According to my views of the relationships of the Long-billed 

 Marsh Wrens, the various forms of the subgenus Telmatodytes 

 should be arranged as follows. 



Cistothorus palustris palustris (Wils.). Salt marshes of Atlantic coast 

 from Connecticut to Virginia, in winter to South Carolina. 



Cistothorus palnstris dissaeptus Bangs. Fresh-water marshes of eastern 

 United States and parts of Canada, breeding from Middle States to Massa- 

 chusetts, Ontario and southern Manitoba, wintering from Massachusetts 

 southward, probably to eastern Mexico. 



Cistothorus palustris paludicpla Baird. Pacific coast region of United 

 States and southern British Columbia. Probably nearly non-migratory. 



Cistothorus palustris plesius Oberholser. Western United States and 

 interior British Columbia from the Sierra Nevada and Cascade Mts. to 

 the Rocky Mts., south to southern Mexico. Probably only migratory at 



TAuk 

 LOct.
