  cuckoo 
  {Ghalcites 
  hasdlis) 
  is 
  pinkish, 
  with 
  a 
  uniform 
  sprinkling 
  of 
  

   tiny 
  reddish 
  spots." 
  Serventy 
  and 
  Whittell 
  ( 
  1948, 
  p. 
  238) 
  , 
  in 
  speaking 
  

   of 
  Chalcites 
  lucidus^ 
  state 
  : 
  "The 
  egg 
  is 
  pale 
  olive 
  in 
  colour, 
  without 
  

   any 
  markings, 
  but 
  this 
  colour 
  can 
  be 
  removed 
  with 
  water, 
  after 
  which 
  

   the 
  shell 
  is 
  found 
  to 
  be 
  light 
  bluish 
  in 
  colour." 
  

  

  Friedmann 
  (1948, 
  p. 
  115; 
  1949, 
  p. 
  519) 
  has 
  called 
  attention 
  to 
  a 
  

   behavior 
  pattern 
  "unique" 
  among 
  parasitic 
  birds 
  in 
  that 
  the 
  "habit 
  

   of 
  feeding 
  of 
  fledged 
  young 
  by 
  adult 
  parasitic 
  cuckoos 
  is 
  known 
  . 
  . 
  . 
  

   only 
  in 
  some 
  four 
  species 
  of 
  the 
  small 
  glossy 
  cuckoos 
  of 
  the 
  Chalcites- 
  

   Chrysococcyx 
  group." 
  However, 
  Moreau 
  (1949, 
  p. 
  537) 
  cited 
  two 
  

   references 
  indicating 
  that 
  adults 
  of 
  Cuculus 
  occasionally 
  feed 
  young 
  

   cuckoos. 
  

  

  "The 
  African 
  glossy 
  cuckoos 
  also 
  have 
  a 
  courtship 
  feeding 
  behavior," 
  

   which 
  "is 
  otherwise 
  known, 
  in 
  cuckoos, 
  only 
  in 
  African 
  forms 
  of 
  

   Clamator 
  and 
  Cuculus'''' 
  (Friedmann, 
  1948, 
  p. 
  115). 
  Since 
  this 
  state- 
  

   ment 
  was 
  published, 
  however, 
  Watson 
  and 
  Bull 
  (1950, 
  p. 
  226) 
  have 
  

   reported 
  observations 
  of 
  Chalcites 
  hicidus 
  which 
  gave 
  them 
  the 
  "im- 
  

   pression 
  . 
  . 
  . 
  that 
  some 
  form 
  of 
  communal 
  display 
  with 
  courtship 
  

   feeding 
  was 
  taking 
  place." 
  These 
  authors 
  do 
  not 
  agree 
  with 
  Fried- 
  

   mann 
  (1949, 
  p. 
  517) 
  that 
  feeding 
  of 
  young 
  by 
  adults 
  has 
  been 
  proved 
  

   for 
  the 
  New 
  Zealand 
  shining 
  cuckoo. 
  

  

  That 
  the 
  species 
  of 
  glossy 
  cuckoos 
  here 
  discussed 
  are 
  closely 
  related, 
  

   biologically 
  and 
  anatomically, 
  is 
  evident 
  from 
  an 
  analysis 
  of 
  the 
  

   data 
  presented. 
  The 
  behavior 
  patterns 
  of 
  courtship 
  feeding 
  and 
  feed- 
  

   ing 
  of 
  fledged 
  young 
  indicate 
  close 
  relationship. 
  Too 
  little 
  is 
  known 
  

   about 
  the 
  detailed 
  life 
  history 
  of 
  these 
  birds 
  to 
  justify 
  further 
  com- 
  

   parison. 
  In 
  morphological 
  characters, 
  also, 
  these 
  species 
  exhibit 
  a 
  

   general 
  uniformity 
  of 
  structure. 
  For 
  the 
  most 
  part, 
  differences 
  in 
  

   muscles, 
  for 
  example, 
  can 
  be 
  ascribed 
  only 
  to 
  size 
  differences 
  of 
  the 
  

   species. 
  

  

  It 
  seems 
  certain 
  that 
  unsatisfactory 
  characters 
  have 
  been 
  used 
  by 
  

   some 
  authors 
  to 
  separate 
  Chrysococcyx 
  and 
  Lampromorpha. 
  Jackson 
  

   (1938, 
  p. 
  500) 
  used 
  shape 
  and 
  length 
  of 
  tail 
  to 
  separate 
  them: 
  Lam- 
  

   yromor'pTia 
  "has 
  the 
  tail 
  much 
  shorter 
  and 
  slightly 
  rounded, 
  but 
  not 
  

   graduated." 
  Priest 
  (1934, 
  p. 
  227) 
  separated 
  them 
  on 
  the 
  basis 
  of 
  

   sexual 
  dimorphism, 
  but 
  this 
  surely 
  was 
  a 
  misprint 
  in 
  his 
  key. 
  In 
  

   establishing 
  the 
  genus 
  '"'' 
  Adamatomu'''' 
  for 
  klaas^ 
  Roberts 
  (1922, 
  p. 
  219) 
  

   stated 
  only 
  that 
  klaas 
  "is 
  much 
  smaller 
  than 
  cwpreusy 
  

  

  Little 
  has 
  been 
  written 
  on 
  the 
  locomotor 
  habits 
  of 
  these 
  species. 
  

   Yet, 
  of 
  seven 
  differences 
  in 
  anatomical 
  structure 
  which 
  might 
  be 
  useful 
  

   for 
  determining 
  relationship, 
  six 
  seem 
  definitely 
  to 
  be 
  correlated 
  to 
  

   functional 
  phenomena. 
  These 
  involve 
  primarily 
  the 
  extent 
  of 
  origin 
  

   or 
  insertion 
  and 
  relative 
  length 
  of 
  belly 
  of 
  the 
  following 
  muscles: 
  

   latissimus 
  dorsi, 
  iliotibialis, 
  extensor 
  proprius 
  digiti 
  III, 
  abductor
