234 MR. G. E. HUNT ON MOSSES NEW TO BRITAIN, 



Wils,_, of which he considers it a form. D. circinatum 

 occurs on wet rocks^ as on Ben Voirloch, Loch Maree, &c., 

 and has strongly falcate or circinate leaves^ not decidu- 

 ous ; D. aristatmn in dry places^ and has the whole plant 

 slender, and the leaves spreading, silky, delicate, and very 

 deciduous. Under the microscope the two species are 

 quite identical : fruit not known. 



Dicranodontium sericeum, Sch., Soccoth Hill, Arrochar, 

 Mr. A. M'Kinlay. A barren form of Dicranum hetero- 

 mallum is very common on sandstone rocks, Cheshire, 

 which may be confounded with this species. Fruit not 

 known. 



Campylopus Schwarzii, Sch. (C auriculatus, Wils. MS.). 

 Exceedingly abundant in Scotland, and frequent in the 

 south of Ireland, on rocks — also on Snowdon, North Wales ; 

 liable to be overlooked as a state of C. flewuosus or C 

 longipilus. The structure of the leaf, however, more nearly 

 resembles that of C. fragilis ; but the leaves are auricled 

 at the base, have a nerve with only a single layer of large 

 hyaline cells, and are not interspersed with flagella. 



Campylopus compadus, Sch. (C. Schimperi, Wils.). Fre- 

 quent in the Scotch mountains, and also in the Hebrides 

 and Shetland Isles. Allied to C. Schwarzii, but at once 

 distinguished by its more slender habit and densely ces- 

 pitose, compact habit of growth. 



Campylopus alpinus, Sch. (C. intermedius, Wils. MS.). 

 On the moors near Llanberis, North Wales, and on rocks 

 at Stronachlacher, Loch Katrine, G. E. Hunt ; near Arro- 

 char, by Mr. M'Kinlay, with fruit very sparing. To be con- 

 founded with no species except Dicranodontium longirostre, 

 from which it differs in its leaf, with longer, narrower 

 cells in the lower part. The fruit is that of Campylopus. 



Campylopus Shawii, Wils. A most beautiful species (I 

 think, nearest to C.setifolius), having long, setaceous, almost 

 bristle-like leaves. Discovered by Mr. J. Shaw in the
