M[yrmeciza] l[ongipes] griseipectus Hellmayr, Novit. Zool. XIII. 1906. 



P- 33- 



Eye bright chestnut ; bill black ; feet pinkish white. 



This species was not noted below Caicara, but was observed on 

 the upper river as far as I extended my explorations. It inhabits the 

 thick forest, and while not rare it is more often heard than seen. It 

 has a high flute-like whistle that is very difficult to trace. Birds may 

 be very near, concealed in the thick underbrush, but as they walk 

 rapidly away from one, the call notes seem to come from half a dozen 

 different directions. I have never seen them anywhere except on the 

 ground where they walk and run easily and gracefully over the fallen 

 (leaves, and when flushed fly but a short distance and again drop to 

 the ground. 



In the American Museum collection is a series collected by 

 Klages at Suapure and Maripa on the Caura River.
