inner webs o£ primary and secondary qnills dark brown, diminish- 

 ing in extent towards the inner quills where it is restricted to the

The male described was collected at Bartica in 1911. 



There is a specimen from the Rio Negro, collected by Natterer, 

 in the British Museum which was said by the late Dr. P. L. 

 Sclater to be S. inornata Pelzeln. This bird appears to me to be 

 quite different from S. guianensis and is worthy at least of sub- 

 specific rank. I would suggest, therefore, that it be called 

 Synallaxis guianensis inornata.
