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



The type of this species was obtained in Jobi, and there is 

 a typical example from that island collected by Meyer in the 

 British Museum. With this specimen our birds seem to be 

 identical. Up to the present time this was the only example 

 in the collection, and the sex " cJ " appears to have been 

 wrongly determined, for the males are very appreciably 

 larger than the females, as is shown by the following 

 measurements : — 



8 males : wing 63"5-68 mm. ; 3 females : wing 57- 

 62 mm. 



" The Chestnut-backed Flycatcher was nowhere a common 

 species, and was usually observed singly. Like Todopsis 

 bonapartii, it has a pretty habit of raising the tail and de- 

 pressing the wings, and at the same time running up and 

 down some horizontal branch ; this habit was shared by most 

 of the other species of lihipidura met with.'^ — C. H. B. G.

This species is nearest to R. dryas Gould, the type of 

 which came from Port Essington, and is in the British 

 Museum. Like the Australian form, it has very little chest- 

 nut on the tail-feathers, and that is confined to the extreme 

 basal portion, while the under tail-coverts are pale rufous- 

 buff. It is, however, a much larger bird, the chestnut 

 extends further over the crown, and the patch of black 

 white-edged feathers on the fore-neck below the black band 

 is much more extensive. The iris, bill, and legs are brown. 

 Total length 165 mm. ( = 6'5 inches) ; wing 75-77 ; 

 tail 91. 



In R. dryas the wing measures 66-68 mm.
