Abstract
FEW animals lend themselves more readily to breeding work than the silkworm moth, and many valuable contributions to our knowledge of their genetics have been made by Japanese workers, among whom Dr. Tanaka has been one of the most successful. The present memoir deals with the inheritance of a number of characters. It is in part an amplifIcation of data previously published by the same author, and in part a collection of new material. Tanaka has dealt for the most part with larval characters. He has worked out in detail the heredity of the patterns peculiar to the various races where his analysis has led him to the detection of seven Mendelian factors. Certain of these are inherited independently, but there are others forming one of those little groups about which there is at present such keen discussion in connection with multiple a¢llelomorphs. In the present case there are four characters belong-ing to the group, viz. Striped, moricaud, normal, and plain (or, in the absence of the P factor, striped quail, moricaud quail, quail, and pale quail). As in the other cases of similar nature, either the hypothesis of multiple allelomorphs or that of complete coupling covers the facts equally well.
