  MUSEUM. 
  

   Family 
  GYROPID.^. 
  

  

  Similar 
  to 
  the 
  preceding; 
  but 
  the 
  tarsi 
  have 
  only 
  a 
  single 
  claw 
  and 
  the 
  

   species 
  occur 
  on 
  mammals 
  only. 
  

  

  GYROPUS 
  Nitzsch. 
  

  

  G. 
  ovalis 
  Nitzsch. 
  Occurs 
  on 
  the 
  Guinea 
  pig. 
  

  

  G. 
  gracilis 
  Nitzsch. 
  Occurs 
  with 
  the 
  preceding. 
  Of 
  course, 
  these 
  species 
  

   are 
  not 
  really 
  natives 
  of 
  the 
  State, 
  but 
  the 
  host 
  animals 
  are 
  some- 
  

   times 
  raised 
  as 
  pets 
  and 
  for 
  other 
  purposes 
  and 
  the 
  parasites 
  follow 
  

   them, 
  as 
  do 
  those 
  of 
  other 
  domesticated 
  animals.
