LIST  OF  MAMMALS;  FROM  OKLAHOMA  AND  INDIAN 
TERRITORIES. 


BY    D.    G.    ELLIOT,     F.  R.S.E. 


The  specimens  enumerated  in  the  following  list  were  procured 
by  Mr.  Surber,  the  official  collector  of  the  Field  Museum,  during 
the  past  winter  and  spring  in  the  two  territories  named,  with  the  ex- 
ception of  a  few  obtained  in  the  neighboring  States  of  Texas  and 
Kansas.  The  two  places  in  which  most  of  Mr.  Surber' s  work  was 
accomplished  were  Alva  and  Dougherty.  The  first  is  situated  in 
Wood  County  in  the  northern  part  of  Oklahoma  Territory,  not  far 
from  the  Kansas  line;  the  other  in  Indian  Territory,  about  the 
center  of  the  Chickasaw  Nation.  Three  other  places  where  short 
stays  were  made  were  Noble  on  the  Canadian  river  in  Cleveland 
County  on  the  borders  of  the  two  territories,  Arnettville  in  Noble 
County,  and  White  Horse  Springs,  west  of  Alva.  During  the  prog- 
ress of  his  work  Mr.  Surber  kept  pretty  full  notes  of  the  habits  of  the 
various  species  met  with,  and  these  have  been  embodied  in  the  pres- 
ent paper,  and  are  always  signed  with  his  initials.  In  all  something 
over  three  hundred  specimens  of  mammals  were  secured,  besides  a 
certain  number  of  fish  and  reptiles.

"  Prairie  dogs  were  common,  located  as  usual  in  large  colo- 
nies or  towns.  On  a  large  perfectly  level  expanse  of  prairie, 
south  of  camp  and  quite  near  it,  was  a  colony  of  several  hundred 
Cynomys.  At  the  time  of  my  visit,  the  latter  part  of  May  and 
first  of  June,  the  young  were  just  beginning  to  dig  their  own  bur- 
rows which  were  not  over  one-half  the  size  of  those  of  the  adults. 
Shooting  these  animals  was  very  difficult  until  I  was  shown 
how  to  do  it  correctly,  after  which  it  became  an  easy  matter  to 
secure  them.  From  their  habit  of  sitting  over  the  burrow,  hind 
feet  on  one  side,  fore  feet  on  the  other,  ready  to  drop  down  head 
first  at  a  flash,  it  is  almost  impossible  to  get  them,  for  in  their 
dying  struggles  they  soon  get  beyond  reach  in  the  almost  verti- 
cal holes.  However,  by  circling  around  until  you  can  get  them 
fairly  in  the  back  of  the  head  with  your  shot,  they  drop  hind 
feet  foremost  into  the  hole,  and  all  their  kicking  tends  to  keep 
them  up  instead  of  pushing  them  down.  By  this  method  one 
may  expect  to  secure  specimens.  There  seems  to  be  a  wide 
variation  in  the  color  of  Cynomys^  individuals  of  several  different 
shades  being  found  together  in  the  same  colony.  They  appear 
to  subsist  wholly  on  the  roots  and  stems  of  the  buffalo  grass. 
Some  ranchmen  have  assured  me  positively  that  they  have  seen 
prairie  dogs  kill  the  large  prairie  rattlesnake,  two  or  three  of 
the  rodents  attacking  it  simultaneously  and  biting  it."  (T.  S.)

ing,  or  to  have  migrated  to  some  other  region,  for  but  few  were 
taken,  even  in  localities  in  which  they  were  common  last  sum- 
mer. In  my  opinion,  however,  they  were  hibernating  during 
the  severe  weather  of  January  and  February,  for  the  few  speci- 
mens secured  were  taken  on  nights  when  the  temperature  had 
become  milder.  They  live  in  burrows  very  much  resembling 
those  of  the  Pocket  Mice,  but  somewhat  smaller."  (T.  S.)

