vomer. Each of the cavities has an opening in the middle of the outer side, 

 between the turbinal bones, into a narrow bony, sinuous tube on each side of 

 the palatine cavity above described, which each has a small narrower 

 opening in the front of the palate behind the cutting teeth and a larger one 

 behind, forming the interior nasal opening. The turbinals are attached to 

 the upper outer surface of the upper nasal cavity, and have a large convoluted 

 lamina on the lower side, and are met by the lower turbinals, the aperture to 

 the nasal tube being between the turbinals. The auricular bulla is cellular 

 internally. This structure is very peculiar, and very unlike the simple 

 nasal ca-saty, direct from the anterior to the posterior nostrils, which is found 

 in the Pig, Phacocheir, and in all the other Pecora and Bellua that I have 

 examined or seen figured, and in them there is an aperture on each side in 

 front of the palate, between the palatine and intermaxillary bones. 

 The section of Dicotijles labiatus is very similar.
