Abstract
MR. WIGLESWORTH in the above note hardly does more than, recapitulate the (?) arguments advanced in the “Birds of Celebes.” He does not offer any explanation of the crucial difficulties indicated in the review; why “mechanical attrition on objects,” or by the wind, is effective only in so few cases throughout the class Aves when so many species are subject to the necessary conditions; why, for instance, the species of Palaeornis (belonging to the same sub-family as Prioniturus), or those of the genus Irissor, do not conform to the “law”; and why one sex of a species may have “sabre wings,” or spatulate ornaments in various situations, and the other sex not.
