Introduction. 



In the Proceedings of the Zoological Society for 1908, p. 67, 

 I published a report on the inheritance of colour in Domestic Pigeons 

 with special reference to reversion. The colours chiefly dealt with there 

 were black and the "reversionary blue" of Darwin, which may be 

 considered as the type classed as "black-chequer" by the fanciers 

 (Plate V of the report), and also the relations of these two forms 

 to white.
