200 THE AMERICAN MIDLAND NATURALIST. 
On June 28, 1918, Mahlon Palmer and I identified five indi- 
viduals at Willow Pond, and on June 29 I identified two at 
the same locality. , 
55. Pisobia fusicollis (Vieill.) White-rumped Sandpiper. 
According to Webster and J. R. Waller this species was a 
rather common migrant near Rockford and Charles City. The 
reference to it as a “rather common migrant, appearing the 
last of May about the quiet pools near watercourses” by 
Keyes and Williams (Bds. of Iowa, 1889, 122) is probably 
from Williams’ observations in Floyd County. I have a very 
questionable record for May 12, 1917; one bird seen on the 
bank of Lime Creek, near Rockford. 
56. Pisobia minutilla (Vieill.) Least Sandpiper. A com- 
mon migrant in Floyd and adjoining counties. In both spring 
and late summer it is abundant along the bayous of the Cedar 
north and west of Charles City. It associates with both the~ 
Semipalmated Sandpiper and the Spotted Sandpiper. The 
spring migration begins about the first of May and lasts 
throughout the month. The birds reappear in late July or 
early August and may be seen well through September. 
57. Hreunetes pusillus (Linn.) Semipalmated Sandpiper. 
A rather uncommon species associated with the foregoing in 
its migrations. I saw five specimens at Willow Pond on May 
23, 1918. It is usually to be seen along the Cedar River. 
58. Limosa fedoa (Linn.) Marbled Godwit. Rare migrant 
in Floyd County. (Webster.) Mr. J. W. Preston found it 
breeding at Clear Lake, in Cerro Gordo county. (Cooke, Bd. 
Migr. in Miss. Val., 1884-5, 94.) I have a questionable iden- 
tification made at Hackberry Grove, Cerro Gordo county, on 
June 6, 1917. 
59. Totanus melanoleucus (Gmel.) Greater Yellow-legs. 
A fairly common migrant, being seen mostly in slougs and 
along the streams. It appears in the spring in late April. On 
June 12, 1917, I saw four individuals on Flood Creek. The 
autumn migration is irregular, beginning in mid-September 
_and lasting into-October. 
60. Totanus flavipes (Gmel.) Yellow-legs. More common
