308. Geothlypis agilis. CONNECTICUT WARBLER. A very 

 rare spring but not uncommon fall migrant ; sometimes abundant 

 in autumn in the vicinity of Cambridge. Probably more common 

 in other parts of the State at that season than is generally sup- 

 posed. Spring records are : Readville, May 24, 1883 (Maynard, 

 Journ. Boston Zool. Soc., II, 1883, 43) ; Ashland, five specimens, 

 spring, 1883 and 1884 (Castle, Orn. and Ool., IX, 1884, 75). Erro- 

 neous spring records for New England are New Haven, Conn. 

 (Woolsey, Bull. Nutt. Orn. Club, V, 1880, 117); Bangor, Maine 

 (Merrill, Bull. Nutt. Orn. Club, II, 1877 corrected, Merrill, 

 Auk, III, 1886, 413). 



*309. Geothlypis Philadelphia. MOURNING WARBLER.

 a summer resident, breeding numerously, in the higher portions 

 of Berkshire County (Brewster, Auk, I, 1884, 14, 15). 



*310. Geothlypis trichas. MARYLAND YELLOW-THROAT. 

 Abundant summer resident. 



*311. Icteria virens. YELLOW-BREASTED CHAT. Rare sum-
