306 Capt. G. E. Shelley on the 



b^. With a shade of grey on the cheeks ; 



forehead grey ; chin and centre of the 



upper throat white ; upper parts paler ; 



under wing-coverts leaden grey ; with 



a considerable amount of white on the 



upper surface of the tail towards the 



end ; white on the under surface of the 



outer tail-feather 1'5 inch in width . . 2. semitorquatus, var. 

 b. Centre of the abdomen and vent white ; 

 remainder of the abdomen and under tail- 

 coverts pearl-grey, the latter broadly edged 

 with white ; chest of a paler vinous shade, 

 and with all the characters specified in the 

 above T. semitorquatus, var 3. decipiens. 



From the above it would appear to me that T, decipiens 

 and T. semitorquatus may have come from a common origin, 

 at, comparatively speaking, no very remote period ; but, so 

 far as my present knowledge goes, it would, I consider, be 

 very wrong not to recognize T. decipiens and T. semitor- 

 quatus as distinct species.
