There appears to 'be some doubt as to whether the species 

 S. brunheicaudalis Sclater, occurs in British Guiana, as when the 

 late Dr. Sclater wrote Vol. xv. of the ' Catalogue of Birds in 

 the British Museum ' there was but one specimen of that sj)ecies 

 from Ecuador, and that is certainly not the same as the Guiana 

 bird. I have therefore described the latter as a distinct species.
