  on 
  

  

  the 
  terga 
  in 
  shape, 
  but 
  only 
  three-fourths 
  as 
  long; 
  their 
  tips 
  

   turned 
  outwards 
  and 
  projecting 
  laterally, 
  their 
  inner 
  margin 
  

   overlapping 
  the 
  occludent 
  margin 
  of 
  the 
  terga 
  for 
  a 
  consider- 
  

   able 
  distance. 
  Rostrum 
  prominent, 
  triangular, 
  recurved. 
  

   The 
  two 
  subrostals 
  similar 
  in 
  shape, 
  but 
  smaller 
  and 
  much 
  

   less 
  prominent 
  ; 
  the 
  lower 
  valve 
  larger 
  and 
  more 
  prominent 
  

   than 
  the 
  upper. 
  Latera 
  transverse, 
  triangular, 
  of 
  no 
  great 
  

   size, 
  prominent 
  at 
  the 
  tips. 
  Subcarina 
  resembling 
  the 
  

   rostrum, 
  but 
  less 
  than 
  half 
  as 
  long. 
  

  

  Peduncle 
  much 
  shorter 
  than 
  the 
  capitulum, 
  compressed, 
  

   almost 
  triangular 
  in 
  lateral 
  view, 
  covered 
  with 
  almost 
  nodular 
  

   subimbricate 
  plates 
  arranged 
  somewhat 
  irregularly. 
  

  

  Cirri 
  very 
  long 
  and 
  slender, 
  feebly

  The 
  external 
  characters 
  of 
  this 
  barnacle 
  are 
  so 
  peculiar 
  

   that 
  I 
  have 
  ventured 
  to 
  describe 
  it 
  without 
  dissecting 
  the 
  

   unique 
  specimen, 
  on 
  which 
  I 
  have 
  not 
  succeeded 
  in 
  finding 
  

   any 
  degenerate 
  males. 
  I 
  understand 
  that 
  this 
  specimen 
  will 
  

   be 
  deposited 
  in 
  the 
  British 
  Museum.

  External 
  appearance 
  as 
  in 
  the 
  Fernando 
  Po 
  E. 
  alleni, 
  of 
  

   which 
  this

  appear 
  to 
  be 
  the 
  mainland 
  representative. 
  

   General

  above 
  dull 
  rufous 
  fawn,

  greyish, 
  the

  whitish. 
  Tail
