  particularly 
  of 
  Trinidad. 
  On 
  these 
  subjects 
  he 
  contributed 
  some 
  

   seventy 
  or 
  eighty 
  memoirs 
  and 
  papers, 
  which 
  are 
  scattered 
  through 
  

   various 
  serials 
  dating 
  from 
  1863 
  to 
  1913, 
  thus 
  covering 
  a 
  period 
  of 
  

   fifty 
  years. 
  He 
  would 
  seem 
  to 
  have 
  been 
  more 
  greatly 
  attached 
  to 
  

   palteoconchology 
  and 
  the 
  recent 
  MoUusca, 
  as 
  his 
  writings 
  were 
  

   certainly 
  more 
  voluminous 
  on 
  these 
  subjects 
  than 
  on 
  other 
  organic 
  

   groups. 
  He 
  first 
  pointed 
  out 
  the 
  undoubted 
  occurrence 
  of 
  Cretaceous 
  

   rocks 
  in 
  Trinidad 
  through 
  his 
  discovery 
  of 
  Trigonia 
  suhcrenulata, 
  

   Orbigny, 
  at 
  Point-a-Pierre, 
  a 
  Pelecypod 
  which 
  had 
  been 
  previously 
  

   chronicled 
  from 
  rocks 
  of 
  similar 
  age 
  at 
  Bogota, 
  South 
  America, 
  

   Many 
  valuable 
  researches 
  were 
  also 
  published 
  by 
  him 
  on 
  the 
  

   Kainozoic 
  Mollusca 
  of 
  Trinidad, 
  Dominica, 
  San 
  Domingo, 
  Jamaica, 
  

   Anguilla, 
  Tobago, 
  and 
  South 
  America 
  (Venezuela). 
  On 
  the 
  recent 
  

   Mollusca, 
  however, 
  he 
  dealt 
  principally 
  with 
  the 
  determination 
  and 
  

   distribution 
  of 
  the 
  terrestrial 
  and 
  fluviatile 
  forms 
  from 
  Trinidad, 
  

   Dominica, 
  Grenada, 
  St. 
  Vincent, 
  and 
  other 
  West 
  Indian 
  islands, 
  

   besides 
  Venezuelan 
  Guiana 
  in 
  Soutli 
  America. 
  His 
  papers 
  on 
  marine 
  

   sliells 
  were 
  devoted 
  chiefly 
  to 
  lists 
  of 
  specimens 
  found 
  in 
  the 
  Gulf 
  of 
  

   Paria, 
  Trinidad, 
  and 
  another 
  describing 
  the 
  second 
  largest 
  example 
  

   of 
  a 
  Pleurotomaria 
  (P. 
  adansoniana), 
  which 
  liad 
  been 
  discovered 
  off 
  

   the 
  Island 
  of 
  Tobago, 
  having 
  an 
  altitude 
  of 
  150 
  millimetres. 
  The 
  

   genus 
  Guppi/a, 
  named 
  after 
  him 
  by 
  Mtirch 
  in 
  1893, 
  was 
  applied 
  to 
  

   a 
  land-shell 
  with 
  Helicoid 
  affinities, 
  being 
  founded 
  on 
  Guppy's 
  

   Conulus 
  vacans 
  from 
  Trinidad. 
  

  

  At 
  the 
  time 
  of 
  his 
  death 
  Mr. 
  Guppy, 
  besides 
  being 
  a 
  member 
  of 
  

   our 
  Society 
  from 
  1894, 
  was 
  a 
  corresponding 
  member 
  of 
  the 
  Zoological 
  

   Society 
  of 
  London, 
  and 
  of 
  the 
  New 
  York 
  and 
  Philadelphia 
  Academies 
  

   of 
  Science. 
  He 
  died 
  within 
  ten 
  days 
  of 
  celebrating 
  his 
  80th 
  

   birthday.
