  DECAPODA 
  FROM 
  ALBATROSS 
  DREDGINGS, 
  669 
  

  

  tral 
  processes 
  a 
  little 
  narrower, 
  and 
  their 
  teeth 
  fewer 
  in 
  number, 
  thick 
  

   and 
  obtuse, 
  and 
  the 
  terminal 
  segment 
  ot 
  the 
  palpus 
  is 
  a 
  little 
  narrower. 
  

   The 
  mandibles 
  are 
  in 
  fact 
  more 
  like 
  those 
  of 
  A. 
  eximea. 
  The 
  fold 
  on 
  the 
  

   ventral 
  side 
  near 
  the 
  tip 
  of 
  the 
  eudopod 
  of 
  the 
  first 
  maxilla 
  is 
  armed, 
  in 
  

   place 
  of 
  the 
  two 
  to 
  four 
  short 
  spines 
  in 
  A. 
  Agassizii, 
  with 
  a 
  series 
  often 
  

   to 
  twelve 
  setae, 
  of 
  which 
  the 
  proximal 
  are 
  stout, 
  and 
  somewhat 
  spini- 
  

   form, 
  but 
  the 
  distal 
  very 
  slender. 
  The 
  two 
  lobes 
  of 
  the 
  distal 
  segment 
  

   of 
  the 
  protognath 
  and 
  the 
  endognath 
  of 
  the 
  second 
  maxilla 
  are 
  slightly 
  

   more 
  slender 
  than 
  in 
  A. 
  Agassizii. 
  The 
  anterior 
  lobe 
  of 
  the 
  scaphognath 
  

   is 
  much 
  longer 
  and 
  narrower, 
  contracted 
  near 
  the 
  middle 
  and 
  slightly 
  

   expanded 
  at 
  the 
  obtuse 
  and 
  somewhat 
  truncated 
  tip, 
  while 
  the 
  posterior 
  

   lobe 
  is 
  slightly 
  broader. 
  The 
  endopods 
  and 
  exopods 
  of 
  the 
  maxillipeds 
  

   are 
  much 
  longer 
  and 
  more 
  slender 
  than 
  in 
  A. 
  Agassizii, 
  but 
  these 
  ap- 
  

   pendages 
  do 
  not 
  differ 
  in 
  other 
  respects. 
  The 
  propodus 
  and 
  dactylus 
  

   of 
  the 
  first 
  gnathopod 
  are 
  a 
  little 
  more 
  narrowed 
  distally, 
  and 
  the 
  line 
  

   of 
  articulation 
  between 
  them 
  slightly 
  less 
  oblique 
  than 
  in 
  A. 
  Agassizii. 
  

   The 
  second 
  gnathopods 
  differ 
  scarcely 
  at 
  all. 
  

  

  The 
  perceopods 
  are 
  similar 
  to 
  those 
  of 
  A. 
  Agassizii, 
  but 
  are 
  a 
  little 
  

   more 
  slender, 
  somewhat 
  less 
  hairy, 
  and 
  the 
  proportions 
  of 
  the 
  segments 
  

   slightly 
  different 
  ; 
  the 
  carpus 
  in 
  the 
  second 
  pair 
  is 
  nearly 
  as 
  long 
  as 
  the 
  

   merus 
  and 
  much 
  longer 
  than 
  the 
  chela, 
  which 
  is 
  considerably 
  shorter 
  

   and 
  much 
  more 
  slender 
  than 
  in 
  the 
  first; 
  and 
  the 
  carpi 
  in 
  the 
  third, 
  

   fourth, 
  and 
  fifth 
  pairs 
  are 
  relatively 
  shorter 
  than 
  in 
  A. 
  Agassizii. 
  

  

  The 
  first 
  and 
  second 
  somites 
  of 
  the 
  pleon 
  are 
  rounded 
  above, 
  but 
  the 
  

   third 
  and 
  fourth 
  are 
  very 
  strongly 
  compressed 
  dorsally 
  and 
  project 
  in 
  a 
  

   very 
  high 
  and 
  sharp 
  crest, 
  highest 
  at 
  the 
  articulation 
  between 
  the 
  two 
  

   somites 
  and 
  on 
  the 
  third 
  produced 
  into 
  a 
  very 
  long, 
  slender, 
  compressed, 
  

   and 
  spiniform 
  tooth 
  which 
  is 
  arched 
  over 
  nearly 
  or 
  quite 
  the 
  whole 
  length 
  

   of 
  the 
  fourth 
  somite, 
  which 
  is 
  itself 
  without 
  any 
  carinal 
  tooth. 
  The 
  

   fifth 
  and 
  sixth 
  somites 
  are 
  sharply 
  carinated 
  dorsally, 
  but 
  the 
  carina 
  

   does 
  not 
  project 
  in 
  a 
  tooth 
  or 
  spine 
  on 
  either. 
  The 
  pleura 
  are 
  of 
  about 
  

   the 
  same 
  form 
  as 
  in 
  A. 
  Agassizii, 
  but 
  are 
  somewhat 
  less 
  deep. 
  

  

  The 
  telson 
  is 
  very 
  long 
  and 
  slender, 
  only 
  very 
  obscurely 
  sulcated 
  

   above, 
  armed 
  with 
  seven 
  or 
  eight 
  pairs 
  of 
  small 
  dorsal 
  aculei, 
  and 
  tipped 
  

   with 
  three 
  to 
  five 
  slender 
  spines 
  between 
  a 
  pair 
  of 
  much 
  larger 
  lateral 
  

   ones. 
  

  

  The 
  uropods 
  and 
  pleopods 
  are 
  nearly 
  as 
  in 
  A. 
  Agassizii, 
  but 
  the 
  ovate 
  

   inner 
  lamelliform 
  ramus 
  of 
  the 
  first 
  pleopod 
  of 
  the 
  male 
  is 
  a 
  little 
  nar- 
  

   rower 
  and 
  the 
  marginal 
  stylet 
  reaches 
  slightly 
  beyond 
  the 
  tip 
  of 
  the 
  

   lamella 
  itself.