Twenty-one  specimens  from  Dougherty,  Indian  Territory. 

"This  interesting  long-tailed  Peromyscus  was  apparently  com- 
mon everywhere,  but  especially  among  the  loose  rock  on  the 
ridges  east  of  Dougherty.  Nothing  much  could  be  learned  of 
their  habits,  but  they  are  apparently  much  the  same  as  the  other 
woodland  species  of  the  genus."  (T.  S.) 

Peromyscus  canus. 

Peromyscus  canus.  Mearn's  Proc.  U.  S.  Nat.  Mus.  Wash. 
1895,  p.  445. 

Fifty-two  specimens.  16  Alva,  20  Noble,  16  White  Horse 
Springs,  Oklahoma  Territory. 

The  specimens  from  Alva  are  typical  canus,  with  the  long  tail 
66-78  mm.  in  length.  Those  from  Noble  have  much  shorter 
tails,  50-69  mm.,  none  equaling  the  length  given  for  the  type 
75  mm.  But  the  general  colors  of  the  pelage  are  practically 
alike,  and  the  skulls  do  not  seem  to  differ,  nor  do  the  young.  I 
have  therefore  considered  them  as  the  same.  The  difference, 
however,  in  the  length  of  the  tails  is  very  conspicuous.  "The 
white-footed  mice  of  White  Horse  Spring  represent  either  two 
•forms,  or  the  young  and  adults  inhabit  a  different  character  of 
country,  never  associating  together.  Invariably  I  found  the 
small  one  on  the  level  prairies,  while  his  big  relative  was  always 
found  among  the  rocks  on  the  high  buttes.  So  far  as  color  is 
concerned  it  would  be  hard  to  distinguish  them  apart,  but  it 
seems  strange  that  their  habitat  should  be  so  different.  Even 
low  down  on  White  Horse  Creek  I  took  two  or  three  specimens 
among  the  gypsum  cliffs,  but  no  small  ones  were  to  be  had 
nearer  than  the  level  prairie.  Both  may  prove  to  be  of  the  same 
species,  but  I  shall  always  have  my  doubts  owing  to  well  marked 
difference  in  their  habits."  (T.  S.)

Thirteen  specimens.  6  Noble,  Oklahoma  Territory;  7  Dough- 
erty, Indian  Territory. 

"The  cotton  rats  were  all  taken  around  the  edge  of  a  field  in 
the  river  bottom  one  and  one-half  miles  north  of  Dougherty. 
Apparently  they  were  tolerably  common,  but  from  some  cause 
would  not  enter  traps  easily.  Most  of  them  appeared  to  be  liv- 
ing in  old  brush  piles  from  which  their  runways  extended  in 
every  direction.  I  was  told  they  destroyed  an  immense  amount 
of  corn  when  in  the  shock,  and  that  they  also  cut  the  hay  in 
stacks  very  badly,  particularly  about  the  base  after  the  manner 
of  the  meadow  voles  (Microtus pennsylvanicus)  in  the  East." 

(T.  S.) 

There  is  considerable  difference  in  the  total  lengths  of  adult 
individuals,  the  measurements  varying  as  much  as  twenty  milli- 
meters, and  the  color  of  the  face  ranged  in  different  specimens 
from  a  dark  gray  through  rufous  to  ochraceous.

Thirty  specimens.  29  from  Alva,  i  White  Horse  Springs, 
Oklahoma  Territory. 

"  The  little  Harvest  Mouse  next  to  Cricetodipus  richardsoni  is 
the  commonest  small  mammal  found  near  Alva,  and  no  matter 
how  cold  the  weather  it  was  never  prevented  from  moving  about. 
There  were  nights  during  my  stay  in  Alva  when  the  blizzard  was 
so  intensely  cold  that  it  was  almost  unbearable,  yet  on  going  to 
my  traps  the  following  day,  I  found  some  of  these  little  fellows 
frozen  hard  as  rocks  in  the  traps,  and  tracks  of  many  others  in 
the  snow.  I  believe  this  species  is  confined  exclusively  to  the 
flat  bottom  land  along  the  Salt  Fork  River,  for  I  failed  to  secure 
a  single  individual  anywhere  on  the  prairie.  During  my  stay  at 
this  place  last  summer  (1898)  I  caught  but  one  Harvest  Mouse 
and  it  was  utterly  ruined  by  the  ants  which  are  a  curse  to  the 
animal  collector  during  the  warm  season."  (T.  S.)

