The Mammalian fauna of the Santa-Cruz beds 
of Patagonia. 
By W.-B. SCOTT (Princeton). 
As is probably known to many members of the section, Princeton Uni- 
versity maintained exploring expeditions in Patagonia during the years 
1896 to 1899, under the leadership of the lamented Mr. Harcner. Owing 
to the indomitable energy and skill of Mr. Harcner and his associates, 
these expeditions were very successful in making extensive and valuable 
collections in nearly all departments of natural science, but the most 
important is undoubtedly the remarkable series of fossil mammals ga- 
thered from the Santa Cruz beds. 
The liberality of J. Pierpont Moreax, Esq. of New-York, has made it 
possible to publish in an adequate manner the reports of the expeditions, 
and I take much pleasure in presenting to the members of the Con- 
gress, for their inspection, such parts of these reports as have already 
appeared. 
The admirable work of the brothers AmeGnino long since attracted 
the interest ard attention of palaeontologists to the vertebrate fossils of 
Patagonia, but much work remains to be done before we can satisfacto- 
rily interpret this wonderful assemblage of animal types, 
In what follows I shall assume that the Santa-Cruz beds are of Mio-
