<>n5y the median, in others the lateral part is developed. Thev 

 are in their posterior margin strongly denticulated, and resemble 

 in this respect tho?e of an Ox. The number of such palatal ridges 

 is also about the same in the Ox ; but in Ovis (11-12) and Copra 

 (11) the number is smaller, and there are no denticulations, or 

 only traces of such, in the foremost ones. In Capreohts I have 

 counted 12-13 distinct palatal ridges, of which the anterior ones 

 are striated and crenulated. In this respect Ovibos resembles Bos 

 more than the others. 



The papilla palati of Ovilws is more rounded than in Bos and 

 Ovis, not anteriorly, but only posteriorly, and especially on the 

 sides, where the ducts from Jacobson's organ open, divided by a
