 specimens a faintly l)righter (golden) tinge is still detectable on the 

 centre of the l)reast, at least in certain lights. 



In a limited numljer of specimens another modification of the 

 colour of the imderparts takes place — viz., a spreading of the pale 

 greyish element (set' colour of back) over the anal region and a j«irt or 

 the whole of the flanks (Big Tam))elan, 101,641', '•')<>, i)ai-atv{>es ; Tioni.in.

The darkening of the colour of the under-pai-ts takes phice <piite 

 independently of the modifications of the colour of tiie lia/'k ; that is, 

 l»right-T»ellied or dar]c-l)ellied individuals may cxhjliit any amount of 

 greyish admixture on the bac-k.
