A'ote. — The type of S. tenuirostris, which I have e.xaiuined, was jirocnred by 

 Captain Stnrt, and is a yonng loug-billpd aberration. The name must be used for 

 the South Australian race, which is characterised by its duller head, smaller size 

 and more spotting on the upper-surface, but the slender bill is not constant. 

 Indeed, this feature is more constant in the East Murchison race, as pointed out by 

 Milligan.
