In the lower jaw a sharp pointed tooth, corresponding with that in the 

 upper jaw, is situated in the same way ; and takes the place of the first in 

 the series. The intervening space between this and the continuous line 

 contains the second or small deciduous molar. The remaining four teeth 

 are placed together, the first of these (or third of the whole series) consist- 

 ing of a similar cylinder, and the three permanent molars as is usual with 

 the Ruminants, being double barrel'd with the exception of the last which 

 is triple barrel'd. Finally, as in the Sheep and Antelopes, the cylinders are 

 well defined, and without any approach to accessary pillars. 



There are two canines in the upper jaw, as we find in another section 

 of the Ruminantia. 



The presence of incisive teeth in the upper jaw is peculiar to the Camel 

 as a Ruminant. Of these teeth there are two, corresponding in position to 

 the outer incisors, and similar in form to the canines. In taking a lateral 

 view of the skull this similarity of form in the incisor, canine, and first 

 molar, gives the appearance of three canines in the upper jaw. 



In the lower jaw there are, as is normal in the family, eight incisors, 

 differing in form from those of other genera ; — the outer ones taking the 

 simple and pointed form as described above, and the six intermediate ones 

 being more regular in proportions than is usual in Ruminants, and having 

 on each side a nick or hollow on the grinding surface. 



The teeth of the Camel then are as follows : 



Upper Jaw — 2 Incisors. 



2 Canines. 



12 Molars, two of which are pointed and have been 

 termed second canines. 

 Lower Jaw — 8 Incisors, two of which are pointed. 



12 Molars, two of which are pointed, and two deciduous 

 at an early age. 

 The chief peculiarities of the skull are — 

 1 . Narrowness of muzzle.