NEST  OF  "NEOTOMA  M.  SURBERI"  UNDER  ROOT  OF  COTTONWOOD  TREE. 


Oct.  1899.     MAMMALS  FROM  OKLA.  AND  IND.  TERRS. — ELLIOT.          295 

Three  specimens  from  Dougherty,  Indian  Territory,  i  Noble, 
Oklahoma  Territory. 

"  This  interesting  little  mouse  was  taken  along  the  edges  of 
the  cotton  fields  among  the  dense  small  growth  of  vines,  bushes, 
etc.,  and  as  all  were  taken  in  the  same  character  of  surround- 
ings, I  am  led  to  believe  it  prefers  this  to  the  .more  open  fields, 
as  do  most  of  the  species  of  this  genus.  One  specimen  was  se- 
cured one  and  one-half  miles  northeast  of  Dougherty.  The  speci- 
men taken  at  Noble,  O.  T.,  in  March  was  also  secured  in  the 
woodland  at  the  edge  of  a  cotton  field. "  It  must  be  a  rare  species, 
as  particular  pains  were  taken  at  Dougherty  to  secure  a  series, 
but  without  any  success  beyond  the  three  specimens."  (T.  S.).

Twenty-five  specimens.  23  from  White  Horse  Springs  ;  2 
canon  3  miles  west  of  Alva,  Oklahoma  Territory. 

Two  specimens  of  this  new  wood  rat  were  first  obtained  by  Mr. 
Surber  near  Alva,  and  one  of  these  served  as  the  type  of  the  sub- 
species. Subsequently  Mr.  Surber  procured  twenty-three  more 
at  White  Horse  Springs,  west  of  Alva  on  the  borders  of  Wood 
and  Woodward  counties.  The  series  of  examples  bear  a 
remarkably  close  resemblance  and  there  is  but  little  difference- 
between  the  adults  and  young,  the  latter  exhibiting  a  slightly- 
deeper  blue  gray.  It  is  a  very  handsome  animal,  the  fur  is 
soft  as  spun  silk  and  it  can  readily  be  distinguished  from  any 
of  its  relatives. 

"This  beautiful  wood  rat  here  called  locally  'Pack  Rat',  was 
first  taken  on  February  2oth  and  on  the  following  day  another 
was  secured,  the  female.  The  day  on  which  I  took  the  first 
specimen  was  perhaps  the  most  delightful  to  me  of  any  in  my 
whole  field  experience,  though  it  was  a  bitter  cold  day,  the 
thermometer  registering  12  below  zero.  I  had  been  tramping 
for  two  weeks  with  this  rat  as  my  object,  going  the  rounds  of 
my  traps  in  blizzards  fully  one-third  of  the  time,  but  all  the 
while  thinking  it  must  be  N.  baileyi,  and  when  at  last  I  secured 
the  first  specimen  and  saw  how  different  it  was  from  any  wood 
rat  with  which  I  was  acquainted,  my  joy  can  better  be  imagined 
than  described.  I  first  saw  signs  of  the  presence  of  Neotomas 
in  a  small  but  deep  canon  two  miles  west  of  Alva,  where  they 
had  a  large  nest  built  in  the  hollow  of  a  large  cottonwood  tree. 


