« Among mammals obtained hy the Field Museum 
before its field work in South America was temporarely dis- 
continued, are a few belonging to species or subspecies not 
as yet described and named. Eight of these, of which the 
status seems reasonably certain, are descrioed below. Two 
new subgenera of rodents, the existence and relationship 
of which were discovered as a result of the recent growth 
of American collections of neotropical mammals, are also 
included. »

« Tamandua tetradactyla instabilis Allen. . . .. If it 
were assumed, as has been done, ( Allen, The Tamandua 
Anteaters, Bull. Am. Mus. Nat. Hist. N. Y. XX, p. 391. Oct 
1904 ), that Guiana is the type locality of tetradactula, it 
might be safer on geographic grounds to refer our specimen 
to that form. But ewamination of the principal literature 
concerned is convincing that Brazil and not Guiana should 
be regarded as the type locality of tetradactila. Linnaeus 
based the name entirely on Marcgrave and Ray, these be- 
ing the only authors cited in the sixth edition of the Sys- 
tema, and only one, Seba, being added in the tenth edition. 
Maregrave referred exclusively to Brazil, and apparently Ray 
also, since he use the words, « Tamandua. In Brasiliensi- 
bus » ( Vide: Erxleben, Syst. Regn. Anim. p. 95. 177. ) ete. »
