See this & only other good description admired in a paper article "Difficulties of the Theory of Natural Selection" Month 1869.

[Mivart, St George Jackson.] 1869. Difficulties of the theory of natural selection. The Month 11 (July): 35-53; 11 (August): 134-153; (September): 274-289. [Darwin Pamphlet Collection reviews 145] PDF Darwin cited this in Descent 1: 413, n27: "See an ingenious article entitled, "Difficulties of the Theory of Natural Selection," in the 'Month,' 1869. The writer strangely supposes that I attribute the variations in colour of the Lepidoptera, by which certain species belonging to distinct families have come to resemble others, to reversion to a common progenitor; but there is no more reason to attribute these variations to reversion than in the case of any ordinary variation."