296  FIELD  COLUMBIAN  MUSEUM — ZOOLOGY,  VOL.  i. 

One  of  the  traps  set  at  this  nest  was  carried  off  by  a  rascally 
Prairie  Wolf,  presumably  with  a  wood  rat  in  it.  About  a  week 
later,  in  a  ravine  a  mile  further  west,  I  found  an  immense  fallen, 
hollow  cottonwood  tree,  literally  packed  full  of  sticks,  etc. 
Pulling  and  punching  at  this  mass,  the  young  man  who  was  with 
me  finally  ran*  a  large  rat  out,  which  quickly  disappeared  in  a 
hollow  limb  of  the  same  tree,  but  not  before  I  could  see  it  was 
of  a  bluish  gray  color.  Having  no  axe  with  me,  I  was  compelled 
to  give  up  the  chase,  but  returned  the  next  day  and  set  some 
Schuyler  Rat  Killers  in  and  about  the  trees.  On  looking  around 
after  setting  these  traps,  I  found  about  100  yards  lower  down  the 
'  draw '  a  nest  of  this  rat,  or  another  one.  Out  of  the  hollow 
tree  where  I  first  found  the  rat,  the  male  was  taken  in  a  trap  set 
at  the  front  entrance  to  the  nest.  Not  more  than  30  feet  from 
this  nest  stood  a  large  partially  decayed  cottonwood,  full  of 
holes,  and  this  tree  I  am  positive  held  more  of  the  rats,  as  well 
worn  runways  led  from  it  to  this  nest  and  the  bark  was  much 
worn  on  the  side  of  the  tree  from  the  animals  climbing  up  it, 
but  although  I  kept  traps  set  continually  around  and  near  the 
tree  and  nest  until  my  departure  several  days  later,  I  got  no 
more  Neotomas.  I  took  a  photograph  of  this  nest  and 
measured  it  accurately.  It  was  built  under  the  spreading 
branches  and  within  a  few  feet  of  the  base  of  a  large  cottonwood 
tree  and  was  five  feet  in  diameter  by  two  feet  in  height.  Though 
composed  mainly  of  sticks,  some  of  large  size,  and  leaves,  there 
was  a  large  amount  of  other  material  in  it,  such  as  many  pieces 
of  prickly  pear  cactus  and  heads  of  the  sumach,  sand  burrs, 
horse,  cow  and  coyote  manure,  etc.  Being  very  compactly 
built,  I  should  imagine  if  would  cause  considerable  exertion  on 
the  part  of  a  coyote  or  badger  to  tear  it  open.  There  were  three 
entrances  to  the  nest  near  the  ground,  one  near  the  base  of  the 
tree  and  the  other  two  showing  in  the  photograph.  Each 
entrance  was  about  five  inches  in  diameter,  but  slightly  broader 
than  high.  The  nest  was  against  the  base  of  the  ravine's  wall 
among  the  grass,  and  sprouts  of  some  species  of  '  gum-bark  ' 
bush,  the  sprouts  showing  perfectly  white  where  they  had  been 
denuded  of  their  bark  by  the  rats.  From  the  nest  several 
smoothly  worn  runways  extended  in  as  many  directions,  some 
going  up  the  ravine  through  the  tall,  rank  grass  which  forms  a 
roof  to  the  runway  quite  up  to  the  fallen  tree  where  the  male  was 
taken,  a  distance  of  fully  one  hundred  yards.  Another  runway 
leads  up  the  back  of  the  ravine  to  the  level  prairie  above.  This

