Osteologically, among the Cervide, the skull presents features 
which correspond in great measure with their geographical distribution ; 
and, dentally, the peculiarities of the third lower premolar are most 
instructive. The consideration of these latter I hope to be able to 
bring before the Society on a future occasion, when my material has 
become more abundant. 
In all Old-World Cervide examined by me, with the exception of 
the Reindeer, the vomer is not so much ossified as to divide the pos- 
terior osseous nares into two distinct orifices, whilst.in Rangifer 
tarandus and all the New-World Deer, excepting Alces machlis and 
Cervus canadensis, it is so. I have seen most of the skulls of the Deer 
which are to be found in the superb osteological collection of the 
British Museum; and it is upon the study of them that this genera- 
lization is based. In the following species the vomer is completely 
ossified behind, so as to separate off the two posterior nares in the 
macerated skull : 
Cervus pudu. Cervus leucotis. 
campestris. antisiensis. 
columbianus. virginianus. 
leucurus. mexicanus. 
Neither in Alces machlis nor in Cervus canadensis is the vomer so 
extended posteriorly. The condition described is represented in fig. 24, 
which is from the skull of Cervus virginianus.
