  are 
  spirally 
  beset 
  with 
  short 
  bristles 
  (Pl. 
  I, 
  fig. 
  8); 
  the 
  first 
  

   ■joint 
  is 
  greatest 
  and 
  broadest, 
  the 
  last 
  seven 
  long 
  and 
  narrow. 
  

   The 
  whole 
  length 
  of 
  the 
  onter 
  antennfe 
  is 
  a 
  little 
  shorter 
  

   than 
  the 
  length 
  of 
  the 
  animal. 
  

  

  The 
  labrum 
  fornas 
  a 
  large 
  triangulär 
  prominence 
  at 
  the 
  

   base 
  of 
  the 
  rostrum 
  (Pl. 
  I, 
  fig. 
  10). 
  

  

  The 
  Mandihulce 
  (Pl. 
  II, 
  fig. 
  12) 
  are 
  large 
  and 
  well 
  de- 
  

   veloped, 
  broad 
  at 
  the 
  bases, 
  decreasing 
  to 
  the 
  tops 
  and 
  strongly 
  

   arched; 
  the 
  left 
  mandibula 
  has 
  two 
  denticulated 
  processes 
  at 
  

   the 
  top, 
  the 
  right 
  has 
  one 
  (Pl. 
  II, 
  fig. 
  13). 
  Under 
  these 
  are 
  

   two 
  bundles 
  of 
  strongly 
  serrated 
  bristles, 
  8 
  — 
  10 
  in 
  each, 
  

   and 
  a 
  long, 
  single 
  bristle. 
  Then 
  follows 
  the 
  molar 
  tubercle, 
  

   "which 
  is 
  rounded, 
  very 
  prominent, 
  and 
  armed 
  at 
  the 
  under 
  

   margin 
  with 
  two 
  short, 
  strong 
  teeth. 
  The 
  mandibular 
  palp 
  is 
  

   the 
  representative 
  of 
  the 
  endopodite; 
  it 
  is 
  long 
  and 
  well 
  

   developed, 
  as 
  long 
  as 
  the 
  mandible 
  itself. 
  It 
  consists 
  of 
  three 
  

   joints 
  and 
  is 
  fixed 
  on 
  a 
  rounded 
  tubercle 
  on 
  the 
  side 
  of 
  the 
  

   mandible, 
  which 
  gives 
  it 
  the 
  appearance 
  of 
  being 
  four-jointed. 
  

   The 
  first 
  joint 
  is 
  long, 
  with 
  a 
  few 
  hairs 
  atthe 
  upper 
  margin; 
  

   the 
  second 
  is 
  the 
  longest, 
  and 
  ciliated 
  at 
  the 
  outer 
  side 
  ; 
  

   the 
  last 
  is 
  the 
  broadest; 
  at 
  the 
  top 
  it 
  is 
  deeply 
  hollowed, 
  

   the 
  hollow 
  being 
  surrounded 
  with 
  movable,finely 
  ciliated 
  bristles 
  

   (Pl. 
  II, 
  fig. 
  15), 
  possibly 
  serving 
  as 
  an 
  organ 
  of 
  sraelling. 
  

  

  The 
  first 
  pair 
  of 
  maxillce 
  (Pl. 
  II, 
  fig. 
  16) 
  consist 
  of 
  a 
  

   greatj 
  rounded, 
  basal 
  joint, 
  the 
  protopodite, 
  and 
  two 
  foliaceous 
  

   plates 
  of 
  insequal 
  size. 
  The 
  outer 
  plate, 
  the 
  exopodite, 
  is 
  

   broad 
  and 
  stout, 
  finely 
  ciliated 
  on 
  the 
  outer 
  and 
  inner 
  sides, 
  

   with 
  the 
  top 
  obliquely 
  truncate 
  and 
  armed 
  with 
  7 
  — 
  10 
  strong, 
  

   denticulate 
  spines 
  (Pl. 
  II, 
  fig. 
  17 
  and 
  18). 
  The 
  inner 
  plate, 
  the 
  

   endopodite, 
  is 
  as 
  long 
  as 
  the 
  outer, 
  but 
  narrower, 
  richly 
  

   provided 
  with 
  ciliated 
  hairs 
  at 
  the 
  arched 
  top. 
  

  

  The 
  second 
  pair 
  of 
  maxilla' 
  (Pl. 
  II, 
  fig. 
  19) 
  is 
  greater 
  and 
  

   more 
  developed. 
  They 
  consist 
  of 
  a 
  protopodite, 
  produced 
  

   at 
  the 
  inner 
  upper 
  side 
  into 
  a 
  flat 
  plate 
  or 
  oblong 
  lamina 
  

   richly 
  supplied 
  at 
  the 
  inner 
  margin 
  with 
  hairs 
  and 
  bristles, 
  

   and 
  of 
  two 
  narrower 
  plates, 
  which 
  articulate 
  with 
  the 
  proto- 
  

   podite. 
  The 
  last 
  two 
  plates, 
  the 
  endopodite 
  and 
  the 
  exopo- 
  

   dite, 
  are 
  long, 
  feebly 
  arched, 
  finely 
  ciliated 
  at 
  the 
  margins 
  

   and 
  armed 
  at 
  the 
  tips 
  with 
  5—6 
  denticulated 
  spines 
  (Pl. 
  II, 
  

   fig. 
  20 
  and 
  21), 
  The 
  endopodite 
  is 
  longer 
  than 
  the 
  exopodite.
