A Draft Arrangement of the Genus Thamnophilus, Vieilloi. 

 By Philip Lutley Sclater, M.A., F.Z.S. 



The bush-shrikes of South America, forming the genus 

 Thamnophilus of Vieillot, have been much neglected by mo- 

 dern ornithologists, and are at present in a sad state of con- 

 fusion. Mr George Gray, in his Genera of Birds, gives a list 

 of more than fifty species of the genus, while the Prince 

 Charles Bonaparte in his Conspectus, under the three heads 

 Cymbilaimus , Thamnophilus, and Dysithamnus (which to- 

 gether correspond to Mr Gray's Thamnophilus), reduces the 

 number to sixteen. Excluding the four or five Dysithamni, 

 which I think are fairly entitled to generic separation, I am 

 acquainted with about thirty-six distinct members of the genus 

 Thamnophilus. Three others, which I have not yet seen, 

 raise the total number included in the following list to thirty- 

 nine. These I believe to be all truly existing species ; others 

 which have been placed by different authors in the genus, but 

 which I do not believe to be valid species, are the following :
