May and is found abont muddy pools and flats near the Lake until the 

 5th of June. Returning iu winter dress during September it remains 

 well into October. At tliis season it is generally found in small par- 

 ties, while in spring tlio flocks often contain hundreds of individuals. 



220. T. eanutus Lln-n. Kxot. This is another of the so-called 

 "maritime species" which regularly visits its breeding grounds by 

 way of the "Great Lakes," as well as along the coast. 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 aw.iy from the vicinity of the Lake shore, where it is generally 

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



Genus Calidris Cuv. 



221. C. arenaria Linn. Sandkulixg. Abundant migrant along 

 the Lake shore. Arrives in full breeding plumage — which varies 

 greatly with individuals — about the 20th of May, and is found in 

 flocks, numbering from five to seventy-five, along the shore, until 

 June 10th. Keturns the first of August, still wearing its breeding 

 dress, which is changed the last of the month for the duller garb of 

 winter. Departs for the south by the 20th of October. This species, 

 with yE. mdoda, is found almost exclusively along the bare sandy 

 beach, where it would seem an impossibility for it to obtain a living. 



Genus Liuiosa Bnss. 



222. L. fedoa (it»?t.). Maublkd Godwit. Eather common mi- 

 grant. April 15th to May 15th, and September 10th to October 20th. 



223. L. hudsonica Sw. Hudsonian Godwit. Not very rare 

 during the migrations. April loth to May 10th, and September to the 

 first of October. More common along the water courses in the west- 

 ern part of the state. 



Genus Totanus Bech. 



224. T. semipalmatus Temm. Willet. Rare summer resident 

 in the marshes and on wet prairies. Arrives the last of April and 

 first of May. Departs by the first of October. 



225. T. melanoleucus Gmel. Grkater Ykllow-legs. A com- 

 mon migrant and regular summer resident. Breeds. Arrives about 

 the middle of April, the larger portion passing north early in May. 

 Returns September first and remains until the last of October. In June, 

 1875, I found several pairs of these birds about the Calumet Marshes, 

 where, from their actions, I was certain they were breeding, but was 

 not fortunate enough to find their nests. The 10th of June, 1876, Mr. 

 Rice obsei'ved a pair about a prairie slough near Evanston. A few 

 days later a set of four eggs were brought him from a similar situa-
