and figures are restored according to the idea that the author had 
of the way in which they ought to be. 
This year we have the first volume of the Transactions of the 
Royal Society of Canada. The committe on publication cannot 
be too severely criticised for having printed a large quarto of 
about 700 pages, containing many interesting papers, without any 
index, and for using five different systems of pagination, as well 
as varying the system of headings for each page. 
H. M. Ami has notes on Triarthus spinosus in the Trans. 
Ottawa Field Nat. Club. 
Chas. E. Beecher, in Report. P.P.P. 2d Geol. Surv. Penna., has 
an excellent article on the “ Ceratiocaride an the Chemung 
and Waverley groups at Warren, Pennsylvania. 
W. B. Billings has “ Notes on, and description of some fossils 
from the Trenton limestone,” in the Trans. Ottawa Field Nat. 
Club. 
E. J. Chapman publishes, in the Trans. Roy. Soc. Canada, a 
“ Classification of Crinoids” based on the presence or absence of 
a canaliculated structure in the calyx and arm plates. , 
E. W. Claypole has an article “On the occurrence of the 
genus Dalmanites in the Lower Carboniferous rocks of Ohio,” in 
the Geological Magazine for July; also a Preliminary note on 
some fossil Fishes recently discovered in the Silurian rocks of 
North America, in the AMERICAN NATURALIST for December. 
William B. Dwight, in the Amer. Fourn. of Science and Arts 
for April, has his fourth article on “ Recent explorations in the 
Wappinger Valley limestone of Dutchess county, New York, 
No. 4, Descriptions of Calciferous ? fossils.” 
Aug. F. Foerste, in the American NATURALIST for January, 
has a note on “ The power of motion in Crinoid stems.” 
W. M. Fontaine, in the monographs of the U. S. Geol. Survey, 
has published his “ Contributions to the knowledge of the older 
Mesozoic flora of Virginia.” This work is divided into three parts ; 
in the first the author gives a brief description of the geology of _ 
the Virginia Mesozoic areas. In the second he describes the 
flora and compares it with plants from the Triassic, Jurassic and 
Rheetic of other regions. In the third he republishes Emmons’ 
figures of the Mesozoic flora of N. Carolina, compares it with the 
Virginia flora, considers both floras as of the same age, and that 
age as not older than the rheetic.
