The mofs here reprefented is undoubtedly the Bryum figured by Dillenius, in his forty-fifth plate, forty-eighth 

 figure. Neither Linnaeus nor Mr. Hudson make mention of it. We are convinced, however, from repeated 

 obfervations, that it is a fpecies perfectly diftmcl:. It approaches very near to the Bryum imberbe and unguiculatum. 

 From the former it differs in having the Antherae or Capfules terminated by long twifted ciliae, and in having the 

 peduncles always proceeding from the bafe of the furculus : this laft character alfo ftrikingly diftinguifhes it from 

 the unguiculatum. 



It is not unfrequent about London, efpecially in the environs of Charlton, on walls, and barren hilly ground, 

 with the Bryum purpureum and cafipititium, and produces its fructifications in December, January, and February.
