previously in Aroentina near Concepcion, Tucuman, on March 4, 

 1918," but the present record is the farthest sonth at which the 

 spotted sandpiper has been Imown. (The statement in El Hornero 

 that my specimen was secured at Cape San Antonio was due to a 

 misunderstanding on the part of Doctor Dabbene.) 



TRINGA SOLITARIA CINNAMOMEA (Brewster) 



Totamis solitarius clnnamomeus Brewster, Auk, vol. 7, 1890, p. 377. (San 

 Jose del Cabo, Lower California.) 



As has been said in the account under Totanus melanoleucus, the 

 solitary sandpiper belongs with the wood sandpiper in Trlnga, a 

 genus of tringine sandpipers characterized by a tAvo-notched meta- 

 sternum, with the nasal groove extended for two-thirds or less of 

 the maxilla. 



The solitary sandpiper in its southward migration reached For- 

 mosa, Formosa, on the Rio Paraguay, on August 23, 1920, when 

 three were found on overflowed ground along a slough tributary to 

 the Paraguay. The birds were silent and walked so quietly along 

 the borders of the pools, often where overhung by brush or grass, that 

 they might easily have been overlooked. An adult female that I 

 shot was thin in flesh, and from other indications I was certain that 

 these birds had just arrived. At Kilometer 80, west of Puerto Pi- 

 nasco, Paragua}^, solitary sandpipers passed southward, stopping 

 occasionally at the lagoons, from September 6 to 21, and on Septem- 

 ber 24 and 25 a number were seen at Laguna Wall at a point 200 

 kilometers west of the river. The species was not recorded during 

 spring and summer on the pampas, and was not seen again until 

 December 3, when a male was killed on the Rio Negro, near Gen- 

 eral Roca, Rio Negro, where it was found amid scattered willows on 

 a muddy shore from which water had recently receded. Apparently 

 this is the farthest south from which the species has been recorded. 

 At Lazcano, Rocha, from February 2 to 8, solitary sandpipers were 

 in migration in small numbers and were traveling northeastward 

 along the Rio Cebollati toward the coast. A female was taken Feb- 

 ruary 7. One was recorded at Rio Negro, Uruguay, on February 17, 

 and one was seen at a roadside pool near General Campos, in Entre 

 Rios, Argentina, on February 23. Another was noted at 2.5 de Mayo, 

 Buenos Aires, March 2. During the night of April 5 at Tucuman, 

 Tucuman, the call of this species was heard frequently among the 

 notes from the great flight of waders that passed northward over 

 the city. At this southern end of their range the solitary sandpiper 

 frequents the margins of shallow pools as in the north, often in 

 localities unsought by other waders. I found it far from common.
