This group of animals is represented by several fragments of the 

 coosified plates of the carapace or exoskeleton of one or more species. 

 They have been assigned the number 11030 in the Carnegie Museum 

 Catalog of Fossil Vertebrates. If the National Museum of La Plata 

 ■were easily accessible, it is quite possible that we might be able to 

 approximately locate these bits of boiies in their proper place in the 

 system of classification. 



Incert^ Sedis. 



Under No. 11035, Carnegie Museum Catalog of Fossil Vertebrates, 

 we have placed several broken and much abraded centra of vertebra?, 

 which are indeterminable. They may represent parts of some of the 

 animals hereinbefore mentioned, or they may not. Quien sabe? 



Among the undetermined and apparently at the present moment 

 indeterminable material in the collection is a piece of what seems to be 

 the shaft of the tibia of a large ground-sloth. It cannot be referred 

 to Megatherium. In size, but not in outline, it is large enough to 

 have belonged to a very large Megatherium. It is inexpedient at 

 present to attempt to place it more definitely.
