NO. _7 W EXTINCT AMERICAN ELAND G1DLEV 3 



While not constituting- the only discovery in America of remains 

 representing Old World antelopes, such occurrences arc very rare, 

 and this seems to he the only one in which the relationship is appar- 

 ently especially close. Heretofore only two forms of seemingly 

 undoubted Old World affinities have been reported, and these from 

 a single locality as follows: Llingoceros alexandrce Merriam and 

 Sphenophalos nevadanus Merriam, lower Pliocene of Virgin Valley, 

 Nevada, founded on a few fragments including portions of horn 

 cores. 1 These antelopes exhibit seemingly undoubted strepcisserine 

 affinities, but as yet no associated material including teeth is known. 

 A possible Hippotragine antelope, Neatragocerus improvisus Mat- 

 thew, 2 lower Pliocene of western Nebraska, founded on a horn-core, 

 probably records a second occurrence, although this form may prove, 

 when better known, to belong rather to the goats than to the ante- 

 lopes. A third form referred to the antelopes, but which apparently 

 is more antelocaprine in affinities, is the small artiodactyl from the 

 famous Pleistocene deposits of the La Brea ranch recently described 

 by Taylor as doubtfully belonging to the genus Capromcryx. 3 This 

 species is certainly not closely related to any of the living antelopes. 



The exceeding rarity in American deposits of any fossil remains 

 of Old W^orld antelopes makes the more startling and unlooked-for 

 this appearance in Pleistocene deposits of the eastern United States 

 of the remains of an antelope apparently not generically distinguish- 

 able from the eland, now living only in Africa south of the Great 

 Sahara Desert.
