  by 
  chains 
  from 
  the 
  beams 
  of 
  the 
  roof 
  in 
  the 
  back 
  wing 
  of 
  Geolog- 
  

   ical 
  Hall, 
  was 
  taken 
  down, 
  entirely 
  taken 
  apart 
  and 
  thoroughly 
  

   cleaned 
  by 
  Mr 
  Mirguet, 
  and 
  the 
  skeletons 
  of 
  the 
  other 
  large 
  

   mammals 
  were 
  similarly 
  treated 
  after 
  disarticulating 
  them 
  as 
  

   much 
  as 
  necessary. 
  

  

  Although 
  the 
  Museum 
  has 
  not 
  been 
  officially 
  open 
  to 
  the 
  pub- 
  

   lic, 
  people 
  desiring 
  to 
  see 
  the 
  collections 
  were 
  not 
  excluded 
  from 
  

   the 
  exhibition 
  rooms 
  until 
  the 
  dismantling 
  of 
  the 
  exhibits 
  had 
  

   progressed 
  so 
  far 
  that 
  too 
  little 
  remained 
  to 
  attract 
  visitors, 
  and 
  

   the 
  spaces 
  in 
  the 
  exhibition 
  rooms 
  were 
  required 
  for 
  the 
  storage 
  

   of 
  the 
  packed 
  material. 
  

  

  MONOGRAPH 
  OF 
  THE 
  NEW 
  YORK 
  MOLLUSCA 
  

  

  Dr 
  H. 
  A. 
  Pilsbry's 
  work 
  upon 
  the 
  monograph 
  of 
  the 
  New 
  York 
  

   Mollusca 
  during 
  the 
  year 
  has 
  been 
  directed 
  chiefly 
  to 
  determin- 
  

   ing 
  the 
  generic 
  characters 
  of 
  numerous 
  forms 
  hitherto 
  inade- 
  

   quately 
  known. 
  To 
  this 
  end, 
  considerable 
  collecting 
  has 
  been 
  

   done 
  in 
  the 
  Hudson 
  valley, 
  Onondaga 
  county 
  and 
  elsewhere 
  to 
  

   procure 
  fresh, 
  living 
  material 
  for 
  description. 
  Some 
  forty-five 
  

   figures 
  of 
  living 
  mollusks 
  have 
  been 
  drawn 
  by 
  the 
  author, 
  includ- 
  

   ing, 
  among 
  others, 
  representatives 
  of 
  the 
  following 
  genera 
  : 
  

  

  Lyogyras 
  

  

  Planorbis 
  

  

  Zonitoides 
  

  

  Amnicola 
  

  

  Segmentina 
  

  

  Gastrodonta 
  

  

  Pomatiopsis 
  

  

  Physa 
  

  

  Helicodiscus 
  

  

  Valvata 
  

  

  Pupilla 
  

  

  Vallonia 
  

  

  Goniobasis 
  

  

  Bifidaria 
  

  

  Arion 
  

  

  Lioplax 
  

  

  Vitrea 
  

  

  etc., 
  etc. 
  

  

  Lymnaea 
  

  

  

  

  The 
  external 
  anatomy 
  of 
  part 
  of 
  these 
  genera 
  has 
  hitherto 
  been 
  

   known 
  in 
  American 
  works 
  by 
  figures 
  of 
  foreign 
  species 
  copied 
  

   from 
  European 
  works, 
  or 
  by 
  very 
  crude 
  figures 
  and 
  descriptions. 
  

   The 
  external 
  soft 
  parts 
  of 
  part 
  of 
  them 
  have 
  not 
  before 
  been 
  fig- 
  

   ured 
  or 
  described. 
  It 
  is 
  believed 
  that 
  the 
  new 
  facts 
  brought 
  out 
  

   in 
  the 
  course 
  of 
  this 
  work 
  on 
  American 
  species 
  are 
  ample 
  com- 
  

   pensation 
  for 
  the 
  time 
  and 
  labor 
  spent 
  thereon. 
  Further 
  work 
  

   has 
  been 
  done 
  on 
  the 
  descriptive 
  part, 
  and 
  a 
  large 
  number 
  of 
  

   illustrations 
  made, 
  figuring 
  all 
  of 
  the 
  species 
  which 
  have 
  been 
  

   worked 
  up. 
  The 
  completion 
  of 
  the 
  monograph 
  is 
  expected 
  next 
  

   year 
  (1913).
