that some species, when cultivated in vessels in a laboratory, are liable 

 to assume a very different habit, as the result of being confined in a 

 closed damp atmosphere. Herbarium specimens are often old and worn. 

 Yet in Orthotrichum and Grimmia it is essential that certain fugacious 

 structures, such as peristome-cilia, annulus, calyptra, should be present 

 and in the best condition of maturity. 



A. J. Grout * publishes a correction, in which he changes the name 

 Arribly&tegium Holzingeri to A. americanam. 



A. W. Evans f begins a series of notes on North American hepaticae, 

 excluding the New England species alread}' discussed in Rhodora. He 

 treats of such species as are interesting by reason of their rarity, their 

 critical character, or their distribution. 



A. Lorenz % discusses some Lophozias of the Ventricosa group, viz., 

 L. longidens, L. longiflora, and L. eonfertifolia, giving figures of their 

 habit and structure, and notes on their distribution and systematic 

 characters. 



N. C. Kindberg§ publishes some bryological notes mostly relating 

 to North American mosses, twenty-three collected in the United States 

 by Nelson, and five in Canada by Macoun and Brinkman. A Rhabdo- 

 iveisia, new to Germany, is recorded for Eisenach ; and a new species, 

 Trichostomum alpinum, gathered in Colorado by Nelson, is described. 



Mexican Mosses. || — -J. Cardot continues the publication of his 

 preliminary diagnoses of Mexican mosses, principally collected by 

 Pringle. In the present article are described twenty-five species, six 

 varieties, and the new genus Platygyriella, belonging to the family 

 Entodonteacese, and differing from Platygyrium in the structure of its 

 outer peristome. 



Moss-flora of the Isle of Pines. % — E. G. Paris gives a preliminary 



list of the moss-flora of the He des Pins of the New Caledonia group. 

 Madame Le Rat recently spent a month there collecting specimens, and 

 with her husband intends to explore the much bigger neighbouring 

 island with equal care. Paris gives an account of the physical geography 

 of the islands, and enumerates in his list seventy mosses, twenty-one of 

 which are new and will be published with descriptions in a forthcoming 

 memoir by V. F. Brotherus. Eight out of the ten species which were 

 recorded in the Flora Vitiensis as having been gathered in the Isle of 

 Pines by Strange and Milne, are viewed with the strongest suspicion by 

 Paris. Further, a list of twenty-one hepaticae is furnished by Stephani, 

 and nine of these are new to science. 



Chinese Muscineae.** — E. G. Paris publishes his eleventh article on 

 the MuscineSB of Eastern Asia, and treats of further collections made by 

 the French missionaries Courtois and Henry in the Chinese provinces of 

 Kan Sou and Tche Kiang. He enumerates thirteen mosses, six of which 

 are described as new to science, and two hepatics.
