у  GEOCICHLA COMPSONOTA, Cassin. 
CASSIN'S GROUND-THRUSH. 
Geocichla compsonota, Cassin, Pr. Philad. Acad. 1859, p. 42; Seebohm, Cat. Birds Brit. Mus. 
v. p. 165 (1881). 
Chametylas compsonota, Heine, J. f. O. 1859, p. 425. 
Turdus compsonotus, Gray, Hand-1. B. i. p. 260, no. 3799 (1869). 
G. similis G. princei, sed gutture cinereo nec albo distinguenda. 
Тнів species was discovered by Du Chaillu in Gaboon, during his celebrated exploration of Tropical 
West Africa. It has never been met with since, and Seebohm states, in the “Catalogue of Birds ’ 
(v. p. 165), that the type-specimen in the Philadelphia Academy's Museum appears to have been 
mislaid. The skulking habits of some of these Geocichle render them very difficult to procure in 
the tropical forests which they inhabit; and, asa case in point, I may mention Geocichla crossleyi, 
a perfectly distinct species discovered in the Cameroons Mountains by the late Mr. A. Crossley in 
1871, and never since obtained, though Professor Reichenow and Professor Sjóstedt have done 
their utmost to procure specimens, and the large collections made by the German travellers have 
never yielded a single example. 
We may therefore state that 6. compsonota is a species of which we should like to see another 
specimen, since Cassin's original description is somewhat meagre, as Seebohm justly remarks. Тһе 
latter gentleman thinks that it will be found to be allied to the equally rare G. crossleyi, but he 
places it near G. princei in the ‘ Catalogue.'
