Wren. Common in the large fresh-water marshes during 
summer, where it breeds during the latter part of May. 
22. Cistothorus palustris, Cas. — Short-billed 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. 
MOTACILLID, — THe Waeraits. 
23. Anthus Ludovicianus, Licut. — 7%t-lark. Abun- 
dant spring aud autumn migrant along the coast. I am 
informed by my friend, Mr. William Brewster, that it is 
also abundant on the Fresh Pond marshes, near Cam- 
bridge. It has the habit of jerking its tail like the Water 
Thrushes. 
SYLVICOLID, — THE Woop-War3BLeErs. 
24. Mniotilta varia, Vieitu. — Black and White Creep- 
er. Common summer resident. Abundant during the mi- 
grations. Found in the woods everywhere. Arrives the 
Jast week in April; leaves the latter part of September. 
Breeds. 
25. Parula Americana, Bon. — Blue Yellow-backed 
Warbler. Summer resident. This beautiful little Warbler 
seems to be a somewhat irregular visitor while migrating. 
During the spring of 1867 it was very abundant ; in 1868 
I could find but two or three, although I searched dili- 
gently for it; while the season of 1869 brought it in 
particular abundance. Found generally in oak woods. 
Arrives about the second week in May ; leaves in the mid- 
dle of September. Mr. William Brewster informs me that 
it breeds quite commonly in certain localities. 
26: Geothlypis trichas,; Cas.— Maryland Yellow.
