dz from the Cretaceous rocks of Texas.” And the third is “On 
the nautiloid genus Enclimatoceras Hyatt, and a description of 
the type species.” In Vol. vi of the Proc. of the U. S. National 
Museum he has an article “On the Macrocheilus of Phillips, 
Plectostylus of Conrad, and Soleniscus of Meek and Worthen. 
In Science, Vol. 111, he has a note on the “ Enemies and parasites 
of the oyster, past and present.” In the 13th annual report of 
the Indiana Department of Geol. and Nat. Hist., the same author 
has “ The fossils of the Indiana rocks, No. 3.” In this work he 
gives excellent illustrated descriptions of the characteristic inver- 
tebrate animal remains of the Carboniferous period. 
J. F. Whiteaves, in the Geol. and Nat. Hist. Surv. of Canada, 
has Part 111 of his Mesozoic fossils, “On the fossils of the coal- 
bearing deposits of the Queen Charlotte islands collected by Dr. 
G. M. Dawson in 1878. The author is driven by his conclusions 
to assert that the Jurassic of the Black hills and Rocky mountains 
is Cretaceous. This assertion is far from being justified by the 
facts which the author adduces for its support. He has also 
Part 1 of Vol. 11 of “ Paleozoic fossils.” In the Trans. Royal 
Soc. Canada, he has an article on the “Lower Cretaceous 
rocks of British Columbia.” In this article he holds thatthe 
presence of an abundance of Ancellz is a sure proof of the Neo- 
comian age of the rocks in which they occur. In the same pub- 
lication he has also an article “On some supposed Annelid tracts 
from the Gaspé sandstones.” 
R. P. Whitfield, in the Bull. Amer. Museum Nat. Hist. Vol. 1, 
No. 5, has a “ Notice of some new species of primordial fossils in 
the collections of the museum, and corrections of previously 
described species.” He thinks that the difference in faunas be- 
tween the different Cambrian areas is more the result of the con- 
ditions upon which life depended than a difference in time. 
H. S. Williams, in the Bull. U. S. Geol. Surv., Vol. No. 3, has 
an article “ On the fossil faunas of the Upper Devonian along the 
meridian 76° 30’ from Tompkins county, New York, to Bradford 
county, Pennsylvania.” The paper is the first of a series. In 
Science, Vol. 111, he has an article on “ The Spirifers of the Upper 
Devonian.” 
H. Woodward, in the Geological Magazine for February and 
for April, has two articles, one is “On the structure of Trilo- 
bites.” This is a reproduction of the author’s views on the ap-
