548 Mr. G. L. Bates on the Reversed [Ibis, 



Snrothrvra bonapartei. One specimen, No. 5958. 



Major niuler coverts a complete row with undoubtedly 

 only ten on the manus (only ten remiges M'ere found) ; 

 overlap of most contrary, but some at either end of the row, 

 near the elbow and near the tip of the wing, apparently 

 conforming in overlap. 



Median under coverts present on the cubitus, with a small 

 oue at the joint or on the manus ; overlap contrary^ unless 

 some of the coverts near the elbow have the conforming 

 overlap, like the major coverts. 



The wings of this bird also are eutaxic as regards the 

 under coverts, though diastataxic as regards the upper 

 ones. 



Podica jacobi. One specimen. No. 5685. 



Major under coverts a complete row, with probably eleven 

 on the manus, and only ten remiges. (The note made at 

 the time was thus expressed, "A remicle with white bar 

 and white tip like the under coverts.") Overlap of these 

 coverts on the manus contrary, on the cubitus apparently 

 also contrary, but so interrupted by feathers in the moult 

 that it could not be certainly made out. 



Median under coverts present on the cubitus and one at 

 the joint, or on the manus ; overlap not made out. 



Podica camerunensis. One specimen, No. 5943. 



Major under coverts a complete row, but number on the 

 manus not observed, though the presence of a remicle 9 mm. 

 long is noted on each wing. Overlap contrary on the manus 

 and distal third of the cubitus, conforming on the proximal 

 two-thirds of the cubitus. 



Median under coverts present on the cubitus, and one at 

 the joint, or on the manus ; overlap of all on the left wing, 

 and of most on the right contrary, but that of some on the 

 cubitus of the right wing conforming. 



The wing in this bird was eutaxic. 



The Rails (including Podica) are unique among the birds 

 investigated in that, in efery case, the whole or the greater 

 part of the major under coverts have the contrary overlap.
