66 Proceedings of the 



upon by my horse. It was not seen on later occasions and 

 was, in all likelihood, a migrating bird. 



21. Pisobia maculata (Vieillot) — Pectoral Sandpiper, 



Keported by R. H. Wolcott as present in June 1906. 



22. Piwbia fiiscicollis (Vieillot)— White-rumped Sandpiper. 



This sandpiper was noted on August 21, 1911, and 

 again rather commonly from May 20 to 31, 1912, on both 

 the Loup and Dismal rivers. A flock of twenty-five 

 White-rumped and Baird Sandpipers was seen at the lat- 

 ter place on May 26, while single individuals of the pres- 

 ent species were noted in the Loup valley as late as June 

 5 and June 19. 



23. Pisobia bairdi (Coues) — Baird Sandpiper. 



I saw a Baird Sandpiper on August 21, 1911, and dur- 

 ing 1912 I found flocks of the birds on the Loup river 

 on May 21, 31 and June 1. On May 26 they were seen on 

 the Dismal river in company with the preceding species. 



24. Pisobia minutilla (Vieillot) — Least Sandpiper. 



On July 12, 1912, I saw a pair of Least Sandpipers in 

 a very favorable situation for their breeding. They were 

 at the time out in the middle of the stream on a sandbar 

 and were quite wary. Since I could not conceal myself 

 while approaching them, I was unable to get within range 

 before they became sufficiently alarmed to fly. These birds 

 were not migrants, I believe, although they may have 

 been merely summer residents. 



25. Ereunetes pusillus (Linnaeus) — Semipalmated Sandpiper. 



The Semipalmated Sandpiper was noted very sparingly 

 on August 20, 1911, and on May 21 and 25, 1912, on the 

 Middle Loup and was seen in small numbers on the Dis- 

 mal river on May 26 of the latter year. It probably mi- 

 grates regularly at Halsey in greater or less numbers. 



26. Totanus mclanoleucus (Gmelin) — Greater Yellow-legs. 



On September 20, 1911, there was a single Greater Yel- 

 low-legs present on the sandbars in the river near the sta- 

 tion. It was not noted on other occasions. 



27. Hclodromas solifarius (Wilson) — Solitary Sandpiper. 



I noted the Solitary Sandpiper on September 1 and 2, 

 1911, and on July 12 and 17 and September 6, 1912, a
