Minas Geraes " prope paf^os Tejuco et Contendas." However, the 

 types of T. majoi' and T. niedius are said by Hellmayr to have the 

 rufescent cast of the dorsal surface found in N. vi. maculosa, while 

 N. m. minor is a small form so that none of these names can apply to 

 the bird I have described as savam/naru'tri. The Nothura media of 

 Salvadori^^ is a synonym of TV. m. minor (Spix). While Nothura 

 assimilis G, R. Gray ^^ described from " South America " is also 

 identical with .V. m. minor.-^ 



Near La Paloma, port of the town of Rocha, the spotted tinamou 

 was seen on January 23, 1921, while from January 25 to February 

 2 it was common near San Vicente, Avhere the birds were especially 

 abundant in g^rassy fields near the Lnguna Castillos. The female 

 described as the type of the present form, taken here on January 

 27, contained a Avell-formed egg almost ready to be laid. The 

 birds were heard whistling in all directions, and half-grown young 

 were seen on January 30. From February 3 to 9 they were noted 

 in numbers near Lazcano. 



NOTHURA MACULOSA BOLIVIANA Salvadori 



Nothura hoUviana Salvadobi Cat. Birds Brit. Mus., vol. 27, 1S95, p. 561. 

 (Bolivia.) 



Specimens of the spotted tinamou taken at Las Palmas, Chaco, 

 Kilometer 182 (Riacho Pilaga), Formosa, and Kilometer 80, Puerto 

 Pinasco, Paraguay, are representative of the Bolivian form, though 

 with adequate material there is no question but that they will be 

 found to constitute one or more distant races allied to that bird. 

 In general they are characterized by a strong grayish cast above and 

 below, with the markings of the underparts restricted, and on the 

 breast formed into lines. All are sharply cut off from the brighter 

 colored Nothura m. maculosa and N. m. nigroguttata that range 

 east and south of the Chaco. {Nigroguttata is said to occur at 

 Mocovi, Santa Fe, in the southern end of the Chaco region.) Three 

 distinct types of coloration are represented by the three localities 

 from which specimens called here boliviana are available. A female 

 taken at Las Palmas, Chaco, on July 16, 1920, differs from others 

 here described under the name N. m. holiviana, in being more 

 deeply buff in coloration, especially on the wings and sides of the 

 neck, and in having bolder, heavier black markings on the hind 

 neck. Two males from the Riacho Pilaga, 10 miles northwest of 

 Kilometer 182, Formosa, taken August 15 and 18, are much grayer 

 than this Las Palmas bird, and have the hind neck grizzled with
