178. Calidris arenaria, ILLIG. Sanderling, "Shore- 

 Bird," " Beach-Bird." Abundant on the sandy shores and 

 beaches during the migrations. 



179. Tringa canutus, LINN. Knot, "Gray-back." 

 Common spring and autumn migrant. 



180. Arquatella maritima, BAIRD. Purple Sand- 

 piper, "Rock Snipe." Never very common. Found on 

 the coast during spring and autumn. 



181. Ancylocheilus subarquatus, KAUP. Curlew 

 Sandpiper. Accidental, or very rare. A few specimens, 

 taken on our coast. 



182. Pelidna Americana, COUES. American Dunlin, 

 " Red-back." Abundant spring and autumn migrant. Have 

 taken it late in November. I do not think it winters. 



On June 18, 1868, I saw and shot several specimens of 

 this Sandpiper about the fresh-water ponds on Ipswich 

 beach; they were fat, and, upon dissecting, the females, 

 did not exhibit any signs of breeding ; they were evidently 

 the young of the preceding year. 



183. Actodromas maculata, CASS. Pectoral Sand- 

 piper, "Jacksnipe," "Grass- Bird," "Fat-Bird." Common 

 during the migrations. Frequents the marshes. 



184. Actodromas minutilla, COUES. Least Sand- 

 piper, " Peep." Abundant during the migrations. 



185. Actodromas Bonapartii, CASS. Bonapartds 

 Sandpiper, " White -rumped Sandpiper," "Grass -Bird." 

 Abundant during the migrations. Frequents the marshes. 



1 86. Ereunetes pusillus, CASS. Semipalmated Sand- 

 piper, "Peep." Abundant during the migrations. June 18, 

 1868, they were found in company with P. Americana, at 

 Ipswich, and were in the same condition. 



187. Micropalama him ant opus, BAIRD. Stilt 

 Sandpiper. Very rare. A single specimen captured in au- 

 tumn by Mr. W. Brewster, at Rye Beach, New Hampshire.* 



* Mr. Brewster informs me that he took another at the same place- 

 in the last week in August, 1 869.
