Owing to the former incompleteness of bird material from the 

 northwest, the relationships of some western forms to their eastern 

 allies has remained a vexed question. The seines in my possession 

 have, in some instances, supplied this deficiency and seem to justify 

 certain changes in nomenclature. Of these may be mentioned, 1. 

 Corvus eaurinus merged with the northwest form of C. amerieanus, 

 and conjointly separated from eastern C. amerieanus under the name 

 Corvits amerieanus eaurinus. 2. The relegation of Melospiza lincolni 

 striata to synonymy. 3. The elevation of the northwest Warbling 

 Vireo to its former rank of Vireo gilvus swainsonii. 4. Sylvaniapus- 

 illa pileolata made synonymous with Sylvania pusilla. 5. The possi- 

 bility that Tardus aonalaschkee and Tardus aonalaschkae jta/lasii are 

 specifically distinct. 



The localities where collections were made number fourteen. In 

 order of sequence they may thus be separately described : 



1. Tacoma, Washington, March 4-28. 



2. Nisqually Flats, Washington, March 29- April 22. 



The situation of Tacoma on Puget Sound is well known, that of 

 Nisqually Flats, fourteen miles southwest of it, at the mouth of the 

 river of the same name, though less known, is far more historic ground, 

 being part of the territory surveyed by the well known naturalists 

 of the Pacific Railroad Expedition of 1853-55. The country in 

 this region is moderately hilly and densely forest-clad, save where 

 intervening level, park-like areas indicate by their stunted vegeta- 

 tion the presence of vast beds of glacial gravel. The shore lines 

 of Puget Sound present an almost unbroken frontage of abrupt, 

 fir-clad slopes from 100 to 500 feet high ; many rocky islands, some 

 of goodly size, intervene and the uplands are well interspersed with
