  along 
  the 
  shore 
  and 
  also 
  in 
  Shag-rookeries. 
  Its 
  linear 
  and 
  very 
  narrow 
  

   wings 
  are 
  almost 
  as 
  long 
  as 
  the 
  abdomen. 
  It 
  can 
  jump, 
  but 
  cannot 
  fly. 
  

   The 
  sexual 
  organs 
  are 
  retracted. 
  

  

  A 
  Puleoc 
  is 
  parasitic 
  upon 
  Halidroma, 
  and 
  one 
  (possibly 
  the 
  same 
  

   species) 
  on 
  Diomedea 
  fuliginosa. 
  

  

  Coleoptera 
  are 
  not 
  uncommon. 
  The 
  larger 
  species 
  seem 
  to 
  have 
  their 
  

   elytra 
  soldered 
  together. 
  There 
  is 
  a 
  small 
  species 
  of 
  the 
  Brachyely 
  tra 
  . 
  

  

  Several 
  species 
  of 
  Nirmiidcv 
  have 
  been 
  obtained. 
  

  

  Two 
  Poduroe 
  (one 
  black, 
  the 
  other 
  white) 
  are 
  plentiful. 
  

  

  There 
  appear 
  to 
  be 
  few 
  species 
  of 
  Spiders, 
  though 
  individuals 
  are 
  

   numerous. 
  Penguins 
  and 
  some 
  of 
  the 
  other 
  birds 
  are 
  infested 
  with 
  Ticks. 
  

   The 
  remaining 
  Arachnida 
  are 
  related 
  to 
  Cribates. 
  

  

  The 
  Crustacea, 
  Annelida, 
  Mollusca, 
  and 
  Echinodermata, 
  in 
  this 
  part 
  of 
  the 
  

   island, 
  have 
  probably 
  been 
  collected 
  by 
  the 
  ' 
  Challenger 
  ' 
  more 
  extensively 
  

   than 
  I 
  have 
  been 
  able 
  to 
  do 
  ; 
  therefore 
  I 
  need 
  not 
  particularize 
  further 
  

   about 
  them 
  than 
  to 
  state 
  that 
  Entomostraca 
  abound 
  in 
  the 
  lakes 
  ; 
  an 
  

   earthworm 
  is 
  common, 
  and 
  a 
  land-snail 
  is 
  very 
  plentiful 
  amongst 
  the 
  rocks 
  

   on 
  the 
  hills. 
  This 
  last 
  appears 
  to 
  appreciate 
  comparative 
  heat, 
  for 
  speci- 
  

   mens 
  obtained 
  in 
  an 
  exposed 
  place, 
  during 
  the 
  frosty 
  weather, 
  were 
  assem- 
  

   bled 
  together 
  for 
  warmth 
  under 
  the 
  drip 
  of 
  an 
  icicle. 
  

  

  In 
  Observatory 
  Bay, 
  Ccelenterata 
  are 
  not 
  numerous. 
  One 
  or 
  two 
  

   species 
  of 
  Actiniidse 
  on 
  the 
  rocks 
  and 
  3Iacrocystis-roots, 
  and 
  an 
  Ilyan- 
  

   thid 
  in 
  mud, 
  are 
  the 
  only 
  Actinozoa 
  I 
  have 
  met 
  with. 
  The 
  Hydrozoa 
  

   similarly 
  have 
  afforded 
  only 
  three 
  species 
  — 
  a 
  Corynid, 
  a 
  Campanularian, 
  

   and 
  a 
  Sertularella. 
  

  

  There 
  are 
  several 
  Sponges. 
  

  

  "With 
  the 
  exception 
  of 
  Limosella 
  aquatica, 
  and 
  perhaps 
  Agrostis 
  ant- 
  

   arctica, 
  I 
  have 
  obtained 
  all 
  the 
  flowering 
  plants 
  and 
  ferns 
  given 
  in 
  the 
  

   * 
  Flora 
  Antarctica 
  ' 
  as 
  indigenous 
  to 
  the 
  island. 
  Besides 
  these, 
  Ranun- 
  

   culus 
  hydrophilus 
  and 
  another 
  species, 
  a 
  Carecc, 
  a 
  Festuca 
  (probably 
  F. 
  

   purpurascens 
  ; 
  but 
  I 
  have 
  no 
  work 
  containing 
  descriptions 
  of 
  the 
  flower- 
  

   ing 
  plants), 
  Polypodium 
  vulgare, 
  a 
  fern 
  allied 
  to 
  Polypodium, 
  and 
  Cysto- 
  

   pteris 
  fragilis 
  have 
  occurred 
  to 
  me. 
  There 
  is 
  also 
  a 
  plant 
  which 
  appears 
  

   to 
  belong 
  to 
  the 
  Juncacese. 
  Lycopodium 
  clavatum 
  and 
  L. 
  selago 
  are 
  com- 
  

   mon 
  about 
  here. 
  None 
  of 
  the 
  Mosses, 
  Hepaticae, 
  or 
  Lichens 
  have 
  been 
  

   worked 
  out 
  as 
  yet 
  ; 
  but 
  amongst 
  them 
  are 
  one 
  or 
  two 
  species 
  of 
  Cladonia, 
  

   and 
  some 
  examples 
  of 
  Lecanora 
  paleacea. 
  Eungi 
  are 
  represented 
  by 
  

   Agaricus 
  (Psalliota) 
  arvensis, 
  Qoprinus 
  atramentarius, 
  and 
  a 
  peculiar 
  para- 
  

   site 
  on 
  Azorella, 
  which 
  grows 
  out 
  from 
  the 
  rosettes 
  in 
  the 
  form 
  of 
  a 
  clear 
  

   jelly, 
  which 
  becomes 
  changed 
  into 
  a 
  firm 
  yellowish 
  substance 
  of 
  indefinite 
  

   form. 
  There 
  are 
  also 
  some 
  Sphceriacei 
  on 
  grass 
  and 
  dead 
  stems 
  of 
  plants. 
  

   At 
  present 
  few 
  additions 
  have 
  been 
  made 
  to 
  the 
  marine 
  flora. 
  The 
  larger 
  

   Algse 
  in 
  Royal 
  Sound 
  are 
  usually 
  not 
  cast 
  upon 
  the 
  shore 
  by 
  the 
  waves, 
  

   and 
  I 
  have 
  almost 
  been 
  entirely 
  dependent 
  upon 
  grapples 
  thrown 
  from 
  the 
  

   rocks 
  for 
  specimens 
  of 
  the 
  more 
  delicate 
  forms.
