Стр. 395 - ... but slight (except beneath the floor of the neural arch), until it falls rather abruptly into the axial perforation. In an (?) anterior dorsal it is as widely excavated at the border as the posterior funnel. Another peculiarity is the absence of the processes of the centrum ; and a small capitular articulation is seen sessile on the border of the cup of two of the dorsals. "The axis* has a singular form, owing to the tubular perforation which continues the posterior excavation to the anterior...
Стр. 392 - Sphenodnn of New Zealand. The bones of the limbs and scapular arches are so decidedly reptilian, and so unlike those of any Batrachia with which we are yet acquainted, that I am disposed to refer them to the former class. And as there are several points in which the fossils resemble the order Rhynchocephalia, I refer them provisionally to that neighborhood. They constitute the first definite indication of the existence of animals of that type in the western hemisphere.

Стр. 396 - ... superior articular facets. • There is no true hypapophysis of the axis, and the only indication of lateral processes is a small articular facet on each side on the lower part of the rim of the posterior funnel. These may have been related to rudimental cervical ribs. The neural arch is broken off. The dorsal vertebrae have their sides somewhat contracted ; in one specimen the inferior face is rounded, in another, which I suppose to belong to a different part of the column, it is longitudinally...

There is no true hypapophysis of the axis, and the only indication of lateral processes is a small articular facet on each side on the lower part of the rim of the posterior funnel. These may have been related to rudimental cervical ribs. The neural arch is broken off. The dorsal vertebrae have their sides somewhat contracted ; in one specimen the inferior face is rounded, in another, which I suppose to belong to a different part of the column, it is longitudinally acute. In this and...

Стр. 20 - The simplicity of structure resembles, on the other hand, that found in the opossum and various Insectivora, Rodentia, and Quadrumana, and in the Proboscidia, most of which have the generalized type of feet. The structure indicates that the carnivorous genera named were plantigrade — a conclusion which is in conformity with the belief already expressed, that the mammalia of the Eocene exhibit much less marked ordinal distinction than do those of the Miocene or the recent periods. It is, indeed,...
Стр. 252 - Until such are discovered, there will be much ground for supposing that the camels of the old world were derived from American ancestors ; while the presence of the llamas in the existing South American fauna, indicates the absence there of the conditions which caused their extermination from North America.
