544 Mr, G, L. Bates on the Beversed [Ibis, 



two are marked a and h. This number was found, however, 

 only in the bird from which the sketch was made ; in the 

 others only a was present. Overlap contrary. The median 

 under coverts are small and narrow feathers, hidden by the 

 minor coverts. An interesting note was made in the case 

 of the female bird, of the difference of colour between the 

 reversed and the minor under coverts, the latter being green 

 like the general plumage of the bird, while the reversed 

 coverts were pale blue. 



Poicephalus aubryanus. Two specimens examined, Nos. 

 5945 & 5946. 



Major under coverts forming a complete row, with eleven 

 on the manus, and the remicle wanting ; overlap conforming. 



Median under coverts present on the cubitus, with one or 

 two on the manus or at the carpal joint, the two specimens 

 apparently differing in this respect. Median coverts with 

 contrary overlap. 



It is noticeable that in none of the six specimens of 

 Parrots belonging to three species and as many genera, were 

 any major under coverts found with the contrary overlap, 

 nor any median coverts with the conforming one. Further, 

 very little variation was found in the extent of the median 

 row. 



There was in every case an 11th under covert at the tip of 

 the manus, but no 11th remex, or " remicle. '^ 



Caprimulgus ewopceus [?]. One specimen examined, No. 

 5650. 



Major under coverts forming a complete row, with eleven 

 on the manus, and the remicle wanting (unless this "llth 

 under covert" is the remicle instead, as seems unlikely) ; 

 overlap conforming on the cubitus and distal portion of the 

 manus, contrary on the proximal portion of the manus. 



Median under coverts present on the cubitus, with one at 

 the carpal joint, and one besides on the manus ; overlap 

 contrary.
