   Lloyd 
  ^ 
  has 
  exammed 
  the 
  types 
  of 
  D. 
  rivers-andersjoni 
  and 
  raniceps 
  

   of 
  Alcock 
  and 
  finds 
  pseudobranchise 
  present, 
  represented 
  by 
  two 
  very 
  

   short, 
  slender 
  filaments. 
  These 
  species 
  agree 
  closely 
  with 
  the 
  Philip- 
  

   pine 
  form. 
  If 
  the 
  characters 
  for 
  Diplacanihopoma 
  are 
  correctly 
  

   given, 
  there 
  would 
  seem 
  to 
  be 
  no 
  doubt 
  that 
  these 
  forms 
  are 
  at 
  least 
  

   subgenerically 
  distinct. 
  For 
  them 
  the 
  name 
  Sarcocara 
  (new 
  sub- 
  

   generic 
  name) 
  is 
  proposed, 
  based 
  on 
  the 
  Philippine 
  species 
  herein 
  

   described.
