  M. 
  peroneus 
  longus 
  is 
  poorly 
  developed, 
  resembling 
  the 
  structure 
  

   of 
  that 
  muscle 
  in 
  Coccyzus. 
  Fleshy 
  fibers 
  begin 
  some 
  distance 
  (7 
  to 
  

   10 
  mm.) 
  distal 
  to 
  the 
  rotular 
  crest, 
  and 
  the 
  belly 
  does 
  not 
  conceal 
  any 
  

   part 
  of 
  M. 
  tibialis 
  anticus. 
  

  

  M. 
  plantaris 
  is 
  a 
  long, 
  thin 
  muscle 
  whose 
  belly 
  extends 
  about 
  two- 
  

   thirds 
  the 
  distance 
  down 
  the 
  tibiotarsus. 
  

  

  In 
  Chrysococcyx 
  cupreus, 
  M. 
  extensor 
  proprius 
  digiti 
  III 
  is 
  a 
  long 
  

   thin 
  muscle 
  which 
  begins 
  just 
  distal 
  to 
  the 
  proximal 
  articular 
  surface 
  

   of 
  the 
  tarsometatarsus 
  and 
  extends 
  to 
  the 
  distal 
  end 
  of 
  that 
  bone. 
  The 
  

   belly 
  does 
  not 
  increase 
  much 
  distad, 
  as 
  it 
  does 
  in 
  Goccyzua. 
  The 
  muscle 
  

   is 
  similar 
  in 
  origin 
  in 
  Ghalcites 
  hxcidus^ 
  but 
  the 
  fleshy 
  fibers 
  end 
  5.5 
  

   mm. 
  proximal 
  to 
  the 
  insertion. 
  In 
  LaTnproniorpha 
  caprius, 
  the 
  muscle 
  

   arises 
  at 
  the 
  level 
  of 
  insertion 
  of 
  M. 
  tibialis 
  anticus. 
  

  

  M. 
  lumbricalis 
  exhibits 
  its 
  best 
  development 
  in 
  Lampromorpha 
  

   and 
  its 
  poorest 
  development 
  in 
  Chalcites; 
  in 
  the 
  latter 
  genus 
  it 
  is 
  

   limited 
  to 
  the 
  distal 
  half 
  of 
  the 
  tarsometatarsus. 
  

  

  M. 
  obturator 
  internus, 
  similar 
  in 
  the 
  three 
  genera, 
  is 
  triangular 
  in 
  

   shape 
  and 
  has 
  only 
  a 
  small 
  fasciculus 
  arising 
  from 
  inside 
  the 
  pelvis. 
  

  

  Syrinx 
  

  

  The 
  syrinx 
  is 
  tracheobronchial. 
  There 
  is 
  one 
  pair 
  of 
  intrinsic 
  

   syringeal 
  muscles. 
  In 
  Chrysococcyx 
  cupreus 
  and 
  Lampromorpha 
  

   hlaas 
  these 
  muscles 
  insert 
  on 
  the 
  fourth 
  bronchial 
  semiring. 
  This 
  ring 
  

   is 
  not 
  much 
  wider 
  than 
  adjacent 
  rings, 
  but 
  it 
  has 
  the 
  largest 
  diameter 
  

   of 
  any 
  in 
  the 
  bronchial 
  series. 
  The 
  structure 
  is 
  similar 
  in 
  Z. 
  caprius 
  

   and 
  Chalcites 
  lucidus 
  except 
  that 
  the 
  muscles 
  insert 
  on 
  the 
  third 
  semi- 
  

   ring. 
  However, 
  not 
  more 
  than 
  two 
  syringes 
  were 
  suitable 
  for 
  study 
  

   in 
  any 
  one 
  species 
  so 
  I 
  cannot 
  say 
  that 
  the 
  point 
  of 
  insertion 
  is 
  constant. 
  

  

  Viscera 
  

  

  In 
  each 
  specimen 
  the 
  right 
  lobe 
  of 
  the 
  liver 
  is 
  much 
  larger 
  than 
  the 
  

   left 
  lobe. 
  A 
  gall 
  bladder 
  is 
  not 
  evident. 
  The 
  pancreas 
  is 
  bilobed. 
  

   One 
  can 
  obtain 
  only 
  an 
  approximate 
  total-length 
  measurement 
  of 
  the 
  

   intestine. 
  Its 
  total 
  length 
  in 
  millimeters 
  in 
  two 
  specimens 
  of 
  Lampro- 
  

   morpha 
  caprius 
  is 
  220 
  and 
  240 
  ; 
  in 
  two 
  specimens 
  of 
  Chalcites 
  lucidus^ 
  

   160 
  and 
  180 
  ; 
  and 
  in 
  two 
  specimens 
  of 
  Chrysococcyx 
  cupreus^ 
  170 
  and 
  

   260. 
  Only 
  insect 
  remains 
  were 
  found 
  in 
  the 
  stomachs. 
  A 
  peculiar 
  

   feature 
  is 
  the 
  presence 
  of 
  a 
  single 
  caecum, 
  about 
  4 
  mm. 
  long 
  in 
  Chalcites 
  

   and 
  5 
  mm. 
  long 
  in 
  Lampromorpha 
  and 
  Chrysococcyx. 
  

  

  Discussion 
  

  

  The 
  genera 
  Chrysococcyx 
  and 
  Lampromorpha 
  are 
  restricted 
  to 
  

   A.frica. 
  Chalcites 
  is 
  found 
  in 
  Asia, 
  Australia, 
  and 
  New 
  Zealand.
