ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 343 



Polytrichacese.* — W. Lorch gives a biological account of the Poly- 

 trichacese, dividing the work into three sections : (1) the gametophyte ; 

 (2) the sporophyte ; (3) the system of classification and plant geography. 

 He treats the matter in considerable detail. The Polytrichales are the 

 most highly organised mosses, and are not to be separated from the 

 Dawsoniaceee. 



Orthothecium strictum or 0. rubellum.t — I. Hagen proves by a 

 piece of careful reasoning that the binomial Orthothecium strictum has 

 precedence over 0. ruMlum, since (as he shows) Holmgrenia stricta 

 Lorentz must have been published at least a few days before Stereodon 

 riibellus Mitt. 



Notes on Fontinalis.J — J. Cardot protests against a recent statement 

 by 1ST. C. Kindberg that Fontinalis maritima is allied to F. mollis and 

 not to F. neomexicana. Cardot has examined the original specimens of 

 Carl Midler, and is able to demonstrate that F. maritima belongs to a 

 totally different section of the genus from that to which F. mollis 

 belongs, and is extremely nearly allied to F. neomexicana, being perhaps 

 only a maritime form of it, and found only on the western coast of 

 North America. 



Notes on Drepanocladus.§ — F. Renauld publishes a second article 

 on the species of Drepanocladus (Harpidium), based upon specimens 

 contained in the Paris Museum, in F. Camus's herbarium, etc. As even 

 the best descriptions without drawings are insufficient, he is preparing 

 an album of plates showing the principal characters of all the forms 

 described ; and this album will be added to his herbarium of Harpidia 

 which is already placed in the Paris Museum. In the present article he 

 treats of the European and North American forms of Drepanocladus 

 aduncus ; ten varieties or forms in group typicum, and two in group 

 Kneiffii. 



Norwegian Mosses. || — H. Winter publishes a general report upon 

 his six bryological journeys in Norway, together with notes on the rarer 

 species collected by him in Germany, Austria, and Switzerland. After 

 giving a geographical sketch of the districts visited, he furnishes a sys- 

 tematic account of the mosses, consisting largely of critical notes upon 

 the various and numerous species. Interspersed are a few new species. 



I. Hagen 1f publishes another part of his preliminary studies of the 

 Norwegian moss-flora, in which he treats of the Splachnacea?, Oedipo- 

 diacete, Leucodontacea?, Ceratodontaceas, Encalyptaceee, Seligeracere. 

 The text is mainly in Norwegian, but the parts of general interest are 

 in French. 



Mosses of Hamburg.** — J. Schmidt publishes some new data about 

 the Hamburg flora, bringing it up to the level of modern efficiency.
