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



Barbntula leucolaima (six specimens) and B. subsrdphurea 

 (five specimens). 



Reversed under coverts one continuons row, with no extra 

 one at the carpus noted — certainly none in some cases ; 

 number on the manus ten, on the cubitus about ten ; overlap 

 contrary^ excepting on a varying fraction, usually half or 

 more, of the manual part of the series at the distal end^ 

 where it is conforming. 



Barbatula erythronota. Seven specimens examined, Nos. 

 5644, 58.24; 58il, 5909, 5929, 5930 & 5936. 



Reversed coverts present on the cubitus and on the manus, 

 without anything, in most cases, to show that the two por- 

 tions of the single row belong morphologically to different 

 series ; but in No. 5824 an extra reversed under covert at 

 the carpal joint was found on both wings, and again in No. 

 5929 such an extra one was found on one wing only. This 

 extra covert is in front of, and smaller than, the 1st covert 

 on the manus, like that marked a in the figure (p. 560) of 

 the Kingfisher (^Ispidina leucogaster), and it seems to be an 

 indication that the cubital reversed coverts in the Barbets, 

 as in the Kingfishers, are really the median coverts which, 

 though generally confined to the cubitus, occasionally extend 

 distally by one more feather, thus continuing the row a little 

 past the end of the major coverts on the manus. Overlap 

 of these cubital or median coverts contrary, as is also that 

 of the proximal end (half or generally less than halt') of the 

 manual or major coverts ; of the remaining major coverts, 

 on the distal half, or more, of the manus conforming. 



Trachyleemus purpuratus. Two specimens examined, cot 

 saved. 



Reversed under coverts forming an apparently continuous 

 row, with ten on the manus and ten or eleven on the cubitus ; 

 no extra one noted. Overlap contrary, excepting those on 

 the distal portion, half or more, of the manus, which are 

 conforming. 



Though in the Barbets there is found only a single 

 apparently continuous row of reversed coverts and the rudi-
