areathanhad been recognized by. Roemer, and:placed them im parallelism with the. 
Potsdam Sandstone and. Calciferous Sand Group of. Iowa, Wisconsin, and. 
Minnesota. In.his' present notice, the same author enters. into a more detailed. 
analysis of their mineral and other characters, and describes. several new Trilo- 
bites from. the lower or Potsdam Sandstone division. 
Gontributions-to Paleont»logy, By James Hall. (Fourteenth: Annual Report: 
of the Regents of the State Cabinet, Albany;. Appendix C,,and Continuation, 
July, August, and September, 1861), Professor. Hall, in these issues, continues. 
his descriptions-of various new fossils, comprising numerous brachiopods; cephalo- 
pods, trilobites, &c., chiefly from the Hudson River Group of Ohio and Tennessee,. 
and.from the Devonian Strata of New York. Qurrestricted space, at present, for- 
bids.an analysis of these forms ;. but.we may observe that in the first part of Ap- 
pendix.@, published in.July,,a description is given of a new Hwomphalus, named 
£.. Conradi.by, the author.. This species appears to be identical with the. Huom- 
phalus de Cewi.of Billings, described and. figured in the July number of. this 
Journal, Should this. apparent. identity prove true, we-think that Mr. Billings. 
may fairly. claim. the species, since that: number. of the Journal was published on 
the: 9th: of July, and. copies of Mr. Billings’ paper were previously transmitted. 
to:-him. Evyen.if the dates prove coincident, the description of the species in 
the:Journal must-be' looked upon as the more complete and satisfactory of. the 
two, as; it is. illustrated: by, figures. The Devonian trilobites. described. in. this 
Appendix by. Prof.,Hall, belong to the following, genera: Calymene, (1. species), 
Dalmania, (14 species), Phacops,, (3 species),, Proetus,, (15 species),, Lichasy, 
(2-species), Acidaspis, (fragmentary. examples), and: Beyrichia, (1-species). 
The. Goldiof Nova Scotiv, By A. C. Marsh,,A.B. (From the Am. Journ. of. 
Science and Arts, Nov. 1861.) This is an interesting account. of the newly- 
discovered gold districts of Tangier and- Lunenburg. The gold lies chiefly in 
quartz veins traversing disturbed strata of clay-slate. It is accompanied by 
mispickel and iron pyrites, the latter, according to Mr. Marsh, being more or less 
auriferous,* The author also abserved three crystallized specimens of gold from 
the Tangier locality, two of which: were: octahedrons, and the other a rhombic 
dodecahedron, with. bevelled edges. An analysis. of the Tangier. gold (sp. gr. 
18:95) gave Mr. Marsh: gold. 98°18 ;. silver. 7:76; copper 0°5; iron, a trace. A, 
sample. from Lunenburg, (sp. gr. 18737) consisted of: gold 92-04; silver 7-76.;, 
copper 0°11;, with also a. trace. of iron. These gold-containing. metamorphic, 
rocks: of Nova Scotia are referred. by Professor Dawson, (Acadian Geology: 
Supplement). to the base. of. the. Lower Silurian series. The gold appears. to; 
extend over a. wide area, since indications of it are said to. have been found. in. 
the sands‘ of Sable Island, at-a.distance of one hundred. miles or. more from. the; 
main land. 
The Canadian Naturalist and Geologist: (Vol. VI. No. 5.) Oct. 1861. This. 
Number. of the Naturalist is. an exceedingly. interesting one: In addition. to 
sundry: miscellaneous. notices, it- contains original papers by G. Barnston, E, 
Billings, H. G. Venner, Dr. Dawson, T. Sterry Hunt, and D. W. Beadle. The 
geological contributions..comprise an article on the occurrence of Graptolites in. 
* This we have verified in specimens obtained from Tangier, and kindly presented to use
