Wren. Common in the large fresh-water marshes during 

 summer, where it breeds during the latter part of May. 



22. Cistothorus Stellaris, 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. 



MOTACILLID.E, — The Wagtails. 



23. Anthus Ludovicianus, LicHT. — Tit-larl: Abim- 

 dant spring and 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 

 Thrashes. 



SYLVICOLID.E, — The Wood- Warblers. 



24. Mniotilta varia, Vieill. — Black and White Creep- 

 er. Common summer resident. Abundant during the mi- 

 gi-ations. Found in the woods everywhere. Arrives the 

 last week in April ; leaves the latter part of September. 

 Breeds. 



25. Farula Americana, Box. — Blue Yclloic-haclrd 

 Warbler. Summer resident. This beautiful little Warbler 

 seems to be a somewhat in-egular visitor while migrating. 

 During the spring of 18G7 it was very abundant; in 1808 

 I could find but two or three, altiiough I searched dili- 

 gently for it ; while the season of 18G9 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.
