124 Mr. J. Graham Kerr on the Avifauna 



[This Swallow was not included in our work, but must be 

 now added to the Argentine avifauna. — P. L. S.] 



12. Tachycineta leucorrhoa. {Op. cit. i. p. 30.) 

 (No. 186, S •) Fortin Page. September 2nd, 1890. 



13. EUPHONIA CHLOROTICA. (Oj9. Clt. i. p. 37.) 



(No. 18, S ■) Puerto Bermejo. February 28th, 1891. 

 In the forests bordering the Rio Paraguay. 



14. Tanagra sayaca. {Op. cit. p. 39.) 



(No. 74, S; 106, ? .) Fortin Nueve. April 24th, 1890. 



Common during the winter months ; generally feeding 

 in company with other Tanagers and Finches among the 

 terminal twigs of the larger trees, and also amongst the 

 bushes. About the beginning of September it began to de- 

 crease greatly in numbers, and a little later almost entirely 

 disappeared. 



[The specimens brought home appear to belong to T. cya- 

 noptera rather than to T. sayaca. But after what Mr. Allen 

 savs about the series collected by H. H. Smith in Matto Grosso 

 (Bull. Am. Mus. N. H. iii. p. 354), I can hardly maintain the 

 supposed distinctness of these two forms. — P. L. S.] 



15. Tanagra bonariensis. {Op. cit. i. p. 39.) 

 (No. 124, (J.) Fortin Page. June 27tli, 1890. 

 Rather frequent during July and August, feeding and 



associating with T. sayaca. 



16. Pyranga AZARiE. {Op. cit . i. p. 40.) 



(No. 130, S') Fortin Page. July 11th, 1890. 



Rare : a few individuals seen about the middle of July. 



17. Tachyphonus melaleucus (Sparrm.); Sclater, Cat. 

 Birds Brit. x\ius. xi. p. 207. 



(No. 169, ? .) Fortin Page. August l(>th, 1890. 



Fairly common about the date mentioned. 



[This is a new addition to the Argentine avifauna, but 

 might well have been expected to occur here. Natterer 

 obtained specimens of it on the Upper Rio Parana (Pelzeln, 

 Orn. Bras. p. 212).— P. L. S.]
