  Mr. 
  D. 
  Robertson 
  brought 
  this 
  species 
  under 
  my 
  notice 
  

   last 
  summer, 
  when 
  he 
  also 
  kindly 
  gave 
  me 
  specimens. 
  It 
  is 
  

   not 
  here 
  described 
  because 
  I 
  believe 
  that 
  he 
  will 
  himself 
  

   shortly 
  do 
  so. 
  It 
  may 
  be 
  mentioned, 
  however, 
  that 
  I 
  have 
  

   confirmed 
  his 
  identification 
  by 
  actual 
  comparison 
  of 
  his 
  speci- 
  

   mens 
  with 
  those 
  kindly 
  given 
  me 
  by 
  Herr 
  J. 
  Sparre 
  Schneider 
  

   from 
  Tromso, 
  with 
  which 
  specimens 
  the 
  Clyde 
  examples 
  

   entirely 
  agree.

  Rostrum 
  extending 
  beyond 
  the 
  first 
  joints 
  of 
  the 
  antennules. 
  

   Antennules 
  having 
  the 
  three 
  joints 
  of 
  the 
  peduncle 
  of 
  nearly 
  

   equal 
  length, 
  each 
  more 
  slender 
  than 
  the 
  preceding, 
  filament 
  

   equal 
  in 
  length 
  to 
  the 
  last 
  two 
  joints 
  of 
  the 
  peduncle, 
  com- 
  

   posed 
  of 
  five 
  long 
  articulations. 
  Antennae 
  slender 
  and 
  short 
  ; 
  

   peduncle 
  exceeding 
  that 
  of 
  antennules 
  by 
  nearly 
  the 
  last 
  

   joint, 
  which 
  is 
  equal 
  in 
  length 
  to 
  the 
  penultimate; 
  filament 
  

   very 
  slender, 
  4-5-jointed, 
  equal 
  in 
  length 
  to 
  the 
  last 
  joint 
  of 
  

   the 
  peduncle. 
  First 
  gnathopods 
  (fig. 
  1) 
  with 
  wrist 
  anteriorly 
  

   produced 
  into 
  a 
  wide 
  rounded 
  lobe, 
  which 
  reaches 
  forward 
  to 
  

   the 
  commencement 
  of 
  the 
  palm 
  ; 
  hand 
  obovate, 
  widest 
  in 
  the 
  

   centre, 
  where 
  the 
  palm 
  commences, 
  which 
  is 
  very 
  oblique 
  ; 
  

   finger 
  slender, 
  simple, 
  as 
  long 
  as 
  the 
  palm. 
  Second 
  gnatho- 
  

   pods 
  (fig. 
  2) 
  very 
  like 
  the 
  first, 
  but 
  the 
  hand 
  slightly 
  larger 
  

   and 
  rather 
  more 
  elongated. 
  All 
  the 
  perseopods 
  with 
  very 
  

   long 
  and 
  nearly 
  straight 
  nails 
  (fig. 
  3), 
  which 
  about 
  equal 
  the 
  

   propodos 
  in 
  length 
  ; 
  propodos 
  much 
  longer 
  than 
  carpus. 
  

   Penultimate 
  perreopods 
  (fig.

  with 
  a 
  row 
  of 
  setse 
  down 
  the 
  

   middle 
  of 
  the 
  basos. 
  Last 
  perteopods 
  (fig. 
  5) 
  with 
  the 
  basos 
  

   small, 
  elongated, 
  pear-shaped, 
  equally 
  produced 
  anteally 
  and
