  are 
  angular 
  in 
  all, 
  except 
  a 
  few 
  of 
  the 
  smallest 
  which 
  are 
  badly 
  

   crumpled. 
  This, 
  too, 
  was 
  to 
  be 
  expected, 
  because 
  though 
  they 
  are 
  

   oval 
  when 
  they 
  first 
  appear, 
  both 
  Maas 
  (1909) 
  and 
  I 
  (1909a) 
  have 
  

   found 
  that 
  they 
  are 
  already 
  triangular 
  in 
  specimens 
  of 
  5-6 
  mm.

  Both 
  of 
  the 
  specimens 
  are 
  hexamerous; 
  that 
  is, 
  they 
  have 
  the 
  

   normal 
  number 
  of 
  radial 
  canals. 
  This 
  is 
  worth 
  noticing 
  only 
  because 
  

   the 
  species 
  is 
  very 
  variable, 
  examples 
  with 
  5 
  or 
  7 
  canals 
  often 
  being 
  

   observed.

  This 
  genus, 
  and 
  Vanhoffen's 
  treatment 
  of 
  the 
  forms 
  involved, 
  is 
  

   discussed 
  in 
  detail 
  in 
  my 
  account 
  of 
  the 
  Philippine 
  Medusae, 
  collected 
  

   by 
  the 
  Fisheries 
  steamer 
  Albatross, 
  and 
  as 
  that 
  paper 
  will 
  probably 
  

   appear 
  before 
  this 
  one 
  does, 
  it 
  would 
  be 
  a 
  seedless 
  repetition 
  to 
  go 
  into 
  

   the 
  matter 
  here 
  further 
  than 
  to 
  point 
  out 
  that 
  Vanhoffen 
  has 
  com- 
  

   bined 
  two 
  totally 
  distinct 
  genera 
  under 
  the 
  name 
  Solmaris, 
  and 
  that 
  

   his 
  statement 
  that 
  all 
  Solmarids 
  have 
  gastric 
  pockets 
  is 
  based 
  on 
  

   misapprehension. 
  That 
  there 
  are 
  Solmarids 
  without 
  gastric 
  pockets 
  

   is 
  now 
  well 
  established. 
  Such 
  forms, 
  that 
  is, 
  those 
  with 
  neither 
  oto- 
  

   porpae 
  nor 
  gastric 
  pockets, 
  have 
  been 
  described 
  by 
  Maas 
  (1909, 
  p. 
  34) 
  ; 
  

   and 
  both 
  Mayer 
  (1910) 
  and 
  I 
  have 
  substantiated 
  his 
  account 
  from 
  

   excellent 
  specimens 
  of 
  the 
  well-known 
  Solmaris 
  Jlavescens 
  from 
  the 
  

   Mediterranean. 
  

  

  The 
  present 
  collection 
  contains 
  several 
  specimens 
  of 
  Solmissus, 
  all 
  

   more 
  or 
  less 
  fragmentary, 
  but 
  still 
  well 
  enough 
  preserved 
  to 
  show 
  

  

  I 
  The 
  name 
  Ciinanthldae,iised 
  by 
  Maas 
  (1904) 
  and 
  by 
  me 
  (1909o) 
  is 
  untenable, 
  because 
  Cunantha 
  Uo.ecke\ 
  

   is 
  almost 
  certainly 
  larval 
  Aegina.
