  Almost 
  everywhere 
  water 
  may 
  be 
  obtained 
  in 
  small 
  quantities 
  from 
  fissures 
  

   and 
  joints 
  in 
  the 
  bed 
  rocks 
  which 
  include 
  crystalline 
  rocks 
  of 
  pre-Triassic 
  

   age 
  and 
  sandstone, 
  shale, 
  and 
  trap 
  of 
  Triassic 
  age. 
  The 
  till

  mantles 
  

   the 
  bed 
  rock 
  of 
  the 
  hills 
  and 
  upper 
  valley 
  slopes 
  yields 
  in 
  general 
  satisfactory 
  

   domestic 
  supplies. 
  The 
  stratified 
  drift 
  or 
  glacial 
  outwash 
  deposits 
  of 
  the 
  

   lowlands 
  yield 
  abundant 
  supplies 
  of 
  water 
  except 
  in 
  the 
  more 
  unfavorable 
  

   topographic 
  situations.

  This 
  paper 
  contains 
  a 
  brief 
  description 
  of 
  the 
  geology 
  and 
  occurrence 
  of 
  

   ground 
  water 
  in 
  a 
  part 
  of 
  Ellis 
  County 
  in 
  western 
  Oklahoma. 
  The 
  region 
  

   is 
  in 
  the 
  semi-arid 
  belt 
  and 
  in 
  years 
  when 
  the 
  precipitation 
  is 
  deficient 
  crops 
  

   may 
  fail. 
  In 
  August, 
  1918, 
  in 
  a 
  well 
  that 
  was 
  being 
  drilled 
  for 
  oil 
  near 
  Gage 
  

   a 
  large 
  flow 
  of 
  artesian 
  water 
  was 
  struck, 
  which 
  it 
  was 
  hoped 
  could 
  be 
  used 
  

   for 
  irrigation. 
  Investigation 
  showed 
  that 
  the 
  water 
  comes 
  from 
  the 
  Permian 
  

   "Red 
  Beds" 
  and, 
  although 
  in 
  sufficient 
  quantity, 
  it 
  is 
  generally 
  so 
  highly 
  

   mineralized 
  that 
  it 
  cannot 
  be 
  used 
  for 
  irrigation. 
  Water 
  of 
  good 
  quality 
  

   can 
  be 
  obtained 
  from 
  the 
  Tertiary 
  rocks, 
  but 
  these 
  rocks 
  do 
  not 
  yield 
  enough 
  

   water 
  to 
  provide 
  for 
  irrigation. 
  The 
  conclusion 
  is 
  reached 
  that 
  water 
  can 
  

   be 
  obtained 
  for 
  irrigation 
  only 
  along 
  the 
  floodplains 
  of 
  the 
  larger 
  streams 
  

   in 
  the 
  area.

   Preoccupied 
  names 
  of 
  five 
  species 
  of 
  birds 
  cause 
  the 
  following 
  nomen- 
  

   clatural 
  changes. 
  The 
  bird 
  commonly 
  known 
  as 
  Dendrocitta 
  sinensis 
  (Latham) 
  

   is 
  renamed 
  D. 
  celadina. 
  The 
  name 
  of 
  the 
  wagtail 
  now 
  called 
  Motacilla 
  longi- 
  

   cauda 
  Riippell 
  is 
  changed 
  to 
  M. 
  rhadinura. 
  The 
  South 
  African 
  warbler, 
  Eremo- 
  

   mela 
  flaviventris 
  (Burchell), 
  is 
  hereafter 
  to 
  be 
  called 
  E. 
  griseoflava 
  perimacha. 
  

   The 
  Indian 
  babbling 
  thrush 
  that 
  has 
  long 
  been 
  known 
  as 
  Crateropus 
  griseus 
  

   (Gmelin) 
  is 
  renamed 
  Ttirdoides 
  polioplocamus 
  , 
  since 
  in 
  addition 
  to 
  the 
  pre- 
  

   occupation 
  of 
  its 
  specific 
  name, 
  the 
  generic 
  name 
  Turdoides 
  Cretzschmar 
  

   must 
  supersede 
  Crateropus 
  Swainson. 
  Furthermore, 
  Arrenga 
  cyanea 
  (Hors- 
  

   field) 
  will 
  henceforth 
  be 
  known 
  as 
  A. 
  glaucina 
  (Temminck).

  Study 
  of 
  Ostinops 
  decumanus 
  shows 
  that 
  there 
  are 
  great 
  individual 
  differ- 
  

   ences 
  in 
  size 
  apparently 
  attributable 
  to 
  age, 
  and 
  this 
  involv^es 
  a 
  remarkable 
  

   variation 
  not 
  only 
  in 
  the 
  length 
  but 
  in 
  the 
  shape 
  of 
  the 
  wing 
  chiefly 
  in 
  males. 
  

   Furthermore, 
  an 
  interesting 
  geographic 
  color 
  variation 
  in 
  which 
  there 
  appear 
  

   wholly 
  or 
  partly 
  yellow 
  feathers 
  scattered 
  throughout 
  the 
  plumage 
  of 
  the 
  

   body 
  and 
  wing 
  coverts 
  indicates 
  an 
  undescribed 
  race 
  in 
  Bolivia, 
  which 
  is 
  

   described

  Ostinops 
  decumanus
