Page 81 - Fossil Mammals of the Wahsatch and Wind River Beds, Collection of 1891; Bull.
Page 227 - Boreal Province. Thus the whole of the so-called 'Great Central Province' disappears. This explains a multitude of facts that are utterly incomprehensible under the commonly accepted zoological divisions of the country. These facts relate particularly to the distribution of species about the northern boundaries of the supposed Central and Pacific Provinces, and to the dilemma we find ourselves in when attempting to account for the origin of so many primary life areas in a country where there are...
Page 278 - ... trill alternate ad libitum. The staccato notes may be continued almost indefinitely, but are very rarely heard more than ten times in direct succession ; it ordinarily occurs three or four times before the repetition of the phrase, but not more than two or three times when the phrase is not repeated.
Page 202 - If these considerations are well founded, the objections of those who study insects or molluscs, for example,— that our regions are not true for their departments of nature — cannot be maintained. For they will find, that a careful consideration of the exceptional means of dispersal and conditions of existence of each group, will explain most of the divergences from the normal distribution of higher animals.
Page 354 - The occipital surface slopes backwards. .. .The facial region of the skull is narrow and elongate. On the outer surface of the maxillary just above the antorbital foramen, there is a deep depression which probably contained a gland. The usual ruminant fossa in front of the orbit appears to be wanting. The orbit is large, and completely closed behind by a strong bar of bone. ...The paroccipital processes were well developed, but there were apparently no auditory bulte.
Page 228 - THE SONORAN TRANSITION REGION. This tract, which, as already stated, comprises the peninsula of Lower California, the State of Sonora in Mexico, New Mexico, Arizona, and parts, not yet absolutely defined, of Nevada, California, Texas, and Florida, is, as far as the Mammalia and birds are concerned, not very clearly differentiated ; the intermingling of northern and southern elements, with a decided preponderance in favor of the former, is very great, and the peculiarities insignificant.
Page 286 - Sci., viii, 1883, 60) freshly killed specimens have "twenty-four fleshy processes arranged in two rows on the front part of the neck, and about twenty more of the same kind form two rows over the head; many smaller ones are scattered over the head. At the point of union of the bill with the head, there is a long fleshy process capable of much erection and distension. Behind this the fleshy scalp is permanently elevated so as to form a flattopped pyramid, with its greatest length from bill to occiput.
Page 346 - S. h. grahamensis is apparently not a very strongly differentiated form, it seems to well warrant recognition, especially when considered in relation to its fairly isolated habitat. While the White Mountains form merely the eastern end of the elevated pine plateau extending westward to the San Francisco Mountains, the Graham Mountains are south of the plateau region, from which they are separated by a comparatively low arid plain. Mr. Price (in letter of October 12, 1894) writes: ' Finding Sriun/s...
Page 202 - Regions so established will be most closely in accordance with those long-enduring features of physical geography, on which the distribution of all forms of life fundamentally depends ; and all discrepancies in the distribution of other classes of animals must be capable of being explained, either by their exceptional means of dispersion or by special conditions affecting their perpetuation and increase in each locality." "If these considerations are well founded...
