Hub. Pacific coast United States. 



In comparing a series of Marsh Wrens of eastern Xorth America 

 with western, I find that they differ appreciably in certain character- 

 istics, which may perhaps be expressed by the following diagnoses :- — 



Var. palustris. — Bill lengthened, equal to tarsus. Tail coverts above and 

 below either perfectly plain, or with very obsolete bands, reduced to 

 obscure spots beneath. Bands on tail broken ; scarcely appreciable on 

 the middle feathers. 



Var. paludicola. — Bill shorter than tarsus. Tail coverts distinctly banded 

 all across. Bands on tail quite distinct ; appreciable on the central 

 feathers. 



How far these differences in size of bill, etc., will be found persist- 

 ent through larger series of specimens, I am unable to say. 



I am unable at pi^esent to say to which variety the Mexican bird 

 (Sclater, P. Z. S. 1856, 290), and the Guatemalan (Sclater & Salvin, 

 Ibis, 1859, 8) belong.

 2.00; graduation, .45; exposed portion of 1st primary, .63, of 2d, 1.25; of 

 longest (measured from exposed base of 1st primary), 1.50 ; length of bill 

 from forehead, .60, from nostril, .38, along gape, .70 ; tarsus, .78 ; middle toe 

 and claw, .61 ; claw alone, .20 ; hind toe and claw, .50 ; claw alone, .26.