rat  must  be  rare,  as  everyone  to  whom  I  showed  the  two  speci- 
mens assured  me  they  had  never  seen  any  like  them.  My  trip 
to  White  Horse  Springs  was  principally  for  the  purpose  of  secur- 
ing a  series  of  this  interesting  form,  and  I  am  happy  to  say  I 
succeeded  in  securing  23  specimens  of  various  ages  and  sizes. 
The  country  about  White  Horse  is  broken  up  by  deep  ravines 
with  here  and  there  rocky  buttes,  some  of  them  being  fully  100 
feet  high.  These  buttes  are  of  many  and  curious  shapes,  some 
being  perfect  cones,  while  others  look  like  immense  houses  with 
a  chimney  at  one  end  ;  such,  for  instance,  being  'Chimney  Butte  ' 
two  and  one-half  miles  north  of  the  spring.  All  of  these  high  buttes 
have  a  deep  ledge  of  rock,  a  sort  of  reddish  sandstone,  near  their 
summits,  forming  cliffs  in  some  places  20  feet  high.  Lower 
down  on  White  Horse  Creek  there  are  deep  canons,  crowned 
with  cliffs  of  gypsum  rock,  with  here  and  there  caves  of  con- 
siderable size.  Evidently  these  gypsum  cliffs  had  at  some  time 
previous  to  my  visit  been  favorite  haunts  of  Neotomas,  but  they 
were  about  abandoned  as  living  places  at  the  time  of  my  visit, 
though  at  some  former  time  they  must  have  been  great  resorts 
from  the  immense  piles  of  sticks  found  there.  I  caught  but  3 
specimens  in  these  cliffs,  all  the  others  being  taken  in  cliffs  on 
the  high  buttes  quite  near  where  I  camped.  Into  the  crevices 
of  these  cliffs  the  rats  had  carried  immense  piles  of  sticks,  cactus 
and  dried  grass  and  sage;  but  nowhere  did  I  find  any  of  the  hay- 
cock style  of  nests  such  as  those  near  Alva,  20  miles  east.  From 
all  that  I  could  learn  of  their  food  habits  they  seemed  to  subsist 
mainly  on  green  and  dried  grass,  seeds  of  sumach,  and  seeds  of 
cactus.  In  fact  this  was  about  all  they  could  get  in  this  semi 
desert  region.  Among  the  loose  rock  under  the  cliffs  the  Neo- 
tomas had  well-beaten  runways  among  the  thick  growth  of  weeds 
and  sage.  This  formed  usually  a  roof  over  the  runways,  and  I 
found  these  to  be  about  5  inches  in  diameter  on  an  average.  I 
believe  this  form  of  rat  to  be  strictly  nocturnal,  as  I  was  never 
able,  even  by  long,  patient  watching,  to  see  one  in  day-time. 
From  all  that  I  could  learn  I  also  believe  them  to  be  migratory 
to  the  extent  of  changing  from  summer  to  winter  quarters,  even 
though  their  migrations  extend  for  only  a  very  short  distance. 
That  the  Neotoma  magister  Baird  of  the  Alleghany  Mountains  so 
migrates  I  have  positive  proof,  though  their  migrations  are 
irregular  and  depend  to  some  extent  on  the  food  supply;  and  I 
believe  this  may  account  for  the  scarcity  of  Neotoma  m.  surberi 
among  the  <<Gyp"  canons  low  down  on  White  Horse  Creek,

which  they  had  deserted  for  higher  cooler  buttes.  At  one  place 
I  took  a  male  and  female  (adults)  and  3  young,  which  probably 
represented  an  entire  family,  but  usually  no  more  than  one  was 
taken  in  a  place.  My  second  visit  to  White  Horse  Spring  was 
made  for  the  purpose  of  crossing  into  the  hills  20  or  25  miles  south- 
west of  that  point  and  south  of  the  Cimarron  River,  but  unfortu- 
nately on  the  day  of  my  arrival  at  White  Horse  the  river  came 
down  with  a  "head  rise,"  and  by  the  next  day  was  out  of  its 
banks.  I  waited  five  days  for  it  to  fall  so  as  to  be  crossed  safely, 
but  at  the  end  of  that  time  it  showed  no  signs  of  receding,  so  not 
wishing  to  remain  at  White  Horse  longer  I  returned  to  Alva.  I 
was  anxious  to  find  how  far  south  of  the  Cimarron  this  species 
could  be  found,  for  from  what  I  was  told  I  believe  its  range  ex- 
tends to  the  westward  from  about  Alva,  between  the  Salt  Fork 
River  on  the  north  and  the  Cimarron  on  the  south.  I  failed  to 
get  any  specimens  east  of  Alva,  so  believe  it  ranges  no  farther 
east  than  that  point."  (T.  S.)

