XXXVI ADDENDA. 



p. 194. Under Bryum erythrocarpiim 



Mr. Wilson considers var. 7. murorum, Schimp., which is peculiar to 

 mortared walls, and occurs at Bristol, and not unfrequently in North Wales, as 

 a distinct species, under the name of B. murale, Wils. 



p. 197. Under Bryum pseudotriquetrum, insert 



var. S. cavifolilim, Schimp. (Bryum neodamense, Itzigsohn), has been 

 found near Southport by Mr. Wilson. 



p. 198. After Bryum pallens, insert 



23*. B. Duvalii, Voit; tufted, very soft, bright purple ; stems tall; leaves 

 distant, spreading, very decurrent, broadly ovato-lanceolate, quite entire ; nerve 

 vanishing below the tip ; sporangium equal, constricted below the mouth when 

 dry. 



In bogs. Found by Mr. Wilson, but I do not know the exact locality. 



p. 254. Under T. oblvngifolia, insert 



Tortula oblongifolia has lately been found in Sussex? I am mistaken in say- 

 ing it is not taken up by Schimper. A description will be found compiled from 

 the ' Bryologia Britannica,' at p. 185 of the Synopsis. It is doubtful whether 

 it really differs from T. Vdhliana. 



p. 286. Under Arctoa fulvella, insert 



(Plate 23, fig. 10.)
