Member. Copies of this monthly ' Bulletin ' will be published 

 by Mr. R. H. Porter, 18 Princes Street, Cavendish Square, W. 



Dr. H. BowDLER Sharpe was appointed Editor of the 

 ' Bulletin.' 



Mr. Edward Degen read a paper " On some of the main 

 Features in the Evolution of the Bird's Wing/' which was 

 illustrated by diagrams and specimens. After having briefly 

 summarized the pterylography of the wing, ]\[r. Degex in- 

 vited attention to two small feathers in the carpal regiou^ . 

 lying between the cubital and metacarpal remiges. These 

 were considered by the late Mr. Wray to belong, the upper 

 to the median, and the under to the major row of coverts. 

 But Mr. Degen has come to the conclusion that the so-called 

 major covert is really a degenerated remex, whilst tlie 

 '^median" tectrix is neither more nor less than its major 

 covert. In short, Wray's '•'rudimentary'" major covert 

 belongs to the remiges, and his '' median " to the tectrices 

 majores. Mr. Degen proposed to call the covert the "carpal 

 covert," and the undei-lying feather the " vestigial remex." 

 He further pointed out that hitherto the major coverts had 

 been held to lie proximally to their respective remiges, whilst 

 in reality the reverse was the case. 



Finally, and as the result of the foregoing deductions, 

 Mr. Degen advanced a theory with regard to aquincubitalisra 

 and the probable derivation of the cubital remiges from the 

 3rd and 4th metacarpo-digitals. 



A discussion followed, in which Messrs. P. L. Sclater, 

 Henry Seebohm, and W. P. Pycraft took part.
