1 9 1 8 . ] Under Wing- Coverts of Birds. 561 



Ispidina picta. One specimen examined, not saved. 



Major under coverts present on the manus^ doubtless ten 

 in number (remiges ten only) ; none whatever on the cubitus, 

 not even rudiments. Overlap on the manus contrary, with 

 the exception of two or three conforming ones at the tip. 

 Wing eutaxic. 



Median under coverts present on the cubitus, with one at 

 the carpal joint ; overlap contrary. 



Mijioceyx lecontei. One specimen examined, No, 5921. 



Major under coverts present on the manus, doubtless only 

 ten ; on the cubitus represented by small down-feathers, so 

 situated in the intervals between the remiges that each is 

 closer to a remex on its proximal than on its distal side, 

 thus differing from the usual position of major under 

 coverts. Overlap on the manus contrary, with the excep- 

 tion of three to five conforming feathers at the tip. 



Median under coverts present on the cubitus, with one at 

 the carpal joint; overlap contrary. 



Halcyon malimbicus. One specimen (immature) examined, 

 not saved. 



Major under coverts present on the manus ; represented 

 on the cubitus by rudimentary feathers, which, however, 

 are not mere down-feathers, and have slender shafts. 

 Overlap on the manus contrary on the proximal portion, 

 conforming on the distal portion (about half). 



Median under coverts present on the cubitus, with one at 

 the carpal joint ; overlap contrary. 



Halcyon badius. Two specimens examined. No. 5906, and 

 another not saved. 



Major under coverts present on the manus, but repre- 

 sented on the cubitus by rudimentary feathers with slender 

 shafts, or, in one of the specimens, by mere small down- 

 feathers. Wing eutaxic. The manual major under coverts 

 have the conforming overlap on the distal half, or more
