176 Parallelism of the Paleozoic Deposits 
found abundantly by Dr. Susie of Penn Yan, and named by 
Gay as distinct, C. Sartwelliana. But Dr. Gray ascertained it to 
belong to C. oligocar a, of which it seems to be a manifest va- 
riety and to deserve the ‘following designation. 
C. oligocarpa, Schk. ; var. Sartwelliana, D.;—C. Sartwelliana, 
Gay. 
Fruit subovate, oblong, roundish triquetrous, tapering above or 
short-conic rostrate, about equalling or surpassing the short, ovate, 
obtuse pre! —— awned scale. 
The fruit of C. Hitchcockiana is tapering at both ends; this 
is i sic, and is far less obovate and more tapering at the apex 
than that of CU. oligocarpa.

Art. XX.—On the Parallelism of the Paleozoic Deposits of 
North America, with those of Europe; followed by a Tuble 
of the Species of Fossils common to the two Continents, with 
ieee of the MT in which in occur, one terminated 
critical excamination of each of these species; by Ep.

Geol. Soc. of France, 2d ser., vol. iv,* for this Journal ; by Mr. 
James Haut, New York State Geologist. 
“ Arrer having studied, during many years, in Russia and in 
Sweden the distribution af the fossils of the Palaeozoic strata, the 
principal object of my short visit into North America, was to ascer- 
tain if the stratigraphical distribution of animals, is the same 
there as in Euro It was therefore necessary to become famil- 
iar first with the ‘geology of this immense country, by collect- 
ing from each bed the different fossils, or at least the princi- 
pal ones, in order to distinguish, Ist, the species proper to a 
ica; 2d, the species identical with those of Europe. The first 
point will be left for a subsequent work, in which we shall oc- 
cupy ourselves a with the geology of the United States; the 
second, will form the subject of the following remarks, whic 
I shall a Bata to restrict within limits appropriate to the
