  Mount 
  Orizaba, 
  Mexico, 
  W. 
  S. 
  Blatchley; 
  the 
  

   same, 
  11,500 
  feet, 
  March 
  (L. 
  Bruner). 
  Originally 
  described 
  from 
  the 
  

   same 
  mountain 
  as 
  collected 
  by 
  INI. 
  Aug. 
  Salle 
  "an 
  pied 
  de 
  la 
  niege." 
  

   Mr. 
  Blatchley 
  informs 
  me 
  that 
  at 
  the 
  time 
  of 
  his 
  visit 
  the 
  snow 
  line 
  

   was 
  at 
  15,000 
  feet, 
  and 
  adds 
  that 
  he 
  took 
  a 
  single 
  specimen 
  of 
  the 
  species 
  

   at 
  13,500 
  feet, 
  "a 
  very 
  few 
  individuals 
  may 
  have 
  been 
  taken 
  as 
  low 
  as 
  

   9,000 
  feet, 
  but 
  the 
  species 
  was 
  common 
  only 
  between 
  10,000 
  feet 
  and 
  

   12,000 
  feet; 
  above 
  12,000 
  feet 
  scarce." 
  

  

  According 
  to 
  statements 
  in 
  the 
  daily 
  press,^ 
  Orizaba, 
  which 
  is 
  of 
  

   volcanic 
  origin, 
  showed 
  signs 
  of 
  a 
  renewal 
  of 
  activity 
  early 
  in 
  March, 
  

   1805, 
  when 
  hot 
  ashes 
  were 
  ejected, 
  the 
  snow 
  disapjjeared 
  Irom 
  the 
  sum- 
  

   mit 
  and 
  the 
  vegetation 
  of 
  the 
  upper 
  part 
  of 
  the 
  mountain 
  was 
  burned. 
  

   Possibly 
  this 
  means 
  the 
  extinction
