Haypen’s TWELFTH ANNUAL REPORT OF THE U.S. GEOGRAPHI- 
CAL AND GEOLOGICAL SURVEY OF THE TERRITORIES OF WYOMING 
AND IpAHo.—These bulky and very richly illustrated volumes 
form the last of a series of twelve annual reports covering as — 
many years, from 1867 to 1879, and which is notable for contain- — 
ing a vast amount of valuable information concerning the geology — 
and natural resources of an immense area lying west of the Mis- 
sissippi valley and east of the Sierra Nevada range. It will be 
remembered that June 30, 1879, Congress passed a law discon- — 
tinuing this and the two other surveys then in existence, and 
establishing what is now known as the United States Geological 
Part 1 contains under the head of geology, seven illustrated 
articles by Dr. C. A. White, entitled Contributions to Inverte- 
brate Paleontology, 2-7, the first having appeared in the repor 
of the survey for 1877; with the report of Mr. O. St. Joga E 
geology of the Wind River district, and of Mr. Scudder on t 
Tertiary lake basin at Florissant, Col., the latter being a repni 
from the last volume of the Bulletin of the Survey. To se i 
to Dr. White's articles, which are illustrated by thirty-one ext” 
lent plates, among the large number of new forms descril bu 
most remarkable are two coral-like Cretaceous forms with Che. 
æozoic aspect, one referred with a good deal of doubt to ag 
tetes, though the tabulze are apparently absent, and it may %5
