As has been said in the account under Totanus melanoleucus, the<br />

solitary sandpiper belongs with the wood sandpiper in Trlnga, a<br />

genus of tringine sandpipers characterized by a tAvo-notched meta-<br />

sternum, with the nasal groove extended for two-thirds or less of<br />

the maxilla.<br />

The solitary sandpiper in its southward migration reached Formosa,<br />

Formosa, on the Rio Paraguay, on August 23, 1920, when<br />

three were found on overflowed ground along a slough tributary to<br />

the Paraguay. The birds were <strong>si</strong>lent and walked so quietly along<br />

the borders of the pools, often where overhung by brush or grass, that<br />

they might ea<strong>si</strong>ly have been overlooked. An adult female that I<br />

shot was thin in flesh, and from other indications I was certain that<br />

these birds had just arrived. At Kilometer 80, west of Puerto Pi-<br />

nasco, Paragua}^, solitary sandpipers passed southward, stopping<br />

occa<strong>si</strong>onally at the lagoons, from September 6 to 21, and on September<br />

24 and 25 a number were seen at Laguna Wall at a point 200<br />

kilometers west of the river. The species was not recorded during<br />

spring and summer on the pampas, and was not seen again until<br />

Rios, Argentina, on February 23. Another was noted at 2.5 de Mayo,<br />
