Census of Irish Mosses.*— II. W. Lett publishes a census report 

 on the mosses of Ireland. He records under each species the provinces 

 iu which it has been found, adding the actual locality, date, collector's 

 name, and a reference to the publication or herbarium upon which the 

 record is founded. The provinces adopted are those defined by J. LI. 

 Praeger. The census is preceded by a report on the progress of bryology 

 in Ireland, in which short biographical notices of the collectors of, and 

 writers on, Irish mosses are given. A bibliography is supplied, and a 

 list of the 118 species and varieties added to the flora since the publica- 

 tion of David Moore's Synopsis (1872). 



Mosses of Jamtland.f— H. Persson has examined bryologically the 

 alpine regions of south-west Jamtland and north-west Harjedalen, and 

 publishes here a list of his collections. The total number recorded is 

 243 species, of which 162 are acrocarpous and 81 are pleurocarpous. 

 Amlrecca Thedenii, Bryum comense, and B. jemtlandicum are new to 

 Sweden. The last species is new to science, and is allied to B. micro- 

 stegium, B. misandrum and B. sarekense. The points of difference are 

 set forth. Three new varieties are described, and special attention is paid 

 to Andrma Thedenii. The author was fortunate enough to find the 

 hitherto unknown fruit of Astrophyllum hymmophylloides. The struc- 

 ture of the peristome shows that the species belongs to Astrophyllum 

 ( = Mnium), and not to Ginclidium, as has been suggested. The author 

 criticizes the view that A. hijmenophylloictes is identical with G. hymeno- 

 phyllum, but agrees to place the latter species in the genus Astrophyllum. 

 The paper includes tables showing the distribution of the larger genera 

 in different regions, the fertility of the species, their origin, etc. 



Hepaticse from Hungary and Croatia4 — V. Schiffner writes on 

 the Hepaticse of Hungary and the Hohe Tatra, and records several 

 species new to the regions. A species which he had previously deter- 

 mined as Marsupella emarginata Dum., from the neighbourhood of the 

 Griiner See in the Tatra, should rather be placed in M. Pearsonii. The 

 leaf-margins are very strongly incurved. The larger forms resemble 

 more or less M. aquatica. 



North American Hepaticse.§— A. W. Evans publishes further notes 

 on New England HepaticEe. In Article No. 11 he treats of Olevea 

 hyalina, Neesiella rupestris, Lophozia grandiretis, L. quinquedentata, 

 Plagiochila Austini (formerly regarded as identical with the European 

 P. spmulosa Dum.), Gephalozia media, Diplophyllum gymnostomophilum, 

 and discusses their structural characteristics and their affinities iu some 

 detail.
