f*. Grayer. Hab. Interior districts, east to Mississippi Valley (Minnesota,*: 
Illinois, ete.), south over table-lands of Mexico. 
721. T. aédon aztecus Barrp. Aztec Wren, 
(91.) Page 556, after C. palustris paludicola: 
725b. Cistothorus palustris marianze (Scorr). Marian'’s Marsh Wren 
Somewhat like C. palustris, but smaller and much more olivaceous in color, 
with rump, tail-coverts, and flanks barred with dusky; superciliary stripe much 
less distinct (broken by conspicuous black streaking), the breast sometimes 
barred or speckled with dusky. Hab. Salt marshes of western Florida (Tarpon 
Springs, etc.). 
725¢. Cistothorus palustris griseus Brewst. Worthington’s Marsh Wren? 
“Of the size and proportions of C. marian, but with less black above and 
no distinct dark markings on the under tail-coverts, flanks, sides, or breast. 
General coloring very much paler and grayer than in either mariane or palustris. 
Bill colored as in C. mariane.” Hab. Coast of South Carolina to northern 
Florida (Anastasia Island). 
(92.) Page 559, after S. carolinensis : 
727b. Sitta carolinensis atkinsi Scorr. Florida White-breasted Nuthatch? 
Smaller than S. carolinensis. “Bill relatively much longer and slenderer. 
Light markings of tipping of the coverts and quills of the wings decidedly 
narrower. A little less white in the tail. In the female bird the black of the 
top of the head and nape is pronounced, and it is difficult to distinguish the sexes 
easily, and in some cases impossible, by the color of these parts.” Hab. Florida.

with scarcely more than a trace of buffy tinge. Hab. San Pedro Mountains, 
Lower California.
