  tal 
  end 
  of 
  the 
  segment 
  itself. 
  The 
  outer 
  flagellum 
  is 
  very 
  stout 
  in 
  both 
  

   sexes, 
  and 
  tapers 
  rapidly 
  to 
  a 
  very 
  slender 
  tip, 
  reaching 
  to, 
  or 
  a 
  little 
  

   beyond, 
  the 
  tip 
  of 
  the 
  antennal 
  scale. 
  The 
  inner 
  flagellum 
  is 
  very 
  slen- 
  

   der, 
  and 
  slightly 
  longer 
  than 
  the 
  outer. 
  The 
  antennal 
  scale 
  is 
  shorter 
  

   than 
  the 
  dorsum 
  of 
  the 
  carapax, 
  a 
  little 
  more 
  than 
  a 
  third 
  as 
  broad 
  as 
  

   long, 
  and 
  has 
  the 
  tip 
  more 
  elongated 
  than 
  in 
  the 
  last 
  species. 
  The 
  fla- 
  

   gellum 
  of 
  the 
  antenna 
  is 
  very 
  slender, 
  subcylindrical, 
  and 
  much 
  longer 
  

   than 
  the 
  body 
  of 
  the 
  animal. 
  

  

  The 
  endopod 
  of 
  the 
  second 
  gnathopod 
  reaches 
  nearly 
  to 
  the 
  tip 
  of 
  the 
  

   antennal 
  scale 
  ; 
  the 
  distal 
  and 
  proximal 
  of 
  the 
  three 
  segments 
  of 
  which 
  

   it 
  is 
  composed 
  are 
  approximately 
  equal 
  in 
  length; 
  the 
  middle 
  segment 
  

   is 
  about 
  two-fifths 
  as 
  long 
  as 
  the 
  proximal, 
  and 
  the 
  exopod 
  scarcely 
  

   reaches 
  to 
  the 
  middle 
  of 
  the 
  proximal 
  segment 
  of 
  the 
  endopod 
  and 
  is 
  

   very 
  slender. 
  The 
  first 
  perseopods 
  reach 
  to 
  near 
  the 
  tips 
  of 
  the 
  peduncles 
  

   of 
  the 
  antennse 
  ; 
  the 
  carpus 
  and 
  chela 
  are 
  together 
  as 
  long 
  as 
  the 
  rest 
  

   of 
  the 
  endopod; 
  the 
  chela 
  is 
  about 
  once 
  and 
  two-thirds 
  as 
  long 
  as 
  the 
  

   carpus, 
  slightly 
  stouter, 
  about 
  a 
  fourth 
  as 
  broad 
  as 
  long, 
  and 
  the 
  digits 
  

   slender 
  and 
  a 
  little 
  less 
  than 
  half 
  as 
  long 
  as 
  the 
  whole 
  length 
  of 
  the 
  

   chela. 
  The 
  second 
  perseopods 
  are 
  very 
  slender 
  and 
  reach 
  considerably 
  

   beyond 
  the 
  antennal 
  scales; 
  the 
  ischium 
  and 
  merus 
  are 
  subequal 
  in 
  

   length; 
  the 
  carpus 
  is 
  a 
  little 
  less 
  than 
  twice 
  as 
  long 
  as 
  the 
  merus, 
  and 
  

   composed 
  of 
  eight 
  segments; 
  the 
  chela 
  is 
  nearly 
  cylindrical 
  and 
  about 
  

   once 
  and 
  two-thirds 
  as 
  long 
  as 
  the 
  distal 
  segment 
  of 
  the 
  carpus, 
  and 
  

   no 
  stouter. 
  The 
  third, 
  fourth, 
  and 
  fifth 
  peraeopods 
  are 
  nearly 
  alike, 
  and 
  

   about 
  as 
  long 
  as 
  the 
  second; 
  the 
  meri 
  and 
  propodi 
  are 
  subequal 
  in 
  

   length, 
  and 
  the 
  meri 
  are 
  armed 
  with 
  three 
  to 
  seven 
  spines 
  along 
  the 
  

   distal 
  part 
  of 
  the 
  lower 
  edge; 
  the 
  lower 
  edges 
  of 
  the 
  propodi 
  arc 
  

   clothed 
  with 
  a 
  few 
  plumose 
  hairs, 
  and 
  firmed 
  with 
  several 
  very 
  slender 
  

   spines 
  ; 
  the 
  dactyli 
  are 
  approximately 
  a 
  fourth 
  as 
  long 
  as 
  the 
  propodi, 
  

   slightly 
  curved, 
  regularly 
  tapered 
  to 
  an 
  acute 
  tip, 
  and 
  armed 
  along 
  the 
  

   lower 
  edge 
  with 
  a 
  regular 
  series 
  of 
  spinules. 
  

  

  The 
  pleon 
  is' 
  somewhat 
  geniculated 
  and 
  slightly 
  compressed 
  dorsally 
  

   at 
  the 
  third 
  somite, 
  but 
  none 
  of 
  the 
  somites 
  are 
  earinated. 
  The 
  telson 
  

   is 
  a 
  little 
  shorter 
  than 
  the 
  sixth 
  somite, 
  evenly 
  rounded 
  above, 
  and 
  

   regularly 
  tapered 
  to 
  a 
  narrow 
  truncated 
  tip 
  armed 
  with 
  six 
  slender 
  

   spines, 
  of 
  which 
  the 
  sublateral 
  pair 
  are 
  much 
  larger 
  than 
  the 
  lateral 
  

   and 
  median. 
  

  

  The 
  eggs, 
  in 
  the 
  alcoholic 
  specimens, 
  are 
  approximately 
  1.0 
  by 
  0.8™ 
  '" 
  

   in 
  longer 
  and 
  shorter 
  diameter. 
  

  

  Many 
  of 
  the 
  specimens, 
  after 
  long 
  preservation 
  in 
  alcohol, 
  show 
  dark 
  

   bands 
  of 
  pigment 
  spots 
  across 
  the 
  antennal 
  scales, 
  uropodal 
  lamellae, 
  

   and 
  somites 
  of 
  the 
  pleon.
