insist upon the importance it would be to science, if all persons 
who may figure or describe any species, would not only mark the

“ Crown of the head bluish-black; shoulders and back ferrugi- 
nous brown, obscurely marked with narrow transverse lines of black, 
which bound the edges of each feather. Tail uniform pale rufous

chest, flanks and under tail-coyers light ferruginons, barred with
