In the striped-quail, a 
new mar 
king which 
first appeared 
in my < 
ments in 1914, the patterns characteristic to striped (S) and quail ( p:j ) are 
apparently combined in contrast to the ordinary striped marking which is an 
apparent combination of striped and normal ( P(J ) (Tanaka, 1914a, p. 15). 
It is evident that the genetic constitution of the ordinary striped is SPQ,, and 
that of the striped-quail is Spft. The following data can only be explained 
by the assumption just given. 
F 2 striped-quails inbred.
