﻿14 
  TWENTY-NINTH 
  EEPORT 
  ON 
  THE 
  STATE 
  MUSEUM. 
  

  

  portion 
  of 
  which 
  had 
  been 
  incorporated 
  with 
  the 
  Museum 
  collections. 
  

   Dr. 
  Lewis' 
  familiarity 
  with 
  most 
  of 
  the 
  species 
  enabled 
  him 
  to 
  pass 
  

   this 
  material 
  under 
  his 
  critical 
  review 
  during 
  a 
  few 
  weeks' 
  engage- 
  

   ment 
  at 
  the 
  Museum, 
  and 
  it 
  is 
  due 
  to 
  him 
  to 
  say 
  that 
  the 
  work, 
  

   requiring 
  much 
  experience 
  and 
  discrimination, 
  was 
  satisfactorily 
  

   accomplished. 
  

  

  The 
  collections 
  consist 
  largely 
  of 
  Unionidse. 
  Of 
  these, 
  each 
  

   example 
  has 
  had 
  inscribed 
  on 
  the 
  inner 
  side 
  of 
  one 
  valve 
  the 
  serial 
  

   number 
  or 
  order 
  given 
  in 
  the 
  " 
  Synopsis 
  of 
  the 
  Family 
  Unionidse 
  ;" 
  * 
  

   thereby 
  insuring 
  the 
  proper 
  reference, 
  should 
  the 
  specimen 
  become 
  

   separated 
  from 
  its 
  label. 
  These 
  specimens 
  have 
  been 
  arranged 
  in 
  

   three 
  collections 
  (catalogues 
  of 
  which 
  are 
  herewith 
  presented), 
  viz. 
  : 
  

  

  1. 
  Unionidse 
  of 
  the 
  State 
  of 
  New 
  York. 
  All 
  the 
  species 
  credited 
  

   to 
  the 
  State, 
  with 
  the 
  single 
  exception 
  of 
  Unio 
  Boydianus 
  Lea, 
  

   fifty-two 
  in 
  number, 
  are 
  represented 
  in 
  this 
  collection 
  by

  varieties, 
  represented 
  in 
  1,042 
  examples. 
  A 
  few 
  only 
  of 
  these 
  

   are 
  exhibited 
  under 
  glass, 
  where 
  the 
  species 
  is 
  shown 
  in 
  specimens 
  

   from 
  different 
  localities 
  ; 
  otherwise 
  the 
  series, 
  for 
  want 
  of 
  room, 
  is 
  

   arranged 
  in 
  drawers 
  43 
  to 
  51 
  of 
  the 
  Gould 
  cabinets. 
  Access 
  to 
  these 
  

   may 
  at 
  any 
  time 
  be 
  obtained 
  by 
  the 
  student 
  through 
  application 
  at

  382 
  distinct

  with 
  the 
  

   principal 
  collections 
  in 
  the

  try 
  .f
