But examination of the principal literature concerned is convincing 

 that Brazil and not Guiana should be regarded as the type locality 

 of tetradactyla. Linnaeus based the name entirely on Marcgrave and 

 Ray, these being the only authors cited in the sixth edition of the 

 Systema, and only one, Seba, being added in the tenth edition. 

 Marcgrave referred exclusively to Brazil, and apparently Ray also, 

 since he uses the words, "Tamandua I Brasiliensibus. " 1 Sub- 

 sequent authors, so far as consulted, almost invariably give Brazil 

 or Brazil and Paraguay as the habitat of tetradactyla. In one case, 2 

 Brazil is definitely stated to be the type locality. The fact that the 

 name tamandua is of Brazilian origin also is worthy of consideration. 

 If, therefore, it is necessary to consider tetradactyla as Brazilian, the 

 status of Tamandua t. chapadensis becomes involved, for with tet- 

 radactyla Linnaeus, bivittata Desmarest, opisthomelas Gray, and 

 straminea Cope, all from Brazil, it is difficult to see how room can be 

 found for still another.
