stout but not very deep with a well rounded border and an 

 uncoossified symphysis ; the jaw increases in depth in the 

 Wind River species (P. nunienus, Fig. 22). Many portions 

 of the skeleton have been described by Cope, including meta- 

 carpals and digits, also a clawed terminal phalanx (as in the 

 second digit of the lemuroid pes) ; unfortunately we must 

 consider this association as somewhat doubtful. The femur 

 (P. tutus) has a pit for the ligamentum teres and a long crest 

 below the great trochanter. The radius has an oval head. 

 The scapula has a prominent coracoid process. The head 

 of the astragalus (P. jarrovii, Coll. U. S. Nat. Mus.) is convex 

 and prolonged beyond the calcaneum. The caudals are long 

 and slender. 



I. Wasatch (Sparnacien, Ypresien) Stage. 



Common Characters. — Superior molars more or less triangu- 

 lar, with rudimentary hypocone, without mesostyle. 



(Sp. 35) Pelycodus jarrovii Cope. — This, the first species 

 described, is represented by a rather imperfect type in the 

 National Museum.

(Sp. 38) Pelycodus frugivorus Cope. — Includes the smaller 

 and more primitive Wasatch specimens in which there is a 

 variable rudiment of the hypocone in the upper molars (see
