in papers published by Bescherelle, Corbiere, Theriot, Camus, and 

 amount to ninety-nine mosses and six hepatics. The additions bring 

 tlic totals up 137 mosses and forty-four hepatics. The new specimens 

 were gathered mostly in the neighbourhood of Ain-Draham (Khrou- 

 mirie). One species is new. 



In a subsequent paper* they give a complete enumeration of the 

 moss-flora, indicating the distribution, attitudes, moss-associations, etc. ; 

 and they raise the totals to 152 mosses and forty-eight hepatics. 



HepaticaB of New Caledonia.f — E. G. Paris publishes a list of 250 

 hepaticae collected in New Caledonia by Le Rat, and determined by 

 F. Stephani. Some 100 of these arc new, but their descriptions are 

 not likely to be published before the appearance of the Supplement of 

 Stephani's Species Hepaticarum. 



Polytrichaceae of North America. + - -T. C. Frye publishes an 

 illustrated account of the Polytrichaceae of western North America. 

 Starting with a synoptical key of the world's genera of Polytrichaceae, 

 he adds a key to the genera native to western North America, and then 

 proceeds to give a systematic treatment of each genus, supplying de- 

 scriptions and figures of the species. The genera concerned are ( 'atharinea, 

 Oligotrichum, Psilopilum, Bartramiopsis, Polytrkhadelphus, Pogonatum, 

 Polgtrkh urn . 



Mexican Mosses. §— J. Cardot publishes the eighth instalment of 

 his preliminary diagnoses of Mexican mosses, in which are described a 

 new genus, Anomobryopsis, fourteen new species, and a new variety. 

 Critical notes are appended. The specimens were collected by Pringle, 

 Purpus, Barnes and Land, and others. 



In his ninth instalment || he treats of thirty-four species and 

 varieties. 



Splachnobryum in Greenhouses.^" — E. G. Britton gives an account 

 of a Splachnobryum found in greenhouses near Philadelphia. She 

 states it to be identical with S. delicatulum Broth, described by H. N. 

 Dixon in 1907, and found in a Yorkshire hot-house. Both plants have 

 the preperistome described by Dixon. A similar preperistome or bind- 

 ing membrane is shown by Fleischer to be present in S. Geheebii ; 

 and E. G. Britton finds it also in 8. Wrightii, S. JJariei, S. Wullschlse- 

 gelii and S. B&rnouillii ; and traces of it in S.flaccidum and S. Boivini. 



Fissidens tequendamensis Mitten.** — H. N. Dixon supplements 

 some remarks which he published about Fissidens tequendamensis ft 

 recently when describing the new Irish species, F. exsul. At his request 

 E. G. Britton examined the type of F. tequendamensis in Mitten's her- 

 barium and found it to be identical with F. Lindigii Hampe, both 

 plants having come from the same type-locality, the Falls of Tequen-
