DISCOGLOSSUS. 125 



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 subtri- 

 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.
