" Gynandromorphisin," and Kindred Problems. By E. A. Cockayne, 

 M.D., M.R.C.P., F.E.S. ' Journal of Genetics,' vol. v, 1915. 

 We have received in separate form Dr. Cockayne's latest contri- 

 bution to a fascinating subject, and congratulate the author upon a 

 really valuable addition to our kno\Yledge thereof. He has collected 

 the known instances of gynandromorphism in the recorded cases, and 

 throws much additional light on the association of the phenomenon 

 with heterochroism. He demonstrates how it may be hereditary by 

 direct and indirect descent, and his remarks confirm the observations 

 of many collectors at home and abroad that there are genera decidedly 

 more prone to gynandromorphism than others — e. g. the Lycienid®, 

 and of them the groups Agriades and Polyommatus. It is really 

 extraordinary how dimorphism is so often accompanied by the genesis 

 of individuals structurally associated with both sexes. I recall to 

 mind the large number of true gynandromorphous P. icarus taken 

 on an area less perhaps than a hundred acres by Mr. Oberthlir's 

 collectors at Dompuric-sur-Mer, in the Lower Charente, where also 

 the "whole blue" females of A. corydon and A. thetis — syngrapha 

 and coelestis — are actually in the ascendant. Dr. Cockayne also 

 shows how in-breeding tends to the same result, especially in the 

 case of hybrids, such as the several hybrid races produced by crossing 

 species of the genus Amorpha {Snierinthus). This paper, with its 

 admirable photographic plates, sums up at once our present know- 

 ledge of a subject to which Dr. Cockayne's own observations have 

 contributed not a little, while his lucid style and reasoned scheme of 

 diagnosis help us to grasp technicalities of description too often 

 unintelligible to the lay mind unversed in the methods of advanced 

 scientific research work. A word of unqualified praise must also be'; 

 accorded the woodcuts in the text of dissections and preparations.
