19^8.] Under Wing- Coverts of Birds. 5 49 



The two rows of reversed coverts iu the Rails are inserted 

 close together, aud have the same overlap. 



Guttera plumiferu. Six specimens examined, Nos. 5567, 

 5568, 5569, 5617, 5666 & 5667. 



Major under coverts large, forming a complete row ; the 

 number on the manus undoubtedly ten, as an 11th would 

 have been noted it found ; overlap of the whole row, in all 

 cases, conforming. 



Median under coverts very small, not equalling the minor 

 coverts which are themselves small; found only on the 

 cubitus, or, in one case, on the cubitus with one at the joint 

 and one ou the manus besides. These coverts are so narrow 

 and far apart as, in some cases, to have no overlap ; but 

 where the overlap could be made out, it was also conforming, 

 like that of the major coverts. 



Francolinus squamatus. Two specimens examined, not 

 saved. 



Major under coverts a complete row, about ten on the 

 manus, and twelve on the cubitus; overlap conforming. 



Median under coverts small, but not so small as in 

 Guttera, present on the cubitus with one at the carpal 

 joint ; overlap contrary. An interesting fact noted about 

 these small median coverts, in one of tiiese Prancolins, is 

 that they have af tershafts. 



Francolinus lathami. Three specimens examined, No. 5794, 

 and two others which were not saved. 



Major under coverts a complete row, ten on the manus. 

 The overlap of these, in the first, and also in the last 

 specimen examined, was found to be conforming through- 

 out; in the other specimen all these coverts had the 

 conforming overlap excepting three on the proximal end 

 of the manus, in both wings alike, which had the contrary 

 overlap. 



Median under coverts in two specimens (they were 

 inadvertently overlooked in the other) small, but not 

 extremely small ; present on the cubitus, with one at the
