1918.] Under Wing-Coverts of Birds. 545 



Caprimulgus batesi. One specimen examined, not saved. 



Major under coverts exactly as in the last bird, both as 

 regards tlie number and the overlap ; here also the remicle 

 "was wanting. 



Median under coverts present on the cubitus, with one 

 at the carpal joint, but no other on the man us ; overlap 

 contrary. 



Caprimulgus binotatus. One specimen examined. No. 5942. 



Overlap of the major under coverts on the cubitus and on 

 the distal half of the manus conforming, on the proximal 

 half of the manus contrary. 



About the median under coverts no note was made except 

 that they were small. 



Scotornis climacurus. One specimen examined, No. 5645. 



Major under coverts forming a complete row, with eleven 

 on the manus and the remicle wanting; overlap of those on 

 the cubitus, and of the most distal four on the manus, 

 conforming ; of the remainder on the manus contrary. 



Median under coverts present on the cubitus, with the 

 most distal one just at the carpal joint; overlap contrary. 



Macrodipteryx macrudipterus. One specimen examined. 

 No. 5783. 



Major under coverts forming a complete row, with eleven 

 on the manus, if the feather described in my note-book as 

 "a remicle resembling the major under coverts '■' is really 

 a covert, as I now think ; overlap conforming, with the 

 exception of six feathers on the proximal portion of the 

 manus, on one wing only; on the other wing the overlap of 

 the entire row conforming. 



Note the marked difference, as regards the overlap of the 

 manual major under coverts, between the two wings of 

 the same bird, such as was seen in one specimen of Astur 

 melanuleucus. 



Median under coverts present on the cubitus, with one on 

 the manus ; overlap contrary.
