  acronnt 
  of 
  tliose 
  gathered 
  by 
  Miss 
  Cobb, 
  in 
  Lively 
  Island, 
  

   wliicli 
  is 
  situated 
  just 
  ofl" 
  the 
  mainland, 
  due 
  south 
  of 
  

   Choiseul 
  Sound, 
  of 
  the 
  P]ast 
  Falklands. 
  

  

  At 
  the 
  outset, 
  a 
  brief 
  explanation 
  of 
  the 
  configuration 
  of 
  

   this 
  group 
  may 
  be 
  necessary. 
  

  

  Two 
  large 
  islands, 
  divided 
  by 
  a 
  narrow 
  sound, 
  running 
  

   N.E. 
  by 
  S.W., 
  are 
  respectively 
  called 
  the 
  West 
  and 
  East 
  

   Falklands, 
  the 
  latter 
  being 
  the 
  larger, 
  with 
  an 
  area 
  of 
  

   3000 
  square 
  miles 
  as 
  against 
  2300. 
  It 
  is 
  also 
  considerably 
  

   broader, 
  while 
  the 
  length 
  of 
  each 
  is 
  almost 
  the 
  same 
  (say, 
  

   between 
  80 
  and 
  90 
  miles). 
  Both 
  islands 
  are 
  mountainous 
  : 
  

   Mount 
  Adam, 
  in 
  the 
  West 
  Falklands, 
  attains 
  2315 
  feet 
  in 
  

   altitude, 
  while 
  in 
  the 
  corresponding 
  island 
  Mount 
  Usborne 
  is 
  

   slightly 
  lower 
  (say, 
  2245 
  feet). 
  This 
  last 
  also 
  contains 
  the 
  

   majority 
  of 
  the 
  iidiabitants, 
  Stanh'y 
  being 
  the 
  largest 
  — 
  in 
  

   fact, 
  the 
  only 
  — 
  town. 
  It 
  is 
  not 
  surprising, 
  therefore, 
  that 
  

   travellers 
  have 
  in 
  the 
  majority 
  of 
  cases 
  been 
  content 
  to 
  visit 
  

   the 
  East 
  Island 
  alone, 
  and 
  that 
  the 
  equally 
  important 
  

   westerly 
  neighbour 
  is 
  almost 
  unworked 
  and 
  only 
  partially 
  

   explored. 
  

  

  We, 
  indeed, 
  understand 
  from 
  Mr. 
  Vallentin 
  tliat 
  the 
  

   collections 
  of 
  Mollusca 
  (Marine, 
  Terrestrial, 
  and 
  Fluviatile) 
  

   made 
  by 
  him 
  in 
  1910-11, 
  which 
  form 
  the 
  subject 
  of 
  this 
  

   paper, 
  are 
  the 
  first 
  that 
  have 
  been 
  brought 
  from 
  this 
  locality, 
  

   and 
  this 
  fact 
  should 
  render 
  the 
  accompanying 
  catalogue 
  of 
  

   higher 
  interest 
  than 
  usual, 
  even 
  though 
  the 
  majority 
  are 
  well- 
  

   known 
  species. 
  

  

  Mr. 
  Vallentin 
  has 
  also 
  kindly 
  submitted 
  to 
  us 
  his 
  notes 
  on 
  

   the 
  geography, 
  climatic 
  conditions, 
  and 
  other 
  details, 
  which 
  

   it 
  is 
  best 
  to 
  transcribe, 
  unaltered, 
  in 
  his 
  own 
  words, 
  as 
  

   follows 
  :

  Notes 
  on 
  the 
  Collection. 
  

  

  "All 
  these 
  Mollusks 
  were 
  obtained 
  on 
  the 
  north-west 
  side 
  

   of 
  the 
  West 
  Falklands. 
  

  

  "There 
  are 
  no 
  land-locked 
  harbours 
  like 
  Stanley 
  Harbour, 
  

   but 
  the 
  coast-line 
  abounds 
  in 
  very 
  numerous 
  inlets 
  of 
  

   varying 
  length, 
  and 
  there 
  are 
  many 
  islands 
  past 
  which 
  the 
  

   tides 
  I'ush 
  with 
  wild 
  fury. 
  In 
  several 
  places, 
  such 
  as 
  Beef 
  

   Channel 
  and 
  West 
  Point 
  Pass, 
  the 
  pace 
  is 
  great 
  during 
  the 
  

   springs, 
  8-10 
  miles 
  an 
  hour, 
  and 
  when, 
  coupled 
  with 
  this, 
  

   a 
  strong 
  wind 
  is 
  blowing, 
  a 
  terrific 
  sea 
  rages. 
  As 
  a 
  

   natural 
  consequence, 
  animal 
  life 
  is 
  comparatively 
  scarce, 
  

   oidy 
  the 
  strongest 
  forms 
  being 
  able 
  to 
  cope 
  with 
  such 
  wild 
  

   and 
  savage 
  surroundings. 
  

  

  " 
  By 
  far 
  the 
  most 
  sheltered 
  place 
  in 
  this 
  district 
  is 
  lioi/ 
  

   Cove, 
  where 
  a 
  fair 
  amount 
  of 
  dredging 
  was 
  accomplished.
