other hand, is distinctly smaller than in the tragulines, and has 

 no pit ; it articulates with the frontal, maxillary, and jugal, but 

 is separated from the nasal by a small vacuity which is devel- 

 oped at this point, as in the deer and many other ruminants. 

 There is a single large lachrymal foramen placed within the rim 

 of the orbit. The frontals are shorter and broader than in the 

 tragulines. They extend farther behind the orbits, but not so 

 far in front of them as in those animals, and thus are concerned 

 more in roofing the cranial cavity and less in covering the nasal 

 cavity. Except for their smaller size and greater elevation in 

 the face, the orbits have very much the same position that they 

 occupy in Tragulus, their anterior rim being over the first 

 molar. 



The nasals are not preserved in any of the specimens which I 

 have seen. The maxillaries are long and low, especially the 

 alveolar part, which, however, is higher than in Tragulus, and 

 the facial portion which forms the side of the nasal cavity is 

 also higher than in that genus. The palatine processes of 

 the maxillaries are narrow and slightly concave from side to 

 side. The molars are arranged in gently curved lines, which 

 give the hard palate its greatest width at about the first true 

 molar. 



Unfortunately the premaxillaries are broken away in all of the 

 available specimens, so that those very characteristic parts of 

 the skull cannot be described. The posterior nares are situated 

 far back, and the roof is formed by the palatines for some dis- 

 tance behind the last molar, as in the tragulines, but the lateral 

 palatal notches are shallower and wider than in those animals, 

 and the palatines are continued farther forward in the roof of 

 the mouth ; the pterygoids do not extend so far back and are 

 more widely separated from the tympanic bullae. 



The lower jaw is very peculiar, especially for the great 

 breadth of the ascending ramus ; the angle is strongly promi- 

 nent, giving to this region of the jaw a very different appear- 

 ance from that of Tragulus, and somewhat like Cainotherium, 

 but differing from the latter in being regularly curved and not 

 notched ; its margin is also somewhat inflected. The masseteric 

 fossa is deep and placed high up, as in Pcebrotherium. The 

 coronoid process is stout and apparently vertical in position. 

 The condyle is shaped very much as in the chevrotains, but
