also inhabiting Lower Canada. Of the turtle family, all the 

 Maine species have been detected in Canada East, with the excep- 

 tion of the mnd-turtle {Ozotheca odorata, Ag.) and the box-tur- 

 tle (Cistudo Virginea, Ag.). The newts and lizards have been very- 

 little explored : eleven species are known in Maine, and at present 

 but five in the neighborhood of Montreal. Dr. Dawson describes 

 some new plants from the Upper Devonian of the vicinity of the 

 Perry River, in addition to those already alluded to. These fossils 

 bear a striking resemblance to the plants of the coal-period, and most 

 of the genera, e. g. Stigmaria, Calamites, Dadoxylon, Cordaites, 

 Sphenopteris, and Hymenophyllites, range upwards into that for- 

 mation. The student of the fossils of the Quebec group and of 

 tbe Lower Silurian rocks generally in Canada, will find Prof. 

 Hitchcock's paper on the fossils of the Potsdam group well worthy 

 of perusal. Lastly, Mr. Billings contributes an important article 

 on Silurian and Devonian fossils from various parts of Maine. 

 He describes and illustrates several new species of shells (principally 

 brachiopods), also seven new trilobites. 



This journal, judging from the first numbers, bids fair to rank 

 hich among the scientific periodicals of the United States, and 

 clearly proves that the study of Natural History in Maine has not 

 been neglected. The illustrations are artistic, and the numbers on 

 the whole are well got up. J. F. w.

 London: Trubner & Co. Imp. 8vo. — This book, by a cor- 

 responding member of our Society, and one of the ablest living 

 Bryologists, is thus noticed by Prof. Gray in the November 

 number of Silliman's Journal : " We briefly announced this 

 work in the September number of this Journal, in terms of 

 unqualified admiration — which were intended to apply as well to 

 the scientific character of the volume as to the rare perfection of 

 the typography and the plates, One hundred and thirty species 

 are illustrated, a full plate (with one or two exceptions), and com- 

 monly two pages of letter-press, being devoted to each. The 

 detailed descriptions are in Latin, as also the explanation of the 

 plates ; the habitat and the general remarks are in English. The
