Remarks.

—

In structure

and

sizethe presentspeciesagreesfairly wellwith Dryonastesperspicillatus (Dryonastes^{as at}present constituted^isnotavery

homogeneous

genus), but not in color.

The

black

of Dryonastes grahamionly^{differsin detail}fromthatofDryonastesperspicillatus,butthe whiteonthe ear-coverts

and

sides ofneck

and

_gray

plumage

^oftheformer

make

itvery^distinct

and

quite unlike
