  New 
  Hampshire 
  particularly, 
  and 
  has 
  had 
  the 
  kindness 
  to 
  

   send 
  to 
  me 
  about 
  500 
  numbered 
  specimens. 
  Among 
  these 
  

   are 
  several 
  new 
  species 
  of 
  the 
  Acutifolium 
  group, 
  which 
  have 
  

   been 
  recentl}- 
  established 
  by 
  Prof. 
  Russow 
  or 
  by 
  myself, 
  re- 
  

   spectively, 
  or 
  by 
  us 
  jointly. 
  In 
  order 
  to 
  make 
  these 
  known 
  

   among 
  North 
  American 
  bryologists 
  I 
  shall 
  fully 
  describe 
  them 
  

   in 
  the 
  following 
  pages. 
  Furthermore, 
  in 
  Mr. 
  Faxon's 
  col- 
  

   lections 
  are 
  found 
  numerous 
  specimens 
  of 
  S. 
  affine

  whereby 
  I 
  am 
  enabled 
  to 
  make 
  perfectly 
  clear 
  the 
  po- 
  

   sition 
  of 
  this 
  species
