 K. ToYAMA (Bui. Assoc. -Sen. Japon, 1908, Xo. 200, pp. 1-12; Ztscin: Induktirc 

 Abstani. u. Vcrcrbtingslchre, 1 {1909), Xo. 3, pp. 179-188). — Finding red worms 

 to suddenly arise from a cross between two normal black breeds, the author con- 

 ducted experiments in view of working out the laws of their inheritance, the 

 details of which are here given. The following are the conclusions arrived at: 



"(1) The sport ' red worms ' may arise from the normal black breed by cross- 

 ing which apparently brings about the segregation of the dominant character ; 

 (2) the red worm thus produced remains constant from its first appearance; it 

 is recessive toward the ordinary black worms and segregates from the latter 

 according to the Mendelian law of heredity; and (3) sometimes it happens that 

 the segregation of both characters is not complete as in the case observed by 

 Correns in plants."
