In  its  internal  anatomy,  as  in  many  of  its  external  characters,  the  Cryptoprocta  ferox 
approaches  the  Cats.  The  stomach  is  a  long  pouch,  strongly  bent  upon  itself  at  its 
posterior  third,  and  slightly  contracted  at  its  first  third,  where  it  lies  upon  the  trihedral 
elongated  spleen.  Its  rounded  end  extends  left  of  the  oesophagus  about  half  an  inch, 
the  diameter  of  the  stomach  being  three  quarters  of  an  inch  at  the  oesophageal  entrance ; 
it  then  contracts  to  about  five  eighths  of  an  inch,  becomes  again  dilated  to  its  previous 
dimensions,  and  bends  upwards,  gradually  narrowing  to  the  pylorus :  the  length  of  the 
first  portion  is  two  inches  and  a  quarter,  of  the  second,  one  and  three  quarters :  fol- 
lowing the  middle  line  of  the  stomach,  its  length  is  three  inches  and  a  half.  Along  its 
first  or  descending  portion  the  stomach  is  furnished  externally,  both  dorsad  and  ven- 
trad,  with  strong  longitudinal  muscular  fibres :  these  scarcely  extend  to  the  curved 
part,  and  are  not  visible  on  the  ascending  portion.  The  length  of  the  small  intestines 
is  four  feet  and  three  inches  ;  of  the  caecum,  an  inch  and  a  sixth  ;  of  the  large  intestines, 
five  inches  and  a  half.  The  cacum  at  its  base  is  broader  than  the  small  intestine  ad- 
joining it,  the  two  together  about  equalling  the  colon  in  capacity  of  tube  :  from  its  base 
it  narrows  gradually  to  its  extremity,  which  is  only  slightly  obtuse ;  its  direction  is 
parallel  to  the  small  intestine. 
The  teeth  in  the  individual  examined  are  of  the  deciduous  class  only,  and  conse- 
quently cannot  furnish  permanent  characters.  It  may,  however,  be  desirable  to  de- 
scribe them.  They  consist,  in  the  upper  jaw,  of  six  closely  set  incisors,  of  which  the 
four  intermediate  are  small,  with  their  crowns  a  little  flattened  and  somewhat  impressed 
transversely  ;  the  outer  incisors  are  much  larger  than  the  intermediate  ones,  and  have 
on  their  external  surface  somewhat  the  appearance  of  canines  ;  they  have  an  internal 
process,  against  which  the  crowns  of  the  corresponding  teeth  of  the  upper  jaAv  close. 
The  canines  are  distant  from  the  incisors,  and  project  from  the  jaw  about  twice  the 
length  of  the  outer  incisors  ;  they  are  curved  backwards.  Immediately  adjoining  to 
the  canine  on  each  side  are  two  small  false  molars ;  the  first  nearly  cylindrical,  with  a 
slight  process  on  the  outer  and  posterior  part  of  its  crown  ;  the  second  having  a  slender 
lengthened  crown,  and  two  roots.  A  space,  equal  in  length  to  the  second  molar,  in- 
tervenes between  it  and  the  third,  which  is  large  and  composed  of  three  sharp,  longi- 
tudinally disposed,  tubercles  ;  the  anterior  having  a  small  process  behind  ;  the  second, 
twice  the  length  of  the  preceding  one,  is  simple  and  directed  somewhat  backwards  ;  the 
third  forms  a  long  transverse  ridge :  the  middle  tubercle  is,  at  its  base,  somewhat 
lengthened  inwards,  but  is  withovit  process  or  spur  in  this  direction.  The  fourth 
molar,  adjoining  the  third,  is  irregularly  triangular ;  its  outer  and  broadest  portion  is
