  spirally. 
  Their 
  formula 
  is 
  40 
  x 
  4 
  + 
  4. 
  Each 
  of 
  these 
  springs 
  from 
  a 
  bulbous 
  

   base, 
  bearing 
  a 
  small 
  but 
  distinct 
  black 
  ocellus. 
  Between 
  each 
  pair 
  of 
  tentacula 
  

   is 
  a 
  minute 
  transparent 
  mobile 
  pedunculated 
  tubercle. 
  Down 
  the 
  four 
  gastrovas- 
  

   cular 
  canals, 
  very 
  nearly 
  from 
  their 
  divergence, 
  to 
  the 
  margin 
  of 
  the 
  umbrella, 
  

   run 
  the 
  four 
  linear 
  genital 
  glands, 
  tinged 
  with 
  rose 
  colour. 
  They 
  are 
  very 
  pecu- 
  

   liarly 
  formed, 
  each 
  hanging 
  from 
  the 
  surface 
  of 
  the 
  subumbrella 
  in 
  the 
  shape 
  of 
  a 
  

   pair 
  of 
  undulated 
  membranous 
  curtains, 
  strikingly 
  reminding 
  us 
  of 
  the 
  appear- 
  

   ance 
  presented 
  by 
  Staurophora 
  (so 
  well 
  described 
  and 
  figured 
  by 
  Professor 
  

   Agassiz 
  in 
  his 
  Memoir 
  on 
  the 
  Naked-Eyed 
  Medusae 
  of 
  Massachusetts;, 
  but 
  differ- 
  

   ing 
  in 
  their 
  nature; 
  for, 
  in 
  the 
  animal 
  we 
  are 
  describing, 
  they 
  are 
  assuredly 
  quite 
  

   distinct 
  from 
  the 
  stomach-lobes. 
  The 
  stomach 
  is 
  rather 
  large 
  and 
  quadrangularly 
  

   campanulate, 
  rose 
  coloured, 
  and 
  slightly 
  fimbriated 
  at 
  the 
  margins. 
  

  

  Thaumantias 
  confluents. 
  — 
  To 
  find 
  a 
  new 
  species 
  of 
  the 
  genus 
  Thaumantias 
  

   sufficiently 
  distinct 
  from 
  the 
  numerous 
  and 
  very 
  similar 
  described 
  forms, 
  was 
  

   scarcely 
  to 
  be 
  looked 
  for. 
  In 
  the 
  one 
  before 
  us, 
  however, 
  we 
  have 
  found 
  such 
  a 
  

   desideratum. 
  

  

  The 
  Thaumantias 
  confluens 
  differs 
  from 
  all 
  its 
  British 
  allies 
  in 
  having 
  the 
  

   genital 
  glands 
  continued 
  so 
  high 
  up 
  on 
  the 
  gastrovascular 
  canals, 
  that 
  they 
  all 
  

   meet 
  on 
  the 
  vertex 
  of 
  the 
  umbrella, 
  and 
  form 
  an 
  unbroken 
  cross. 
  

  

  The 
  umbrella 
  is 
  hemispheric, 
  smooth, 
  and 
  colourless. 
  Its 
  margin 
  is 
  fringed 
  

   with 
  pale 
  pinkish 
  tentacula 
  ; 
  the 
  formula 
  of 
  their 
  number 
  being 
  14x4 
  + 
  4. 
  

   Their 
  bases 
  bear 
  very 
  minute 
  black 
  ocelli 
  ; 
  the 
  intertentacular 
  spaces 
  have 
  

   minute 
  tubercle-like 
  bodies 
  on 
  each, 
  some 
  of 
  them 
  being 
  shortly 
  pedunculated. 
  

   The 
  marginal 
  veil 
  is 
  broad. 
  The 
  genital 
  glands 
  are 
  of 
  a 
  pale 
  pink 
  colour, 
  very 
  

   narrow 
  and 
  linear, 
  confluent 
  at 
  their 
  bases, 
  and 
  continued 
  down 
  the 
  upper 
  third 
  

   of 
  each 
  of 
  the 
  four 
  gastrovascular 
  canals. 
  When 
  the 
  creature 
  is 
  in 
  the 
  water, 
  

   they 
  present 
  the 
  appearance 
  of 
  a 
  pink 
  cross. 
  The 
  stomach 
  is 
  very 
  short 
  and 
  

   narrow, 
  and 
  terminates 
  in 
  four 
  lanceolate 
  acute 
  lips. 
  The 
  disk 
  measures 
  nearly 
  

   half-an-inch 
  across. 
  

  

  This 
  delicate 
  and 
  pretty 
  annual 
  was 
  met 
  with 
  not 
  unfrequently 
  off 
  Tober- 
  

   mory, 
  and 
  afterwards 
  near 
  Skye.
