The reindeer-caribou type, of the genus Rangifer, agrees with American deer in having the vertical plate of the vomer complete, and in having the lower ends of the lateral metacarpals remaining, but, like Cervus, it has a brow-tine to the antlers.
On the whole, as far as I could judge, the females of those Prionidae, in which the sexes differ, are coloured more richly than the males, and this does not accord with the common rule in regard to colour, when acquired through sexual selection. Chalcosoma atlas. Copris isidis. Phanaeus faunus. Dipelicus cantori. Onthophagus rangifer, enlarged.
Onitis furcifer, processes of anterior femora of the male, and on the head and thorax of the female. Onthophagus. Onthophagus rangifer, sexual differences of; variations in the horns of the male. Ophidia, sexual differences of. Ophidium. Opossum, wide range of, in America. Optic nerve, atrophy of the, caused by destruction of the eye.
As there are objections to considering these characters as of family value, arising from the intermediate position of the circumpolar genera Alces and Rangifer, as well as the water deer and the roe, a broader meaning is given to classification by retaining the comprehensive genera Cervus and Mazama, and recognizing the subordinate divisions only as sub-genera.
They were successful in securing thirteen musk-oxen in that neighborhood, and in Bellows Valley they shot a number of the "Peary" caribou, the species "Rangifer Pearyi," a distinct class of reindeer inhabiting that region. On the return of Dr. Goodsell, he told of his fascinating experiences in that wonderland. Leaving the Roosevelt, he had turned inland at Black Cliff Bay.
They are normally absent from all females except those of the genus Rangifer. Most deer have canine teeth in the upper jaw, though they are absent in the moose, in the distinctively American type and a few others. The cleaned skull always shows a large vacuity in the outer wall in front of the orbit, which prevents the lachrymal bone from reaching the nasals. No deer has a gall bladder.
THE CARIBOU, GENERALLY. I think it is not very difficult to forecast the future of the Genus Rangifer in North America, from the logic of the conditions of to-day. Thanks to the splendid mass of information that has been accumulated regarding this group, we are able to draw certain conclusions.
