Mr. P. L. Sclater on the Genus Spermophila. 5 



Hah. Southern Brazil, Bahia (^Mc/terer), Rio {Mus. P.L.S.), 

 S. Paulo, Araguay and Matto-dentro {Natt.). 



This appears to be a common species in collections from 

 Bahia and Rio. I have a pair from the latter locality ; and in 

 the Smithsonian collection are two males from Bahia, whence I 

 have also seen many other skins. Natterer collected numerous 

 examples of this Spermophila in various localities in the provinces 

 of S. Paulo, Goyaz, and Matto-dentro. It was found feeding 

 among the grasses in the campos and at the borders of the 

 streams. 



There are two mounted specimens in the Paris Museum 

 marked as types of " Loxia fraterculus, Cuvier.^^ One of them 

 is of this species ; the other belongs to S. pileata.

Lactescenti-alba, cinnamomeo vix tincta, interscapulio obscure 

 variegato : pileo, alis et cauda nigris, his fusco marginatis : 

 speculo alari albo : rostro nigro : long, tota 3*8, alse 2'1, 

 caudse 1*2. Fern, olivaceo-fusca, alis caudaque obscuriori- 

 bus : subtus ochracea, ventre pallidiore. 



Hab. Brasil. merid., prov. S. Paulo (Natt.) ; Monte Video 

 {Mus. Berol.) 



This species only difi"ers from the preceding in the cinnan}on 

 colour of the body being replaced by a pale milky white; but I 

 am not aware of the existence of intermediate forms. Natterer 

 obtained many specimens of it in various parts of the province 

 of S. Paulo. In 1864 I described it from one of his skins, whicn 

 is still the only specimen of this species in my collection. Ac- 

 cording to Burmeister it is the Sp. mitrata of Lichtenstein in 

 Mus. Berol. But Burmeister is quite in error in referring it to 

 S. alaudina, Lafr. et D'Orb., that name, as I have ascertained 

 by reference to the types, having been bestowed upon immature 

 examples of S. telasco.
