The writer proposes to class colour-variations as follows : — 
“ Aberrations, or Heteromorphism. — White: Albinism. Pallid: Xanth- 
ism. Black : Melanism. Sports : Heteropoecilism. Females coloured 
as males : Gynandrocliromism. Both sexes in one individual : Her- 
maphroditism. 
“ Constant Variations , or Orthopcecilism. — Variable species : Polymorph- 
ism. Local variations: Topomorphism. Reversion : Atavism. Two 
static conditions : Dimorphism. Three static conditions : Trimorphism. 
Seasonal variation : Iloroomorphism.”
