The variety is not known to have been found elsewhere than in Tyrol 

 and the Pyrenees. H. W. Lett * announces the discovery in Ireland of 

 a moss, Gatharinea rhystophyUa C. Muell., hitherto known only as a 

 native of North China. It was growing on the mud-cap of a stone wall 

 in Co. Down, with Geratodon purpureus and Stereodon cupressiforme. 

 H. N. Dixon f records the finding by J. Hunter, of Gampylopus 

 brevipilus in fruit in North Donegal during July, 1907, and he describes 

 the calyptra, operculum, etc. The species has only once previously been 

 recorded in fruit •> it was so found by E. Jorgensen on the Island of 

 Stord, on the west coast of Norway. A. S. Home J records the 

 discovery of the rare hepatic Haplomitrium Hookeri, near Budleigh 

 Salterton, in Devonshire, in August and December, 1906. But since 

 then he has been unable to find any more specimens in the same spot. 

 D. A. Jones § records the first finding of Riccia Grozalsii in Britain, 

 he and S. J. Owen bavins; gathered it at Barmouth, associated with 

 R. glaaca, R. sorocarpa, R. nigreUa, and R. Lescuriana on a mud-capped 

 wall in September of last year. The plant was determined by S. M. 

 Maevicar and M. Crozals. The original type of the species was found 

 near Montpellier, in the south of France, and was described by E. Levier 

 in 1902. A translation of Levier's diagnosis is given in the present 

 paper, and some critical notes are added showing how the species differs 

 from R. ciliata, R. Michelii var. ciJiaris (= R. tumida), R. Lescuriana 

 (= R. glaucescens). The species has been recorded from other places 

 in the south of France, the north of Italy, Tyrol, and now from the 

 Welsh counties Merioneth and Carnarvon. W. E. Evans || records the 

 discovery of PhyscomitreUa patens in reservoirs near Edinburgh, during 

 a long period of drought. The plant was found in abundance associated 

 with male plants of Funaria hygrometrica, and with Riccia crystallina. 

 It is not known to have been gathered in Scotland previously. 



North American Bryophyta.1T — A. Lorenz publishes some notes on 

 Cepltaloziella myriantha and G. divaricata, as found in New England. 

 The two species have been confused ; but C. myriantha is distinguished 

 by having a paroicous inflorescence. She gives a history of the species, 

 and shows how Schiffner came to the conclusion that the northern 

 G. myriantha and the southern C. Jachii are one and the same species. 

 She describes the habitat (dry rock), living appearance and morphology 

 of C. myriantha. As to the other species, G. divaricata, she refers to the 

 different opinions of European authors, and shows that Warnstorf split 

 the species into two— 6'. divaricata and G byssacea; and she cites 

 Warnstorf 's descriptions of those two species. Stephani and Massalongo 

 agree with Warnstorf ; but Schiffner holds different views. C. divaricata 

 grows in damper, more shaded places, than does C. myriantha. E. G-. 

 Britton** publishes some notes upon the nomenclature of North American 

 mosses based upon Brotherus' last contributions to the section of mosses 

 in Engler's Pflanzenfamilien. J. D. Lowe ft gives a list of fifteen hepatics 

 and forty-nine lichens collected in Nova Scotia at the narrowest part of
