But examination of the principal literature concerned is convincing 
that Brazil and not Guiana should be regarded as the type locality 
of tetradactyla. Linnzus 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.’’* Sub- 
sequent authors, so far as consulted, almost invariably give Brazil 
or Brazil and Paraguay as the habitat of tetradactyla. In one case,’ 
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 Linneus, bivittata Desmarest, opisthomelas Gray, and 
straminea Cope, all from Brazil, it is difficult to see how room can 1 be 
found for still another. '
