  This 
  genus, 
  which 
  appears 
  to 
  bear 
  a 
  close 
  relation 
  to 
  Edema, 
  Walk., 
  I 
  have 
  

   dedicated 
  to 
  my 
  friend, 
  Mr. 
  R. 
  H. 
  Stretch, 
  whose 
  exquisite 
  work 
  on 
  the 
  "Bom- 
  

   bycidae 
  of 
  North 
  America 
  " 
  is 
  an 
  honor 
  to 
  entomological 
  literature.

  Professor 
  Davidson 
  announced 
  that 
  he 
  had 
  received 
  permission 
  

   from 
  Commodore 
  Ammon 
  to 
  inform 
  the 
  Academy 
  of 
  the 
  important 
  

   results 
  of 
  the 
  soundings 
  made 
  by 
  Captain 
  George 
  E. 
  Belknap, 
  of 
  

   the 
  United 
  States 
  Steamer 
  Tuscarora 
  during 
  last 
  year, 
  with 
  

   reference 
  to 
  the 
  projected 
  laying 
  of 
  a 
  telegraphic 
  cable 
  from 
  this 
  

   coast 
  to 
  Japan. 
  This 
  he 
  proceeded 
  to 
  explain 
  with 
  the 
  aid 
  of 
  a 
  se- 
  

   ries 
  of 
  large 
  charts 
  and 
  profiles 
  prepared 
  for 
  the 
  occasion. 
  This 
  

   work 
  exhibited, 
  in 
  a 
  remarkable 
  manner, 
  the 
  depths 
  of 
  the 
  

   Pacific 
  Ocean, 
  which 
  had 
  no 
  parallel 
  in 
  the 
  plateaus 
  of 
  the
