Wren, Common in the large fresh-water marshes during 
summer, where it breeds during the latter part of May. 
22. Cistothorus palustris, Cab. — Short-hilled Marsh 
Wren, Rather more common than the preceding. Fre- 
quents the same localities. It is exceedingly difficult to 
procure, on account of its lying very closely when hunted. 
MOTACILLIDiE, — The Wagtails. 
23. Anthus Ludovicianus, Light. — Tit-larh, Abun- 
dant spring and autumn migrant along the coast. I am

Thrushes. 
SYLVICOLID^, — The Wood-Warblers. 
24. Mniotilta varia, Yieill. — Blach and White Creep-

Breeds. 
25. Parula Americana, Bon. — Blue Yellow-hacked 
Warhler, Summer resident. This beautiful little Warbler

particular abundance. Found generally in oak woods. 
Arrives about the second week in May ; leaves in the mid-

it breeds quite commonly in certain localities. 
26. Geothlypis trichas, Cab. — Maryland Yellow-
