Hydrolegus silvestrianus of Bertoni as a synonym of the 
present species. 
[This strange bird is resident and not uncommon in this 
district. It can only be met with along the forest streams. 
Its food consists exclusively of the water insects and possibly 
spawn of fish and frogs. It invariably stands on the stones 
in the water, and at times even when the water is over the 
top.— W. F.]

The examples from Paraguay agree in every respect with 
those in the National Collection from Brazil, whence the 
species was described. I agree, therefore, with Dr. Ihering 
and Mr. C. W. Richmond in considering S. (Barnesia ) curu¬ 
ruvi of Bertoni as a synonym of this species. 
[I have met with this species feeding on the ground in 
the forests at Sapucay.— W. F.~\
