previously in Aroentina near Concepcion, Tucuman, on March 4,<br />

1918," but the present record is the farthest sonth at which the<br />

spotted sandpiper has been Imown. (The statement in El Hornero<br />

that my specimen was secured at Cape San Antonio was due to a<br />

misunderstanding on the part of Doctor Dabbene.)<br />

TRINGA SOLITARIA CINNAMOMEA (Brewster)<br />

Totamis solitarius clnnamomeus Brewster, Auk, vol. 7, 1890, p. 377. (San<br />

Jose del Cabo, Lower California.)<br />

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 />

December 3, when a male was killed on the Rio Negro, near General<br />

Roca, Rio Negro, where it was found amid scattered willows on<br />

a muddy shore from which water had recently receded. Apparently<br />

this is the farthest south from which the species has been recorded.<br />

At Lazcano, Rocha, from February 2 to 8, solitary sandpipers were<br />

in migration in small numbers and were traveling northeastward<br />

along the Rio Cebollati toward the coast. A female was taken Feb-<br />

ruary 7. One was recorded at Rio Negro, Uruguay, on February 17,<br />

and one was seen at a road<strong>si</strong>de pool near General Campos, in Entre<br />

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

Buenos Aires, March 2. During the night of April 5 at Tucuman,<br />

Tucuman, the call of this species was heard frequently among the<br />

notes from the great flight of waders that passed northward over<br />

the city. At this southern end of their range the solitary sandpiper<br />

frequents the margins of shallow pools as in the north, often in<br />

localities unsought by other waders. I found it far from common.<br />
