156 Mr. W. R. Ogilvie-Grant on Birds 



Iris dark brown ; bill and feet black. 



In five adult males the wing measures from 102-104 mm. 

 ( = 4-0-4-l inches). 



In six adnlt females the wing measures from 96-99 mm. 

 (z= 3- 7 5-3- 9 inches). 



Immature birds have some sandy feathers round the nape, 

 and the greater and median wing-coverts are tipped with 

 rufous. 



This widely spread species has been separated into a 

 number of subspecies by recent authors. The type of 

 R. tyicolor (Vieill.) was said to have been procured in the 

 island of Timor, but as the species has not since been met with 

 there^ Mr. Stresemann has substituted Sydney, New South 

 Wales, as the type-locality. As the differences characterising 

 the various forms which have been recognised are entirely 

 a matter of size, I have re-measured all the specimens in the 

 British Museum, and give below the condensed results. 

 It should be remembered that the male is always larger than 

 the female, and that in many instances the sex of the 

 specimens has not been ascertained.
