386 Dorothea M. A. Bate — New Artiodadyle from Majorca. 



skull is characterized by what raay be described as a general 

 • shortening ' both before and behind the orbit, the position of which 

 is very high, while its margin is slightly prominent. The lachrymal 

 is short and wide, and the portion of the malar situated in front of the 

 orbit is greatly reduced, causing the eye to be placed very far forward. 

 The opening of the auditory meatus is extremely small. Two 

 roughened projections occur on the upper border of the foramen 

 magnum. The horns, which arise entirely from the frontals, are 

 short and circular in section, the one preserved in the figured specimen 

 measuring 49 mm. (incomplete at tip) in length and 50 mm. in 

 circumference at its base.

The cheek-teeth series measures antero-posteriorly about 48 mm., 

 the upper series being shortened by the presence of two premolars only, 

 by the second molar being very much smaller instead of nearly equal 

 in size to the third, and by the first molar consisting of only one pair 

 in place of two pairs of crescent-shaped columns. Only one premolar 

 is present in the lower jaw, making the number similar to that 

 obtaining in many rodents. Therefore the dental formula of 

 M. balearicus is as follows : — 



i. ? p.m. 2. m. 3. 



i. 1. p.m. 1. m. 3. 

 The ventral border of the massive mandible is convex throughout, 

 its length causing the anterior teeth to project upwards to an extent 

 that suggests that the animal's nose must have been very short. The 

 symphysis of the mandible, apparently, was very strong. The two 

 large rodent-like median incisors were doubtless ever-growing, and 

 penetrate the jaw for a considerable distance, beneath the diastema 

 and as far as to below m. 1.
