PLATE XXXVI. 



Diagram A. Showing moult of metacarpo-digital remiges I. and II., or a and h, also 

 their corresponding equivalents VIII. and IX., or «', V , on the cubital 

 portion. 



Diagram B. Illustrates the anomalous case peculiar to the moult of metacarpo- digitals 

 III., IV., and v., or c, d, and e, a triplet of remiges which has no corre- 

 sponding equivalent on the cubital portion at this stage of development. 



Diagram C. Stage of development of previous diagram in a more advanced condition 

 of moult, besides which remex VI. ox f, or the next in turn, is shown. 



On the cubital portion of the left side are seen also the remiges I., X., and 

 VII., lettered /',/", and /"' respectively, the triplet of flight-feathers which 

 restores the temporary asymmetry formed by c, d, and e on the hand-portion, 

 as shown in diagram B. 



Diagram D. Showing moult of metacarpo-digital VII., or g. The moult of its corre- 

 sponding remex II., or g', is indicated at this stage by being shed off. This 

 stage forms one of transition between /j /',/",/'" to that of ^, g'.
