﻿DISCOGLOSSUS.

  The 
  pupil 
  is 
  described 
  as 
  roundish 
  or 
  triangular 
  ; 
  

   in 
  its 
  contracted 
  condition 
  it 
  varies 
  considerably 
  

   according 
  to 
  individuals. 
  It 
  is 
  never 
  absolutely 
  

   round, 
  for 
  it 
  forms 
  an 
  angle 
  below, 
  whence 
  a 
  sub 
  tri- 
  

   angular 
  form 
  results. 
  I 
  have 
  seen 
  specimens 
  in 
  which 
  

   the 
  vertical 
  diameter 
  somewhat 
  exceeds 
  the 
  horizontal, 
  

   so 
  that 
  the 
  fully 
  contracted 
  pupil 
  might 
  be 
  termed 
  

   vertically 
  pear-shaped, 
  or, 
  the 
  upper 
  border 
  forming 
  

   an 
  open 
  angle, 
  kite-shaped.
