182 HAIR OF NEOMYLODON CHAP. 
strange, huge, ugly monster, which had its abode in the Cordillera 
to the south of latitude 37. The Tehuelches and the Gennakens 
have mentioned similar animals to me, of whose existence their 
ancestors had transmitted the remembrance; and in the neigh- 
bourhood of Rio Negro, the aged Cacique Sinchel, in 1875, 
pointed out to me a cave, the supposed lair of one of these 
monsters, called ‘ Ellengassen’; but I must add that none of the 
many Indians with whom I have conversed in Patagonia have 
ever referred to the actual existence of animals to which we can 
attribute the skin in question.” 
A rude painting in a cavern, in red ochre, seems to Dr. 
Moreno (whose words we have just quoted) to be somewhat 
suggestive of a Glyptodon. There are some reasons for beheving 
that this quadruped was kept by man as a domestic creature. 
In the cave are two walls of rough pieces of stone which seem 
to have dropped down owing to the wearing away of the roof; 
they also seem to have been loosely piled together to form two 
walls, within which enclosure an imperfect skull of the animal was 
found. This skull shows clearly that the so-called “ Veomylodon ” 
must be referred to Glossotherium or Grypotheriwm, as it 1s 
sometimes termed. This skull is perforated on the roof in such 
a way as could only have been effected (an the opinion of 
experts) by a weapon in the hand of a man. A hole in the skin 
has been even compared to a bullet-wound. But this it is per- 
haps unnecessary to discuss. The skin of Glossotheriwm is, like 
that of other extinct “ Ground-sloths” (e.g. Mylodon), filled with 
small and irregular ossicles. But in JMJylodon, the sculptured 
appearance of the dermal ossicles appears to indicate that they 
reached the surface of the body and were covered by epidermis 
alone, which is not the case with the animal now under con- 
sideration. _ The microscopic characters of the ossicles, too, show 
differences in the two. Glossotherium being “ precisely inter- 
mediate between MZylodon and the existing Armadillo (Dasypus).” 
Now Gilossotherium and Mylodon are regarded as forms which lie 
between the existing Anteaters and the Sloths of the same part 
of the world. We have already pointed out the facts of structure 
which lead to this conclusion. It might therefore be reasonably 
surmised that the hair of Glossotheriwm would be also inter- 
mediate, or at least like that of one of the two genera Myrme- 
cophaga and Bradypus. But microscopical investigation has
