210 To the River Plate and Back 



told me he had some of them with him on board. They 

 were produced by him, and very kindly presented by 

 him to me. Since then he has forwarded to the Car- 

 negie Museum a large assemblage of the remains ob- 

 tained at the same locality. Among the things put 

 into my hands on shipboard was a fragment of the tusk 

 of a mastodon, the tooth of a fossil horse, and the tooth 

 of a Toxodon. Availing myself of the courteous assist- 

 ance of Dr. Roth a comparison of the latter specimen 

 was made with the abundant material in the Museum 

 at La Plata, with the result that we came to the con- 

 clusion that the tooth belongs to Toxodon burmeisteri, 

 the giant of the family. The late Professor E. D. Cope 

 founded a species of Toxodon upon a single tooth com- 

 ing from the Province of Bahia, the only case in which 

 such animals have hitherto been reported from that part 

 of the continent, but I have no hesitation in saying that 

 the specimen presented to me by Mr. G. A. Waring repre- 

 sents the species I have mentioned. The range of this 

 huge animal is thus extended far to the north. Re- 

 mains of Toxodon have been reported from Central 

 America, but thus far no record of their occurrence upon 

 the soil of the United States has been made, and save 

 for the case cited by Cope there has been no prior 

 account of their occurrence in northern Brazil. 



From the authorities of the Museum in La Plata I 

 received replicas of many of the fine specimens con- 

 tained in their Museum as a gift for the Carnegie 

 Institute. I also received a piece of the skin, some hair, 

 and some of the ordure of Grypotherium obtained at 

 Last Hope Inlet. "Thereby hangs a tale,' which I 

 will proceed to unfold in the next chapter. For these 

 acts of great kindness on the part of the Faculty of the 

 Museum in La Plata, I desire here to renew my thanks.
