of a cranium, discovered by Dr. Carter in the hutles uf Dry Creek Canon. 

 The specimen was broken into many pieces, but tliese have been united so 

 as to give us a good idea of the shape and construction of tlie cranium. This 

 is of remarkable form, and exhibits more resemblance to that of a bear flian 

 to that of its nearer relative the tapir. 



The forehead, as seen in the upper view of the cranium, Fig IG, Plab^ 

 XXIII, forms a long triangle, with the apex prolonged backward and expanded 

 at the summit of the occiput. Its fore part more abruptly widens as it exten<ls 

 outwardly upon the conspicuous postorbital processes. Its surface from the 

 apex forward is strongly convex, but approaching the muzzle between tlie 

 position of the postorbital processes it becomes in the same direction con- 

 cave. Transversely it is nearly straight between the boundaries of the tem- 

 l»oral ibss;e, but is convex between the postorbital processes. The lalter 

 are strong and unusually prominent, trihedral, hook-like projections. Their 

 upper acute border forms the anterior extension of the temporal boundary 

 from the forehead. Their supra-orbital margin curves from the tiice Jiack- 

 ward and outward to the point. Their anterior or facial surface is depressed 

 or concave. 



The postorbital process preserved in the specimen is broken at the end, 

 but is there so narrow as to make it appear that it did not meet an ascending 

 process from the malar l)one as to Ibrm a postorbital arch. The strongly 

 arched supra-orbital border is directed outward with a moderate backw ard 

 inclination, indicating a more forward direction for the orbit than in the tapir 

 and rhinoceros. 



The short postorbital eminence of the malar bone in tlie facial sjiecimen 

 referred to Falatosyops paludosus, and represented in Fig. 51, Plate XVIII, 

 would also indicate that the orbits were oj^en behind in Palset)syops, notwith- 

 standing the great length of the postorbital process of the frontal in the 

 specimen under consideration. 



The l)ase of the muzzle, or the face, between the position of the orbits is 

 broad and convex. 



, Tiic specimen exhibits no evident traces of the sutural conjunctions of the 

 parietals, frontal, the maxillaries, and the nasals. 



The cranial crest separating the temporal fossa; is exceedingly short com- 

 pared with that of the tapir. It is formed by the approach of the temporal 

 l)oundaries, which appear in this position as two ot)tusc ridges squeezed
