This new and interesting bird, which I have tbe pleasure of 

 naming after Dr. Otto Finsch, is closely allied to Cassinia rubi- 

 cunda, Hartl., from Gaboon. It is, however, easily to be dis- 

 tinguished : — 



(1.) by tbe fuscous colouring of the upper surface, this being 

 reddish-brown in the Gaboon species ; 



(2.) by the white on tbe outer tail-feathers, which also have 

 wbite shafts underneath. In C. rubicunda tbe tail is dark brown 

 edged with rich rufous, and has no white on it at all; the 

 shafts also are yellowish underneath. 



I now know three species of Dr. Hartlaub's genus Cassinia 

 (Rev. Zool. 1860, p. 82), which may be conveniently disposed 

 as follows : — 



1. Cassinia rubicunda, Hartl., w^ supra. Rectrice extimd rufo- 

 brunned. Hab. Gaboon. (Plate II. fig. 1.) 



2. C.fraseri (Strickl.). Muscicapa fraseri, Strickl., P. Z. S. 

 1844, p. 101 ; Hartl. Orn. Westafr. p. 95. Rectrice extimd 

 pallide fulvo-brunned. Hab. Fernando Po. 



3. C. finschi, nobis ut supra. Rectrice extimd apicem versus 

 albd. Hab. Fantee. (Plate II. fig. 2.) 



In form C.fraseri is intermediate between tbe other two. The 

 tail is fulvous-brown, much paler than in C. rubicunda, which 

 has the tail reddish-brown ; while C. finschi is easily distinguished 

 from either by tbe tail being for tbe most part white.
