   exception 
  perhaps 
  of 
  the 
  Sparrow-Hawks 
  and 
  their 
  allies) 
  

   these

  deserve 
  the

  Death- 
  Valley 
  is 
  a 
  remarkable 
  elongated 
  depression 
  in 
  

   Southern 
  California, 
  near 
  the 
  borders 
  of 
  Nevada, 
  which 
  

   extends 
  some 
  135 
  miles 
  from 
  north 
  to 
  south, 
  and, 
  at 
  its 
  

   lowest 
  point, 
  attains 
  a 
  depth 
  of 
  480 
  feet 
  below 
  the 
  sea-level. 
  

   Dr.

  a 
  party 
  of 
  naturalists 
  explored 
  this 
  valley 
  

   and 
  the 
  adjoining 
  districts 
  in 
  1891,

  the 
  present
