The fragments of horns both include the burr. This is not very prominent, 

 and the beam is quite smooth. There are indications of tines, but they are broken 

 off at the base. In the shorter fragment a tine is given off on the internal side, 

 but it is broken off near the base, and the beam beyond its base is also lost. In the 

 second fragment the position corresponding to the internal tine is split away. 

 Above it the beam is somewhat compressed anteroposteriorly, and sends off a smaller 

 tine directly anteriorly. The beam in both is entirely smooth.

The smoothness of the beam of the horns distinguishes this species from the 

 existing species of Cariacus of both North and South America, and resembles the 

 condition seen in the species of Coassus, where the horns are unbranched. The 

 inferior tine originates nearer the burr than in the known species of Cariacus, while 

 the anterior tine is present only in species (C campestris), where the interior tine 

 is absent. The larger beam preserved shows no tendency to an anterior curvature 

 such as is present in most of the species of the genus. 



This species was probably of about the same size as the Virginian deer. 



Cariacus sp. 



Portions of four or five deer indicate a species different from the last, and so 

 much like C. virginianus, that it is not possible with the material at hand to dis- 

 tinguish the two. The first individual is represented by the left pm-L and m- 2 - and 

 and the right pm^ ; No. 2, by a right mandibular ramus containing six molars, the 

 last about to be erupted, and the last deciduous remaining in place ; No. 3 includes 

 the m T _2 of the right side ; and the others fragments of molars. 



The proportions of the superior molars and premolars are as in C. virginianus, 

 and the valleys of the premolars are interrupted by the branches from the inner
