  Wanstead 
  in 
  an 
  almost 
  full-fed 
  condition, 
  and 
  feeding 
  on 
  dying 
  and 
  

   partially 
  withered 
  nettle, 
  this 
  possibly 
  may 
  account 
  for 
  their 
  

   darkened 
  shade, 
  and 
  also 
  to 
  their 
  being 
  somewhat 
  undersized.

  Mr.

  exhibited, 
  under

  a 
  series 
  of 
  slides 
  

   illustrating 
  the 
  life-history 
  of 
  the 
  Hydrozoa. 
  

  

  Mr. 
  W. 
  J. 
  Kaye 
  exhibited 
  a 
  very 
  fine 
  graduated 
  series 
  of 
  Helic'»uus 
  

   vielpoiiiene, 
  from 
  St. 
  Jean, 
  in 
  French 
  Guinea. 
  The 
  series 
  was 
  

   arranged 
  in 
  six 
  rows. 
  The 
  first 
  two 
  containing 
  specimens 
  with 
  a 
  

   black 
  hindwing 
  graduating 
  from 
  typical 
  melpn)iu'ne, 
  with 
  a 
  solid 
  red 
  

   discal 
  patch 
  of 
  the 
  forewing, 
  to 
  nuianipix', 
  a 
  form 
  with 
  the 
  yellow 
  

   group 
  of 
  spots 
  replacing 
  the 
  red, 
  only 
  traces 
  of 
  red 
  appearing 
  

   distally. 
  The 
  forms 
  shown 
  connecting 
  ineljiomene 
  to 
  iiielanippe 
  were 
  

   vielpomeniJeti, 
  lucinda, 
  liicia, 
  coliis, 
  and 
  inelpina. 
  Two 
  more 
  rows 
  

   contained 
  specimens 
  with 
  the 
  red 
  basal 
  streak 
  to 
  the 
  hindwing 
  only. 
  

   The 
  variation 
  covered 
  the 
  same 
  ground 
  as 
  the 
  first 
  series, 
  except 
  

   that 
  the 
  series 
  progressed 
  even, 
  further 
  by 
  showing 
  the 
  gradual 
  

   extinction 
  of 
  the 
  yellow 
  discal 
  spots 
  such 
  as 
  is 
  found 
  in 
  the 
  form 
  

   funehna. 
  Intermediates 
  between 
  diana 
  and 
  funebria 
  included 
  niarU, 
  

   dianides, 
  deinia, 
  negroida, 
  faiistina, 
  cubcle, 
  eiilalia. 
  

  

  The 
  last 
  two 
  rows 
  contained 
  again 
  the 
  same 
  variation, 
  but 
  with 
  

   the 
  addition 
  of 
  a 
  flame-streaked 
  hindwing. 
  Melpomene 
  is 
  thus 
  

   represented 
  by 
  tyche, 
  and 
  melanippe 
  with 
  the 
  black 
  hindwing, 
  is 
  

   represented 
  by 
  the 
  common 
  and 
  well 
  known 
  thelxiape. 
  Again, 
  in
