Remarks.— But a cursory examination of the material assembled 
for the present study was necessary to demonstrate that there 
were three types represented therein, separable with a fair degree 
of ease and certainty. The specimens of plesius disposed of, 
there remained the two dark colored coastal races, with the at- 
tendant problem as to which of them should bear the name paludi- 
cola. By the courtesy of the United States National Museum, 
through Dr. C. W. Richmond, I was enabled to examine Baird’s 
type of Cistothorus palustris, var. paludicola, indispensable for a 
proper understanding of the question. There are also at hand, 
received from the collection of the above mentioned institution 
and from those of the Oregon State University and the Oregon 
State Fish and Game Commission, some additional skins from the 
coast of Oregon and Washington, in the same general region as 
the type locality of paludicola. 
While there is no doubt as to the distinctness of the two dark- 
colored coastal races here recognized, for the differences are trench- 
ant enough to be appreciable at a glance, the nature of the type of 
paludicola makes it difficult to decide as to which of the two is the 
unnamed form. The type specimen of paludicola is a non-sexed 
bird taken October 31, a date that renders it possible at least that 
it was a winter visitant at the point of capture (Shoalwater Bay, 
southern Washington), and not representative of the breeding 
bird of that region. In size it is somewhat larger than the average
