1 9 1 8 . ] Under Wing- Coverts of Birds. 555 



on tlie cubitus are small feathers with downy edges, aud are 

 hidden by the hirger median coverts. As to the overlap 

 in this rowj it is conforming on the cubitus, these small 

 coverts having their distal vanes, which are almost wholly 

 downy, covered not only by the edges of the adjoining 

 coverts, but also by those of the remiges as well, so that 

 they stand, each one sandwiched between the vanes of two 

 remiges ; on the manus the overlap is contrary excepting 

 three or four coverts at the tip of the wing, which are con- 

 forming. 



Median under coverts present on the cubitus, with one 

 also at the carpal joint ; overlap conforming. As these are 

 larger than the major coverts on the cubitus, and have the 

 same overlap as the major coverts on the manus, they appear 

 to form a continuous row with the manual major coverts. 



Turturcena iriditorques. Two specimens examined, Nos. 

 5846 & 5862. 



Major under coverts complete (wing diastataxic), those 

 on the cubitus small ; overlap on the cubitus conforming, on 

 the proximal part of the manus (half or less) contrary ; 

 on the distal part of the manus (half or more) conforming. 



Median under coverts large, present on the cubitus, with 

 one besides at the carpal joint, and still anotlier (which was 

 wanting, however, in one wing) on the niauus; overlap 

 contrary. 



Calopelia puella. Two specimens examined, not saved. 



Major under coverts complete, only ten on the manus 

 (in one specimen there were found only ten manual lemiges, 

 in the other a very small 11th was found) ; on the cubitus 

 the same number, twelve or thirteen, as the remiges, the 

 wing being eutaxic. The coverts of this row on the cubitus 

 are smaller than the median coverts. Overlap of major 

 coverts conforming on the cubitus, contrary on the proximal 

 part (half or less), conforming on the distal part (half or 

 more) of the manus. 



Median under coverts large, present on the cubitus, with 

 one besides at the carpal joint ; overlap contrary.
