The following description is taken from the specimen sent to me by 

 M. de Selys-Longchamps. 



H. rufula has the top of the head and back metallic black; wings 

 and tail dull black; cheeks and auditory region yellowish grey; nape 

 and lateral parts of the occiput russet; rump tawny red, passing into 

 yellowish white on the posterior half; throat, chest, abdomen, under 

 tail and wing coverts, whitish, washed with russet, especially on the 

 chest and flanks, and finely striated with brown, more distinct on the 

 crop and throat; the terminal moiety of the under tail coverts well- 

 defined metallic black; beak and feet blackish, the latter slender. The 

 external tail feathers have almost always on their inner barb a small, 

 whitish, oval spot, not well defined, and placed slightly in advance 

 of the base of the feather, which is covered by the inferior coverts. 

 M. de Selys informs us that M. Jaubert has a specimen which has a 

 well-marked white spot on one of the great tail feathers, while the 

 other is quite black. 



As I have before mentioned, I am indebted to M. Ed. de Selys- 

 Longchamps for the Grecian specimen which I have figured. I return 

 him my very best thanks for this obligation. The ^^^ is from my 

 own collection, taken by Dr. Kriiper near Smyrna. It is quite white, 

 larger and rounder than that of H. urhica in the next compartment. 



It has also been figured by Jaubert, Rich. Orn.; Dresser, B. of E.
