as a generic term, extending it to the Andes and to the eastern range, 
the Rocky Mountains. Other geologists have sought to make the Rocky 
Mountains the generic name, including in that range all the rest, and 
making the Sierra Nevada a branch.: He was now inclined to think 
there is difference enough in the two ranges to regard them as separate, 
and perhaps almost independent ranges. One object of his visit was to 
examine the Yosemite Valley, and study the phenomena of its formation, 
and this he had been enabled to do. At some time he hoped to be in a 
position to study the geology of the coast carefully. 
Professor Davidson added some remarks on the climatology of the 
coast with reference to ocean currents, and thereafter the Academy ad- 
journed. 
— The Princeton College student-expedition to the Rocky Mountains 
appeared to meet with good success. It started June 21st, and returned 
early in August, having accomplished a good deal in exploring the bot- 
any, zodlogy, paleontology, mineralogy, and topography of Colorado and 
the region about Fort Bridger in Wyoming. Nearly a thousand species 
of plants were collected. Of zoélogical specimens there were secured 
the heads of mountain sheep, elk, deer, antelope, bear, beaver, mountain 
lion, lynx, wild-cat, badger, etc., with complete skeletons of many ani- 
mals of lesser size. A goodly collection of fossils was obtained in Col- 
orado and in the Uintah Mountains. 
— We have received Monographs of North American Rodentia, 
by Elliott’ Coues and Joel Araph Allen. Published as one of the quarto 
series of the United States Geological Survey of the Territories, F. V. 
Hayden in charge. Washington, 1877. It contains eleven monographs, 
five by Dr. Coues and six by Mr. Allen, with appendix; A Synoptical 
List of the Fossil Rodentia of North America, by J. A. Allen, and Ap- 
pendix B.; Material for a Bibliography of North American Mammals, 
by Theodore Gill and Elliott Coues. The volume is carefully indexed, 
comprises 1091 pages, and contains fine plates illustrative of the skulls 
of the Muride. It may be truly said to be a monumental work upon a 
single order of mammals. 
— One of the most valuable and, useful works on zodlogy ever pub- 
lished and which is still passing through the press, is Bronn’s Klassen 
und Ordnungen des Thier-reichs. Of the fifth volume, Arthropoda, 
Lieferung 24 has been the last published. ‘The volume so far as it goes 
is accompanied by thirty-nine plates, and the text has been prepared by 
Professor Gerstaecker, the well known entomologist. 
— A second edition of the Index Geological Map of Newfoundland, 
on the scale of twenty-five miles to an inch, has been published by Mr. 
Murray, whose report for 1876 has been issued. i 
— The Norwegian Expedition to the North Sea has met with fair 
success, especially in mapping the sea bottom off the coast of Norway, 
and ascertaining the limits of the extended barrier which keeps back the 
cold water coming from the depths of the Polar Sea.
