TFre?i. 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, Light. — Tit-larh. Abun-

 Breeds. 



25. Parula Americana, Box. — Blue Yelloiv-had-ed 

 Wai'hler. Summer resident. This beautiful little Warbler 

 seems to be a somewhat irregular visitor while migi'ating.

 it breeds quite commonl}" in certain localities.
