“A comparison of the Eocene Mollusca of South-eastern United 
States and Western Europe in relation to the determination of 
identical Forms,” and “ Stratigraphical evidence afforded by the 
Tertiary Fossils of the Peninsula of Maryland.” The first of 
these papers is illustrated by a plate of figures; the other two 
embrace some important philosophical discussions. Mr. Heil- 
prin has begun the preparation of a monograph of the Tertiary 
Fossils of Eastern North America. 
George Jennings Hinde, Esq., F. G. S. of Surrey, England, 
published in the Quarterly Journal of the Geological Society for 
August, 1879, pages 352-369, an important memoir “ On Cono- 
donts from the Chazy and Cincinnati group of the Cambro- 
silurian, and from the Hamilton and Genesee Slate divisions of 
the Devonian in Canada and the United States.” Palzontologists 
have been divided in opinion as to what class of animals these 
interesting remains belong to, and Mr. Hinde’s important memoir 
still leaves us in doubt upon this point, although he has much 
enlarged our knowledge concerning the objects themselves. 
In 1878 Mr. U. P. James began, at Cincinnati, the publication 
of The Paleontologist, for which he is thus far the only writer. 
Four numbers have been printed, aggregating thirty-two pages 
octavo, two numbers of which have appeared in 1879. In these 
two numbers Mr. James describes twenty-one new forms of 
Lower Silurian fossils, and proposes two new fucoid genera, 
Saccophycus and Lockeia. 
Mr. Victor W. Lyon described three new forms of Ca/ceola 
from the Upper Silurian rocks of Kentucky, in the Proceedings 
of the Academy of Natural Sciences at Philadelphia for 1879, 
pages 43-46. 
Mr. S. A. Miller has, during the past year, published in pam- 
phlet form, of thirty-five pages, a revision of his “Catalogue of 
Fossils found in the Hudson River, Utica Slate and Trenton 
groups, as exposed in the south-east part of Indiana, south-west 
part of Ohio and northern part of Kentucky,” which originally 
appeared in the Tenth Annual Report of the Geological Survey — 
of Indiana. In the April number of the Journal of the Cincin- 
nati Society of Natural History, pages 31-42, he has “ Remarks 
upon the Kaskaskia group, and descriptions of new species of 
Fossils from Pulaska county, Kentucky;” the new forms being 
illustrated, with others, upon the two plates which that number
