In A I03'i5 (ex 4-m. x 4-m.) 3-moulting variants attain about 45% of 
the whole family, and yet they do not inherit the acquired character, namely 
they are mere somatic variants. 
Several other examples in which 3-moulters appeared in small numbers in 
the families descended from 4-moulting parents, are given below.

1) The reciprocal cross of this produced only 4-moulters (441 in number) (A 2oyi5).
