"This new form of Flycatcher was only observed in 

 the mangrove-swamps along the coast, where it was not 

 common. Its habits and actions are similar to those of 

 R. Tufidorsar—C. H. B. G. 



The group of Rhipidura to which this species belongs is 

 widely distributed, and includes a number of closely allied 

 forms such as : 



R. ruhrofrontata Ramsay. Lango, Guadalcanar, Solomon 

 Islands. (Type in the British Museum.) 



To R. ruhrofrontata Ramsay, Messrs. Rothschild and 

 Hartert have referred allied birds from Rendova and Gizo, 

 also in the Solomon Group. The British Museum possesses 

 male examples from both these islands, and, as noted above, 

 the type-specimen of R. ruhrofrontata from Guadalcanar, as 

 well as several typical examples procured by Mr. 0. M. 

 AVoodford at Aola, on the same island. The Rendova and 

 Gizo birds differ markedly from the t^^pical R. ruhrofrontata 

 in having the basal half of the tail-feathers chestnut and the 

 ear-coverts hlack. In R. ruhrofrontata the chestnut at the 

 base of the tail-feathers is much more restricted and the 

 ear-coverts are brown like the crown. I propose to name 

 the Rendova bird 



Rhipidura harterti, sp. n. -1 



For the moment I prefer to give it full specific rank. 



Rhipidura threnothorax.
