ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 481 



compiled by W. E. Nicholson for the Club from Roth's " Europiiische 

 Laubmoose," and other sources, a compact list of genera, species and 

 varieties on one folded sheet, intended for ready circulation by post. 



British Fossombronise.* — A. S. Home publishes some observations 

 on Fossombronia. Having collected specimens of this genus in Devon- 

 shire, Surrey and Durham, and rinding their identification to be uncer- 

 tain, he gives some statistics to show the great variability of the spore 

 markings. He describes also the situations in which the specimens 

 were growing and the plants with which they were associated ; also the 

 habit of the specimens during life. He demonstrates the presence of 

 amphigastria more or less fugitive and filamentous. 



Catharinea rhystophylla CM. in Britain. j — H. N. Dixon reports 

 the result of a critical examination of Catharinea rhystophylla and 

 G. angustata. The latter species is native; the former, a Chinese 

 species, has been reported from Ireland this year. G. rhystophylla was 

 distinguished by C. Midler from its congeners by its transversely rugu- 

 lose leaves. Dixon shows that there is no line of demarcation between 

 the G. rhystophylla of C. M tiller and the extreme form of G. angustata as 

 described by Limpricht. He therefore defines G. angustata var. rhys- 

 tophylla, and gives its distribution as far as known : China (Shensi) ; 

 Austria (Coglio) ; England (Kent) ; Ireland (Co. Down). 



Bryophytes of Somerset.} — W. Watson and W. Ingham publish a 

 list of bryophytes of Somersetshire, containing forty-three mosses and 

 twenty-nine hepatics, with localities representing new records for the 

 county. 



Bryophytes of Leicestershire^ — A. R. Horwood gives lists of all 

 new records of Cryptogamia for Leicestershire between 1886 and 1907, 

 including numerous bryophytes, and states the localities of the rare and 

 interesting species. He also tabulates those species which have dis- 

 appeared from the county and those which had been erroneously recorded 

 in time past. He devotes a chapter to the ecology and distribution of 

 cryptogamous plants in Leicestershire. 



Irish Mosses. — J. H. Davies || publishes a list of thirteen mosses of 

 Co. Down and eleven of Co. Louth, several of which are new records for 

 the respective counties. Notes on the more interesting species arc 

 a] i] tended. Ditrichum tmuifolium and Fissidens crassipes had only once 

 before been gathered in Ireland, and the latter species was without any 

 definite locality. Aulacomnium androgynum and Amblyodon ileal but us 

 are very uncommon in Ireland. Sterile specimens of a Philonotis — 

 apparently P. capillar is — were also found. 



The same author IT publishes a note on Barbula Hornschuchiana, 

 which though very rare in Ireland has been recently found in Co. Down
