1. GEOCICnLA. 165 



bristles small. Wing with the third primary longest, second pri- 

 mary between the fourth and titth, bastard primary l^O inch. Legs, 

 feet, and claws pale. Length of wing 4-1 inches, tail 3*0, culuieu 

 0-86, tarsus 1-3. 



Nothing is kuown of the changes of plumage which this species 

 may undergo ; but the type specimen may prove to be an example of 

 G. hivittata with an abnormally short bill. 



Sharpe's Ground-Thrush is only kuown from the interior of the 

 Gold Coast of the Gulf of Guinea, in West Africa.

 General colour of the upjier parts bright rufous, shading into dark 

 cinereous on the head ; quills brownish black, the second and third 

 primaries externally edged with dark cinereous, the remaining 

 quills externally edged with bright rufous ; wing- coverts and inner- 

 most secondaries bright rufous ; tail brownish black, the outside 

 feathers edged with rufous. Underparts white, shading into dark 

 cinereous on the chin and cheeks, and suffused with dull yellowish 

 brown on the breast and tiauks. Bill bluish black and rather thick. 

 Wings with the fourth and fifth primaries longest, bastard primary 

 spurious. Legs pale yellowish. Leuglh of wing 4-75 inches, tail 

 2-5, bill from gape 0-87, tarsus 0*1. 



Nothing is known of the changes of plumage. 

 Cassin's Ground-Thrush is only known from the Gaboon a little 

 south of the eijuator, in West Africa. 



The British Museum does not possess an example of this species, 

 and the type in the Philadelphia Museum collected by DuChaillu has 

 been mislaid. No other example is known. It is probably nearly 

 allied to 0. crosslcyi ; but Cassin's description from which the above 

 is taken is somewhat meagre.
