsometatarsi from the Pleistocene of Rancho La Brea, in which beds the bird occurs abundantly in a phase considered to be identical with the Recent In this splendid series there is no individual which approaches in breadth of shank the dimensions dis- played by the specimen here described. It is to be expected that a bird of the large size to which the condor grows would vary to a considerable degree. However, the extremes of variation ex- hibited by the series referred to above fail by a wide margin to include the cave form within its limits. As mentioned also in the previous discussion of that series, the difference between Sarcorham- phus and Gymnogyps as displayed hy the tarsus is almost entirely one of rela- tive width. Cathartes, Gymnogyps, Sar- corhamphus, and Catharista form a grad- uated series in this respect, passing from broader to narrower tarsus. The species here proposed displays a degree of flat- tening equal to or in excess of that seen in Cathartes. Unfortunately the proximal end of the tarsometatarsus is not preserved,. Fig. 2.
