SVENSKA EXPEDITIONEN TILL MAGELLANSLÄNDERNA. BD. II. N:0 7. 155 



This claw was found separately, but on the same spot 

 as the pieces of the skin. It is not exactly provecl that it 

 has belonged to the same animal as the skin, but it seeins 

 more than probable that it really once did so. It cannot be 

 referred to any animal which is known to live in South 

 America at the present time. During such circumstances I 

 think it cannot be wrong to regard this claw as a fragment 

 of »Neomylodon» (conf. below). 



Nos. 8 and 9 are oblong hairballs, which have probably 

 been constituents of the excrements of some carnivorous ani- 

 mal, perhaps a dog belonging to the cave-dweller who once 

 killed the »Neomylodon». It is composed mostly of nne gray- 

 ish yellow wool (of huanaco?) felted together. But it also 

 contains several hairs like those of »Neomylodon-» and some 

 others of a dark reddish brown colonr. In addition to this 

 there can also be seen some pieces of grass and straw and 

 other vegetable matter, although not much. The other hair- 

 ball is much looser, it contains less wool and is chiefly com- 

 posed of the dark red hair mixed with some »Neomylodon-» 

 hairs. The red hairs attain a considerable length up to 15 

 cm. It is not so thick and stiff as that of »Neomylodom but 

 much thicker than the thickest ones of the huanaco. Its 

 structure is also quite different from the same of the »Neo- 

 mylodon» hair, as will be seen later. I cannot say to which 

 animal it has belonged. 



No. 10, the last number of the collection from Cueva 

 Eberhardt, is a piece of hard stone with sharp edges which 

 has apparently been chipped by man. 



It is the remains of »Neomylodon» which above all in- 

 terest us here, and which we want to compare with the cor- 

 responding organs and structures of other animals. We have 

 thus to fix our attention principally on the shape and struc- 

 ture of the dermal ossicles, the structure and distribution of 

 the hair and the shape of the claw of this animal. 



If we then at first consider the ossicles, which have been 

 described above, there are not many mammals which offer 

 any material for comparison. It is only in the representa- 

 tives of the family Dasypodidrc and in the allied, extinct 

 Glyptodontidee, in some members of the likewise, as it seemed 

 certain tili now, extinct Mylodontidce and in some yet living 

 Odontoceti that we meet with dermal ossifications. As has
