  rather 
  feeble 
  and 
  a 
  second 
  pair 
  of 
  very 
  robust 
  maxillipeds, 
  moved 
  

   by 
  very 
  powerful 
  striated 
  muscles. 
  The 
  terminal 
  portion 
  of 
  the 
  

   body 
  is 
  obtuse 
  and 
  terminated 
  by 
  two 
  lateral 
  lobes, 
  containing 
  the 
  

   sacs 
  for 
  the 
  spermatophora. 
  These 
  organs, 
  which 
  are 
  regularly 
  

   spherical, 
  are 
  united 
  with 
  the 
  testes 
  by 
  fine 
  deferent 
  ducts. 
  

  

  In 
  the 
  form 
  of 
  the 
  female 
  and 
  in 
  the 
  multiplicity 
  of 
  the 
  ovigerous 
  

   sacs, 
  which 
  are 
  so 
  rare 
  among 
  the 
  Copepoda, 
  Aspidcecia 
  closely 
  

   approaches 
  Choniostoma 
  mirabih 
  recently 
  discovered 
  by 
  H. 
  J. 
  Han- 
  

   sen 
  beneath 
  the 
  branchial 
  integuments 
  of 
  Hippotyte 
  polaris 
  and 
  

   Oaimardi 
  of 
  the 
  Kara 
  Sea. 
  "With 
  Choniostoma 
  and 
  Sphceronella 
  it 
  

   must 
  enter 
  into 
  the 
  aberrant 
  family 
  of 
  the 
  Choniostomatidse. 
  The 
  

   discovery 
  of 
  the 
  still 
  unknown 
  male 
  of 
  Choniostoma 
  will 
  no 
  doubt 
  

   enable 
  us 
  to 
  fix 
  more 
  exactly 
  the 
  affinities 
  of 
  this 
  family. 
  

  

  finally 
  the 
  relations 
  between 
  the 
  Aspidcecia 
  and 
  the 
  Aspido- 
  

   phryxus 
  render 
  it 
  a 
  very 
  probable 
  supposition 
  that 
  Choniostoma 
  is 
  or 
  

   has 
  been 
  parasitic 
  upon 
  a 
  branchial 
  Bopyride 
  of 
  the 
  Hippolyte 
  and 
  

   has 
  usurped 
  its 
  dwelling-place. 
  A 
  memoir 
  with 
  plates 
  will 
  make 
  

   known 
  in 
  more 
  detail 
  the 
  anatomy 
  of 
  Podascon 
  and 
  Aspidcecia, 
  and 
  

   we 
  may 
  be 
  permitted 
  in 
  conclusion 
  to 
  thank 
  MM. 
  Delia 
  Valle 
  and 
  

   A. 
  M. 
  Norman, 
  who 
  have 
  sent 
  us 
  the 
  materials 
  for 
  this 
  investigation 
  

   in 
  an 
  admirable 
  state 
  of 
  preservation.

  Spontaneous 
  Movenu 
  nts 
  of 
  the 
  Style 
  and 
  Stigmata 
  of 
  the 
  Cornflag 
  

   (Gladiolus 
  segctum). 
  By 
  M. 
  C. 
  Musset. 
  

  

  The 
  author 
  notes 
  that 
  movements 
  of 
  the 
  female 
  organs 
  of 
  plants 
  

   are 
  comparatively 
  uncommon 
  and 
  calls 
  attention 
  to 
  an 
  important 
  

   instance 
  in 
  the 
  Cornflag. 
  In 
  the 
  Iridacose 
  the 
  anthers 
  open 
  out- 
  

   wards 
  longitudinally, 
  so 
  that 
  the 
  pollen 
  falls 
  upon 
  the 
  parts 
  of 
  the 
  

   perianth, 
  and 
  can 
  only 
  reach 
  the 
  stigmata 
  by 
  the 
  action 
  of 
  the 
  wind, 
  

   the 
  intervention 
  of 
  insects, 
  &c. 
  In 
  the 
  genus 
  Gladiolus 
  the 
  stjde 
  

   and 
  stigmata, 
  by 
  their 
  movements, 
  get 
  over 
  this 
  difficulty. 
  

  

  The 
  three 
  stamina 
  forming 
  the 
  exterior 
  whorl 
  of 
  the 
  andrcecium 
  

   attain 
  their 
  final 
  length 
  before 
  the 
  styles 
  have 
  commenced 
  their 
  

   growth 
  ; 
  the 
  two 
  posterior 
  lateral 
  ones 
  incline 
  their 
  filaments 
  to 
  the 
  

   right 
  and 
  left 
  of 
  the 
  anterior 
  stamen, 
  so 
  that 
  the 
  three 
  anthers 
  are 
  

   juxtaposed 
  in 
  the 
  same 
  plane. 
  At 
  this 
  moment 
  they 
  turn 
  their 
  

   dorsal 
  surface 
  to 
  the 
  style 
  and 
  they 
  are 
  also 
  3 
  centim. 
  longer, 
  so 
  that 
  

   direct 
  pollination 
  is 
  doubly 
  impossible. 
  The 
  concrescent 
  styles 
  

   situated 
  behind 
  the 
  filaments 
  grow 
  rapidly 
  in 
  the 
  direction 
  of 
  the 
  

   dorsal 
  line 
  of 
  the 
  andrcecium 
  and 
  soon 
  equal 
  the 
  stamina 
  in 
  height 
  ; 
  

   but 
  the 
  filaments 
  bend 
  slightly 
  outwards, 
  the 
  anthers, 
  hitherto 
  in 
  

   lateral 
  contact, 
  separate, 
  and 
  their 
  cells 
  open 
  ; 
  the 
  styles, 
  still 
  

   growing, 
  bend 
  in 
  the 
  same 
  direction 
  ; 
  the 
  three 
  stigmata 
  also 
  sepa- 
  

   rate 
  and 
  move 
  so 
  as 
  to 
  come 
  directly 
  beneath 
  the 
  anthers, 
  from 
  which 
  

   the 
  pollen 
  can 
  then 
  fall 
  only 
  upon 
  the 
  stigmatic 
  papilla?. 
  Direct 
  

   pollination 
  is 
  thus 
  insured.
