No. 2324. PECCARIES FROM CUMBERLAND CAVE—OIDLEY. 659 



further differs from P. vetus in the shorter snout, as indicated by 

 the relatively shorter symphysis of the lower jaw; and by the ap- 

 parently much greater relative width of the palate. This last char- 

 acter is suggested in Duges's figure, and is borne out by the relatively 

 wide distance between the dental series of the lower jaw of the 

 type specimen. 



PLATYGONUS LEPTORHINUS Williston. 



Type. — Williston did not designate a type specimen for this spe- 

 cies, hence the nearly complete skeleton of an adult female first men- 

 tioned and figured by him may be selected. Location of type (?) 

 Kansas University Museum. 



Type locality. — Goodland, near Fort Wallace, western Kansas. 

 Described by Williston in 1894.^ 



Diagnosis. — About the size of P. compressus; length of cheek-tooth 

 series 75 to 80 mm. (see Williston) ; proportions and general appear- 

 ance of teeth about as in that species. It differs from P. compressus 

 in having a deeper and shorter jaw angle; in the relatively less 

 antero-posterior expansion of the coronoid process; the more pro- 

 cumbent position of the lower incisors giving a decided angulation 

 to the chin, and in the relatively greater vertical expansion of the 

 zygomatic processes. In P. leptorhinus this expansion in the female 

 skull figured is slightly less than the vertical diameter of the orbit. 

 In the male it is nearly one and one-half times the vertical diameter 

 of the orbit. 



PLATYGONUS CUMBERLANDENSIS, new epecies. 



Type. — A nearly complete male skull associated with a portion of 

 the lower jaw ^ (Cat. No. 8146, U.S.N.M. Coll.). Paratype: a nearly 

 complete skeleton of an adult female (Cat. No. 8200. U.S.N.M. 

 Coll.). 



Type locality. — Cave deposit about 4 miles northwest of Cumber- 

 land, Maryland. Collected by Gidley, June, 1914. 



Diagnosis. — A large species, nearly equalling P. vetus in size. 

 Length of cheek-tooth series, type (male), 94 mm.; paratype (fe- 

 male), 87 mm. Differs also from P. vetus in having a greater 

 relative length of the molars in animals of corresponding age, and 

 in the possession in the upper molars of well-developed intermediary 

 cusps and lophs, which connect at their bases the two principal cross 

 lophs, as in P. compressus and P. leptorhinus. It differs from both 

 these last named species in the much larger size of the skull, in 

 which there is a relatively higher and more backwardly produced 

 inion and a more strongly developed expansion of the zygoma,

* This association is not certain but highly probable, as the jaw portion was found 

 near the skull, and a careful examination of the teeth in the two specimens shows almost 

 exactly the same degree of wear.
