They are in their posterior margin strongly denticulated, and resemble in this respect those of an Ox. The number of such palatal ridges is also about the same in tbe O x ; but in Ovis (11-12) and Capra (11) the number is smaller, and there are no denticulations, or only traces of such, in the foremost ones. In Capreolus 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 Ovibos 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 Fig. 2. ^*SJI*- ** m* '• ^ ^ v ^ £>*««, *»„ •gmttemi ir- •iff, • (.,-</' *\f- «*>, , ' ' T . * UFf. r rtB* Palatal and buccal surface of the Musk-ox. furrow from the adjoining parts.
