Genus TRINCrA Linnaeus, 1758. 

 Tringa canutus Linnaeus. Knot. 



Tringa canutus LINN^US, S. N., ed. 10, I, 1758, 149. 

 Tringa cinerea BRUNN., Orn. Bor., 1764, 53. 



Popular synonyms: ROBIN SNIPE. RED-BREAST. GRAY-BACK. KNOT 

 SANDPIPER. 



A rare fall visitant. The only records I have of the taking of 

 this species within our limits, are as follows: One specimen 

 taken August 24, 1896 and four taken August 21, 1897, at Mil- 

 lers, Indiana ; and eight taken by Mr. Charles Brandler at Wolf 

 Lake, Indiana, in August, 1897. For some time, I have seen, 

 them each year throughout the month of August at Millers, 

 Indiana. Mr. E. W. Nelson says:* "It is not a common but a 

 regular migrant, passing north during May. It returns early in 

 September and remains until October. I have never observed it 

 away from the vicinity of the Lake shore, where it is generally 

 found in company with one or two others of the same family." 



The range of the Knot covers the northern hemispheres, 

 though it occasionally visits the southern hemisphere during its 

 migrations. 



Genus AEQUATELLA Baird, 1858. 

 Arqnatella maritima (Briinn.). Purple Sandpiper. 



Tringa maritima BRUNN., Orn. Bor., 1764, 54. 



Arquatella maritima COUES, Proc. Acad. Nat. Sci. Philadelphia, 1861, 

 183. 



Popular synonym : ROCK SNIPE. 



A very rare migrant. In its migrations, it probably will ap- 

 pear in our vicinity at about the same time as the Knot. The only 

 record I have of the appearance of this bird within our limits, is 

 that of Mr. E. W. Nelson ,who says if "A fine adult male ob- 

 tained on the Lake shore, near Chicago, November 7th, 1871, is 

 in the collection of Dr. J. W. Velie. When first seen it was in 

 company with a flock of sanderlings. This is the only instance 

 of the occurrence of this species of which I have learned." 



Its range includes the northeastern portions of North Amer- 

 ica, breeding very far north and migrating in winter to the mid- 

 dle states, the Great Lakes and the larger rivers of the Mississippi 

 Valley.

Actodromas maculata (Vieillot). Pectoral Sandpiper.
