250 Trans. Acad. Sci. of St. Louis. 
taken on the lower Blue River on May 6, 1914, and another seen 
in the same place on May 8, 1914. A specimen has been reported 
from Platte County and another from a point about forty miles 
to the west. No other datum is at hand. 
ARQUATELLA MARITIMA MARITIMA (Brunnich). Purple Sand- 
piper. 
Accidental. 
The Purple Sandpiper is listed on the strength of the speci- 
men taken near here by Dr. Hoy in 1854 (19th Annual Report 
Smithsonian for 1864). 
PISOBIA MACULATA (Vieillot). Pectoral Sandpiper. 
Very common migrant. 
The Pectoral Sandpiper arrives from the 12th to 18th of 
April, in some years much earlier (March 15, 1905; March 30, 
1911; March 24, 1916), and is present until the last of May. 
It is seen sometimes as early as the middle of August, on the 
return flight from the north, and the last birds have not passed 
until early November. It is often observed in very large flocks 
along the Missouri bottoms about suitable shallow feeding places. 
During the passing of the bulk of the flight, usually the last 
week in April, small flocks have been seen about the lagoon in 
Swope Park. 
PIsoBIA FUSCICOLLIS (Vieillot). White-rumped Sandpiper. 
Not uncommon migrant. 
This bird has been frequently observed on the river and a few 
times on ponds. All the available dates of its appearance are in 
the first week in May. The migration periods have not been 
worked out. 
PISOBIA BAIRDI (Coues). Baird’s Sandpiper. 
Not uncommon migrant. 
The Baird’s Sandpiper is present from the middle of April 
to the first of June and from the last of August to nearly the 
middle of October (October 13, 1893). It is usually found with 
other small sandpipers. A recent record is one specimen taken 
on the Missouri River, near Courtney, by A. F. Frazier, on 
April 17, 1914.
