This example with a win-;- of 150 mm, in all probability 

 belongs to the above form, thongh we have no specimens 

 with which to compare it.

The differences between these two races are well set out 

 by Neumann, O. M. 1904, p. 83. The most noticeable 

 difference between our two specimens is the greater amoun 

 o£ vinous flush on the throat and breast of the Red Sea 

 coast bird and the narrower ring of black round its neck. 

 This group, which is very closely allied to the S. vinacea 

 group, is distinguished by the absence of a black loral 

 streak, whiter under wing-coverts, and paler coloration.
