  Mammals 
  from 
  the 
  Island 
  of 
  Tobago, 
  69 
  

  

  appears 
  to 
  be 
  sufficient 
  to 
  warrant 
  the 
  publication 
  of 
  a 
  short 
  

   note 
  upon 
  them. 
  

  

  It 
  has 
  seemed 
  unnecessary 
  to 
  include 
  tlie 
  synonymy 
  of 
  

   these 
  species, 
  as 
  both 
  are 
  treated 
  in 
  considerable 
  detail 
  by 
  

   Glover 
  M. 
  Allen 
  in 
  his 
  recent 
  paper 
  on 
  the 
  mammals 
  of 
  the 
  

   West 
  Indies 
  (Bull.

  Load 
  name. 
  — 
  Manicou 
  Rat 
  ; 
  known 
  on 
  Grenada 
  and 
  the 
  

   Greiiadines 
  as 
  Manicou 
  Gros-yeux. 
  

  

  Material.

  One 
  impiirfect

   skull. 
  

  

  Compared 
  with 
  a 
  specimen 
  of 
  Marmosa 
  chapmanl 
  from 
  

   Trinidad 
  in 
  the 
  collection 
  of 
  the 
  U.S. 
  National 
  Museum 
  this 
  

   example 
  is 
  found 
  to 
  be 
  somewhat 
  more 
  greyish 
  dorsally, 
  

   while 
  the 
  cinnamon 
  along 
  the 
  sides 
  is 
  paler. 
  The 
  ear 
  is 
  

   much 
  smaller, 
  measuring 
  only 
  17 
  mm. 
  in 
  length. 
  The 
  hind 
  

   foot 
  is 
  noticeably 
  smaller. 
  The 
  specimen 
  from 
  Trinidad 
  is 
  a 
  

   male, 
  while 
  there 
  is 
  a 
  possibility 
  that 
  the 
  one 
  from 
  Tobago 
  is 
  

   a 
  female, 
  and 
  a 
  probability 
  that 
  it 
  is 
  young. 
  

  

  Dr. 
  Glover 
  ]\1. 
  Allen 
  states 
  that 
  two 
  s[)ecimens 
  which 
  he 
  

   obtained 
  on 
  Grenada 
  " 
  are 
  identical 
  in 
  size 
  and 
  cranial 
  

   measurements 
  with 
  a 
  topotype 
  of 
  M. 
  chapmani 
  from 
  Caura, 
  

   Trinidad 
  ; 
  they 
  are, 
  however, 
  slightly 
  paler 
  cinnamon 
  along 
  

   the 
  sides.

  Mr. 
  Oldfield 
  Thonias 
  has 
  recently 
  described 
  the 
  Marmoset 
  

   occurring 
  on 
  Tobago 
  under 
  the 
  name 
  of 
  Marmosa 
  tohagi. 
  

   Though 
  the 
  characters 
  separating 
  this 
  form 
  from 
  M. 
  chapmdni 
  

   do 
  not 
  appear 
  to 
  be 
  of 
  much 
  significance, 
  it 
  has 
  seemed 
  best 
  

   to 
  use 
  the 
  name 
  at 
  least 
  until 
  a 
  good 
  series 
  from 
  Tobago 
  is 
  

   available 
  for 
  study. 
  

  

  Bemarks. 
  — 
  Mr. 
  Oldfield 
  Thomas 
  has 
  described 
  the 
  " 
  manicou 
  

   gros-yeux'^ 
  of 
  Grenada 
  under 
  the 
  name 
  of 
  Marmosa 
  grenadce 
  ; 
  

   but 
  Allen 
  can 
  find 
  no 
  difference 
  between 
  the 
  specimens 
  from 
  

   Grenada 
  and 
  those 
  from 
  'i'rinidad 
  except 
  the 
  very 
  slight 
  one 
  

   in 
  the 
  colour, 
  which 
  he 
  says 
  " 
  is 
  apparently 
  not 
  more 
  than 
  

   individual 
  variation." 
  

  

  It 
  is 
  quite 
  possible 
  that 
  the 
  murine 
  opossum 
  was 
  uninten- 
  

   tionally 
  introduced 
  by 
  man 
  into 
  the 
  Grenadines, 
  and 
  perhaps 
  

   into 
  Grenada 
  also, 
  from 
  Trinidad, 
  for 
  its 
  presence 
  in 
  tlie 
  

   fauna 
  of 
  these 
  islands 
  is 
  somewhat 
  anomalous, 
  and, 
  on 
  

   account 
  of 
  its 
  small 
  size 
  and 
  nocturnal 
  and 
  secretive 
  habits. 
  

   It 
  is 
  the 
  most 
  easily 
  carried 
  from 
  place 
  to 
  i)lace, 
  concealed 
  in
