1 9 1 8 . J Under Wing- Coverts of Birds . 5 67 



meiitaiy major under coverts found on the Kingfishers and 

 Bee-eaters liave quite disappeared, and the extra carpal 

 reversed covert, or most distal median covert, has lu most 

 cases disappeared also ; yet the occasional presence of this 

 feather, as well as the analogy of the Kingfishers, shows 

 that the cubital portion of the single row consists of median 

 coverts, and the manual portion of the major coverts. 



Indicator exilis. One specimen examined, No. 5880. 



Reversed under coverts one continuous row on cubitus 

 and manus, with no extra one at the carpus; number on the 

 manus undoubtedly nine only, as only nine manual leniiges 

 were found. Overlap of these under coverts contrary, ex- 

 cepting a few on the distal end of the manus, which are 

 conforming. 



With regard to the point of junction of the manual and 

 the cubital reversed under coverts, a more exact note was 

 made on this specimen than on most. The position of the 

 1st cubital under covert is in front and rather to the distal 

 side of the base of the first cubital remex (and so also of all 

 the series on the cubitus), thus making two coverts in the 

 interval between the bases of the 1st manual and the 1st 

 cubital remiges, although neither is in front of the other 

 as witii the extra covert at the carpus frequently noted. 

 Though, unfortunately, notes on this point were not made 

 in other cases, it is probable that this position of each 

 cubital under covert rather to the distal side of its remex is 

 the universal one in this and allied birds, and if so this is an 

 additional indication that these are the median and not the 

 major coverts. The position of each manual reversed covert 

 on the proximal siiie of its remex is likewise an indication 

 that the manual ones are the major coverts. 



[Note the positions, where both series of reversed coverts 

 are present, in diagram under Pteronetta hartlaubi, p. 535.] 



Produtiscus insignis. One specimen examined, No. 5768. 



Reversed under coverts one continuous row, with contrary 

 overlap excepting the distal half of the manus, where the 

 overlap is conforming.
