1 9 1 8 . ] Under Winp- Coverts of Birds. 551 



Mediau under coverts wanting. The same kind of very 

 small feathers standing where a row of mediau coverts 

 would be looked for^ was found in this species as iu the 

 last, and here also they were proved to be minor coverts by 

 the position of the attershaft. 



Turacus meinani. One specimen examinedj No. 5560. 

 Major under coverts a complete row ; overlap con- 

 forming. 



Mediau under coverts none. 



Centrupus inonuchus. Two specimeus examined. No. 5545 

 and another not saved. 



Major under coverts complete, numbering ten on the 

 manus and ten or eleven on the cubitus. The cubital portion 

 of the row in both specimens, and in one specimen two or 

 three coverts at the distal end of the manus, had the con- 

 forming overlap ; the remaining coverts on the manus in 

 the one specimen, and all on the manus, so far as noted, 

 in the other, had the contrary overlap. 



Median under coverts wanting. 



Centropus anselli. Two specimens examined, Nos. 5577 & 

 5816. 



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

 The overlap of these, in No. 5816, was found to be con- 

 forming on the cubitus and distal part (about half) of the 

 manus, and contrary on the proximal half of the manus ; in 

 the note on No. 5577 it is stated that the overlap was con- 

 forming only on the distal third of the manus, and contrary 

 on the proximal two-thirds of the manus and also on the 

 cubitus. That all the coverts of this row on the cubitus 

 should have the contrary overlap is so improbable that I 

 think it likely that only some of them on the distal end 

 of the cubitus, next the contrary ones on the manus, were 

 contrary m their overlap, as is the case in some Cuculidse 

 mentioned below, and that seeing some of them so arranged, 

 I hastily concluded that all were so. 



Median under coverts none.
