1 91 8.] Under Wing- Coverts of Birds. 565 



Lybius bidentatus. Four specimens examined, No. 5635, 

 and three others not saved. 



Reversed under coverts forming one continuous row on 

 both parts of the wing, without anything in their appear- 

 ance or situation to show that they belong to different 

 series, there being no extra one at the carpal joint; they 

 number about twelve on the cubitus, and I think ten on the 

 manus, as an under covert of the remicle would have been 

 noted if one had been present. Overlap of these coverts 

 contrary on the cubitus and the adjacent part of the manus, 

 conforming on the remainder, from half to three-quarters, 

 of the manus. 



Tricholdema fiavipunctatwn. One specimen examined, 

 No. 5902. 



Reversed under coverts one continuous row with no extra 

 one at the carpus ; overlap contrary excepting on the distal 

 half of the manus, where it is conforming. 



Gymnobucco peli. One specimen examined, not saved. 



Reversed under coverts one continuous row with no extra 

 one at the carpus, numbering ten on the manus and about 

 twelve on the cubitus ; overlap of those on the cubitus and 

 the next two on the manus contrary, of the remainder on 

 the manus conforming. 



Buccanodon duchaillui. Three specimens examined, 

 No. 5549, and two others not saved. 



Reversed under coverts one continuous row with no extra 

 one at the carpus, numbering doubtless ten on the manus, 

 and about twelve on the cubitus ; these latter and the next 

 ones on the manus contrary in overlap, the remainder, 

 varying in number from eight to five, of those on the 

 manus conforming. 



Barbatula stellata. Three specimens examined, not saved. 



Reversed under coverts one continuous row with no extra 

 one at the carpus (unless overlooked) ; overlap contrary 

 excepting the distal half of the manus, where it is con- 

 forming.