While  resembling  very  closely  in  general  appearance  N.floridana 
Say  and  Ord,  this  rat  can  readily  be  distinguished  by  its  shorter 
tail  and  the  greater  size  of  the  molar  teeth.  "  I  found  a  colony  of 
Neotomas  in  the  cliffs  east  and  north  of  Dougherty,  out  of  which 
I  secured  five  specimens.  They  apparently  carried  no  sticks 
into  their  dens,  as  is  usually  the  case,  and  might  have  been  tran- 
sient visitants  to  this  ledge  of  rock.  However,  they  had  been 
feeding  largely  on  the  acorns  of  the  post-oak  or  black  jack,  as 
gallons  of  the  empty  shells  testified.  The  sixth  wood  rat  was 
taken  along  a  rail  fence  surrounding  a  cotton  field,  in  a  trap  set 
in  a  pile  of  brush.  From  the  immense  number  of  cliffs  in  the 
Arbuckle  Mountains  I  should  judge  it  to  be  a  fine  locality  for 
this  species,  but  they  were  not  very  common  near  Dougherty."

on  the  high  prairie,  and  from  the  number  of  runways  discovered 
may  be  considered  common,  particularly  on  the  prairie.  This 
is  a  species  I  failed  to  get  last  summer  (1898),  or  in  fact  to  see 
any  signs  during  over  four  weeks  collecting  on  the  same  ground."

"  I  was  very  agreeably  surprised  to  find  this  vole  in  the  region 
of  Dougherty,  as  I  hardly  expected  to  meet  the  subgenus  here. 
The  two  specimens  secured  were  both  taken  the  same  day  and 
in  the  same  general  locality — the  river  bottom,  in  which  I  secured 
the  cotton  rats — one  was  taken  in  an  open  runway,  the  other 
from  what  I  supposed  to  be  an  old  mole  burrow  at  the  time  the 
trap  was  set.  After  this  I  trapped  industriously  for  this  species, 
but  failed  to  get  any  more  specimens,  and  as  the  farmers  there- 
abouts did  not  recognize  it  I  am  forced  to  believe  it  is  rare."

"This  Gopher  is  equally  abundant  on  the  prairie,  in  the  sand- 
hills and  on  the  river  bottoms  about  Alva;  everywhere  I  went 
hundreds  of  their  hills  being  in  sight  at  one  time,  particularly 
near  the  river  bluffs.  I  found  their  burrows  everywhere  from 
three  inches  to  two  and  one-half  feet  below  the  surface,  but  deep- 
est usually  on  the  river  bottom,  where  they  worked  beneath  the 
deep,  sandy,  brick-like  soil  in  the  softer  sand  beneath.  On  the 
river  bluffs  in  the  rich  black  soil  their  burrows  would  average 
about  ten  inches  under  the  surface.  They  are  easy  to  catch  in 
properly  set  traps,  but  most  of  the  time  I  was  in  Alva,  in  Jan- 
uary and  February,  the  earth  was  frozen  to  such  a  depth  that  it 
was  utterly  impossible  to  dig  into  their  runs.  However,  one  day 
I  set  a  trap  and  took  a  specimen  when  the  thermometer  regis- 
tered 10  below  zero.  In  my  opinion  this  would  prove  the  species 
to  be  active  all  winter,  for  at  this  time  the  earth  was  frozen  18-22:

