AND ALLIED GENERA. 99 



the white hidden shaft-streaks on the back. Bill slender 

 but nevertheless rather strong, nasal aperture oval, placed 

 in front of the nasal groove , rictal bristles long, reaching 

 as far as or slightly surpassing the nostrils, tail a little more 

 graduated than in Trichostoma, much shorter than the 

 wing, but not much more than twice the length of the 

 tarsus, this latter strong, about an inch long, toes mode- 

 rately long, no pale eyebrow. — Six species. 



Range. Tropical West- Africa, including the Upper 

 Congo Region. 



The different species of this genus being so much alike 

 one another in the style of coloration , and having only 

 two species before me, I am unable, without disposing of 

 a larger material, to construct a key and must, therefore, 

 content mj'self with a mere enumeration of the species 

 and their distribution.

I) With this species Capt. Shelley (Ibis 1890, p. 161) identified Turdinus 

 albipechts Rchw. (J. f. O. 1887, p. 307), which species is said by its author 

 to be distinguished from T, fulvescens by the dark brown crown and having 

 throat and centre of breast and abdomen pure white.
