are not very considerable, although very constant, nor, 

 excepting in that of size, very obvious on a casual ex- 

 amination. 



The head is long, the occiput large and rounded, the 

 muzzle very tumid, and furnished with long stiff hairs. 

 The mouth opens straight and wide ; the upper incisors 

 are extremely small, distant, and early deciduous ; the 

 inferior ones are broad at the crown and three-lobed. 

 The anterior nasal leaf is horizontal, shaped like a horse- 

 shoe, anteriorly emarginate, formed of three concentric 

 elevations, the inner one thickened and forming the walls 

 of the depression in which the nostrils are situated. 

 Between the latter rises a prominent cup-like process, 

 somewhat elongated posteriorly, its exposed surface 

 being broadest anteriorly, and presenting a deep cup, 

 whicli is divided equally by a vertical septum ; about the 

 middle this process is somewhat contracted laterally, 

 but it again expands to nearly its former breadth, and 

 terminates posteriorly in a short but rather acute point. 

 The posterior or frontal leaf is as broad anteriorly as the 

 Horse-shoe, but tapers up the forehead to a point, from 

 which descends a mesial ridge, which divides before it 

 reaches the cup-like process, each fork extending to the 

 posterior end of the horse-shoe ; from this ridge spring 

 on either side two horizontal septa, thus dividing the 

 leaf into six irregularly formed cells. The whole of 

 this part of the facial crest is ciliated with stiff hairs. 

 The ears are rather large, broad at their base, with the 

 apices somewhat pointed, and turned a little outward ; 

 the outer margins produced along the sides of the face 

 towards the corners of the mouth, and forming in the 

 front of each auditory opening a kind of rounded lobe, 

 which appears capable of closing the ear ; from their 

 outer margin extend about ten or twelve transverse