"  Kangaroo  rats,  or  sand  rats  as  they  are  called,  are  perhaps 
the  most  abundant  small  mammals  found  in  western  Oklahoma. 
Their  center  of  abundance  seems  to  be  along  the  river  bottom  in 
the  sand  bars  and  small  sand-hills  where  vegetation  is  very  scant. 
They  are  also  found  sparingly  in  the  sand-hills  back  on  the  prai- 
rie, but  never  away  from  the  sand,  as  they  delight  in  it,  and 
from  which  they  appropriately  derive  their  common  name.  They 
live  in  colonies,  and  are  very  industrious  little  animals.  One 
individual  digs  several  holes,  and  by  trying  constantly  to  keep 
the  sand  clear  of  the  burrows  soon  enlarges  them  to  such  an  ex- 
tent that  many  are  fully  six  inches  in  diameter.  This  species  I 
found  active  in  the  severest  winter  weather,  and  during  my  stay 
in  their  range,  that  night  was  an  exception  when  they  were  not 
out  in  the  snow,  either  digging  or  searching  for  food.  During 
one  of  the  severest  blizzards  we  had  early  in  February,  I  caught 
specimens  of  this  species  in  traps  and  saw  tracks  of  numbers  of 
others  in  the  snow,  the  temperature  being  then  22  below  zero. 
At  this  season  they  seemed  to  be  feeding  principally  on  the  seeds 
of  the  cockle  burr  and  sand  burr,  but  last  August  I  found  the 
seeds  of  the  prickly  pear  cactus  formed  a  great  percentage  of  their 
food.  In  fact,  these  hardy  desert  plants  are  about  the  only  thing 
they  have  to  depend  on,  unless  the  so-called  "bunch  grass"  be 
excepted,  on  the  seeds  of  which  they  may  also  feed.  That  they 
can  stand  thirst  for  a  very  long  period  I  have  proved  by  the  few 
I  have  kept  in  captivity.  These  little  animals  make  very  inter- 
esting and  beautiful  pets,  being  perfectly  tame  even  when  first 
caught.  They  can  easily  be  taken  in  box  traps  during  the  sum- 
mer." (T.  S.)

"  Pocket  Mice  are  common  about  Alva,  both  on  the  bottom- 
lands and  the  high  prairie,  but  they  were  evidently  hibernating 
during  my  stay,  and  but  few  specimens  were  taken,  these  being 
secured  on  soft  days  when  the  earth  had  thawed  to  a  certain 
extent.  They  almost  invariably  inhabit  the  unbroken  prairie 
where  they  make  their  burrows  among  the  short  buffalo  grass. 
While  the  burrow  of  this  species  is  equally  as  large  and  in  some 
instances  even  larger  than  the  Striped  Spermophile,  it  can  be  told 
even  at  a  glance  by  its  circular  form  and  being  sunk  perpendicu- 
larly to  a  depth  of  six  or  eight  inches,  whereas  the  Spermo- 
phile's  burrow  is  usually  slightly  flattened  and  goes  into  the 
earth  at  an  angle  of  about  30  degrees.  I  have  almost  invariably 
found,  at  a  distance  of  from  six  inches  to  two  feet  from  their  bur- 
row, little  mounds  of  sand  and  gravel,  varying  in  size  from  a 
quart  to  a  half  bushel,  and  can  only  account  for  their  presence 
by  believing  that  it  is  cast  there  by  these  mice  when  digging 
their  burrows."  (T.  S.)

"This  hare  is  very  abundant  among  the  willow  brush  and  high 
grass  along  the  Salt  Fork  River  bottom-lands,  but  so  far  as  I 
could  learn  was  replaced  on  the  prairies  by  a  smaller  species 
which  frequents  prairie  dog  towns,  living  in  deserted  burrows 
of  these  rodents.  This  species  is  one  of  the  fleetest  runners  of 
the  cotton  tail  group,  and  unless  a  greyhound  has  a  fair  open 
field,  it  will  outrun  the  dog  every  time.  In  my  opinion  they  are 
much  fleeter  than  the  Lepus  melanotis,  and  .harder  to  get  a  shot 
at.  The  two  specimens  secured  were  taken  in  Schuyler  Rat 
Traps  baited  with  corn  and  set  for  'Sand  Rats.'  Some  were 
caught  in  steel  traps  but  were  unfit  for  specimens.  In  some 
small  sand-hills  east  of  the  river,  but  in  the  bottom  land,  this 
hare  was  very  common  among  the  sage-brush,  but  they  usually 
left  their  forms  before  I  could  get  in  shotgun  range  and  only 
afforded  me  a  glimpse  of  their  cottony  tails  before  disappearing.

