152 SMITHSONIAN MISCELLANEOUS COLLECTIONS __ [VOL. 48 
broader bills with a more extended nasal operculum, and vary some 
in other proportions, but the differences do not seem sufficiently 
marked to render advisable at present a further subdivision of the 
group. 
Of the species now to be referred to this genus, one, Trichophorus 
gularis (Horsfield),* requires to be renamed, since its present title 
is preoccupied by Turdus gularis Latham? which is Cinclus merula 
(SCHAFFER) (== aquaticus Auct.) ; and it may be known as Tricho- 
phorus xanthizurus. 
A list of the species of this genus follows: 
Trichophorus chloronotus Cassin. 
Trichophorus calurus Cassin. 
Trichophorus verreauxi verreauxt (Sharpe). 
Trichophorus verreauxi ndussumensis (Reichenow). 
Trichophorus flaveolus Gould. 
Trichophorus frater (Sharpe). 
Trichophorus burmanicus (Oates). 
Trichophorus griseiceps (Hume). 
Trichophorus salangae (Sharpe). 
Trichophorus xanthizurus Oberholser (= gularis Horsfield, nec Latham). 
Trichophorus tephrogenys Jardine and Selby (= gutturalis Bonaparte). 
Trichophorus sordidus (Richmond). 
Trichophorus henrict (Oustalet). 
Trichophorus pallidus (Swinhoe). 
Trichophorus ruficrissus (Sharpe).
