L), in the free margin of theduplicature of the skin in which these muscles are found.By practice we soon learn the best way of doing this,and in the case of all ordinary sized birds, our left handsoon learns how to hold the wing in such a way that theparts to be examined are kept on the stretch, thus faci-litating our examinations and study, which latter maynow be undertaken. Professor Garrod chose the wing of Icterus vulgaristo illustrate the arrangement of the patagial muscles in thePasseres, and it will be seen by an examination of his 112 THE MYOLOGY OF THE RAVEN. figure given below (Fig. 35 quin.) that he found in thatspecies the tendon of the dermo-tensor patagii merging

We would naturally expect this to be the case, asIcterus and the Eaven are members of nearly relatedfamilies.
