BIRDS OF THE CAMBRIDGE REGION. l6l 



low level, laying bare a considerable portion of the sandy bottom of Cambridge 

 Nook. Here, on August 4 of the year just mentioned, I found a flock containing 

 upwards of one hundred Semipalmatcd Sandpipers besides a few Least Sand- 

 pipers and about a dozen Ring-necked Plover. 



Although I have few definite notes of the occurrence of the Semipalmatcd 

 Sandpiper within the past few years, there can be little question that it con-

 it frequents sandy beaches and is still common, at its seasons of migration, 

 especially in early autumn.

HUDSONIAN GODWIT. 



Exceedingly rare transient visitor in autumn. 



Mr. Outram Bangs tells me that he saw a Hudsonian Godwit near the 

 head of tide-water in Charles River in August or September about 1875. It 

 was feeding, not far from the Watertown Arsenal, on a muddy island formerly 

 much frequented by Yellow-legs, Ring-necked Plover, and Least and Semipal- 

 matcd Sandpipers. This is the only instance known to me of the occurrence 

 of the Hudsonian Godwit in the Cambridge Region. There is a record of a
