GALEOSCOPTES, Cabanis. 

 Galeoscoptes, Cabanis, Mus. Hein. 1, 1850, 82. (Type Muscicapa carolinensis, L.) 



Bill shorter than the head, rather broad at base. Eictal bristles moderately 

 developed, reaching to the n'ostrils. Wings a little shorter than the tail, 

 rounded ; secondaries well developed ; 4th and 5th quills longest ; 3d and 6th 

 little shorter; 1st and 9th about equal, and about the length of secondaries ; 

 1st quill more than half the second, about half the 3d. Tail graduated ; 

 lateral feather about .70 shorter than the middle. Tarsi longer than middle 

 toe and claw by about an additional half claw ; scutellate anteriorly, more or 

 less distinctly in different specimens ; scutellse about seven. 



The conspicuous naked membranous border round the eye of some Thrushes, 

 with the bare space behind it, not appreciable. 



I find little difference in form between the single species of Galeo- 

 SGoptes and Mimus polyglottus, beyond the less degree of definition 

 of the tarsal plates; and but for the difference in coloration (uniform 

 plumbeous instead of gray above and white beneath), would hardly 

 be inclined to distinguish the two generically.