"  Little  striped  skunks  are  very  common  everywhere  about 
Alva,  being  perhaps  more  numerous  in  the  Kangaroo  Rat  colo- 
nies along  the  river.  I  imagine  their  main  dependence  for  food 
is  this  rat,  whose  burrow  requires  but  little  digging  on  Spilo- 
gale's  part  to  effect  an  entrance,  as  the  skunk's  body  is  very 
slender.  In  fact,  nearly  all  the  specimens  I  obtained  were  taken 
in  what  I  supposed  to  be  the  Kangaroo  Rat  burrows,  and  in 
•every  case  but  one  they  were  caught  in  Schuyler  Rat  Killers. 
These  traps  will  not  kill  a  Spilogale,  for  every  one  secured  was 
caught  fairly  around  the  neck  just  back  of  the  head,  and  they 
were  very  lively  indeed  when  I  went  to  take  them  out,  and  I  was 
compelled  to  silence  their  abrupt  manner  of  greeting  with  a  load 
of  dust  shot  from  my  auxiliary  barrel.  Their  odor  is  very  bad, 
being,  in  my  opinion,  more  disagreeable  than  that  of  the  common 
skunk."  (T.  S.)

A  TRAPPED  BADGER.

"Badgers  are  not  very  common  at  White  Horse;  in  fact,  I 
failed  to  see  a  single  fresh  hole,  and  it  seems  strange  that  they 
were  not  found  in  the  vicinity  of  the  prairie  dog  towns.  A  lack 
of  their  favorite  food — the  Spermophiles — may  to  some  extent 
influence  their  distribution.  East  of  Alva  they  are  quite  com- 
mon, and  it  was  here  I  secured  the  fine  female  sent  to  the 
Museum.  This  badger  had  dug  three  immense  holes  the  night 
before  I  caught  it,  and  in  one  of  them  it  was  taken  in  a  trap 
which  I  had  carefully  concealed  in  the  loose  dirt  well  down  in 
the  burrow.  I  never  saw  a  more  furious  animal,  and  it  gave  me 
no  end  of  trouble  before  I  finally  secured  its  photograph.  The 
burrow  I  opened,  looking  for  young  badgers,  extended  back  for 
twenty  feet,  at  a  depth  of  four  feet  under  the  surface,  and  I  am 
positive  was  the  result  of  only  a  few  hours'  digging.  The  soil 
in  that  place,  however,  was  a  loose,  black  loam."  (T.  S.)

This  is  one  of  the  handsomest  of  the  moles  and  is  probably 
not  rare  in  the  territories  where  the  specimens  were  obtained, 
but  the  weather  was  decidedly  unfavorable  and  this  probably 
was  the  reason  that  so  few  were  taken. 

"The  weather  was  very  cold  during  my  stay  at  Alva,  and  the 
ground  was  so  frozen  I  obtained  but  few  moles.  They  are,  how- 
ever, common  about  this  region  and  apparently  do  most  of  their 
work  in  the  broken  fields,  where  they  have  no  tough  soil  to  con- 
tend with.  In  an  alfalfa  field  I  traced  one  runway  80  paces  or 
about  225  feet,  and  during  this  time  noticed  perhaps  as  many  as 
fifty  short  side  runs,  extending  from  the  main  one.  In  Indian 
Territory  this  mole  is  common  everywhere  about  Dougherty,  but 
luck  seemed  against  my  securing  more  than  one  specimen.  I 
could  find  no  trace  of  its  presence  on  the  hills  anywhere,"  (T.  S.)
