III. Description of Additional Discoveries. 

 By A. Smith Woodward* 



Last February, when presenting to the Zoological Society an account 

 of the skin of a Ground-Sloth discovered in a cavern in Southern 

 Patagonia, Dr. Moreno mentioned that further excavations were being 

 made in the hope of finding other remains of the same animal. The 

 task referred to was undertaken by Dr. Rudolph Hauthal. geologist of the 

 La Plata Museum, who met with complete success. f He not only found 

 another piece of skin, but also various broken bones of more than one 

 individual of a large species of Ground-Sloth in a remarkably fresh state 

 of preservation. ^Moreover, he discovered teeth of an extinct horse and 

 portions of limb-bones of a large feline carnivore, in association with 

 these remains ; he likewise met with traces of fire, which clearly occurred 

 in the same deposits as the so-called Neontylodon. All these remains 

 were found beneath the dry earth on the floor of an enormous chamber 

 which seemed to have been artificially enclosed by rude walls. In one 

 spot they were scattered through a thick deposit of excrement of some 

 gigantic herbivore, evidently the Ground-Sloth itself; in another spot 

 they were associated with an extensive accumulation of cut ha)'. Dr. 

 Hauthal and his colleagues, indeed, concluded that the cavern was an 

 old corral in w^iich the Ground-Sloths had been kept and fed by man. 



As the result of these explorations. Dr. Moreno has now the gratifica- 

 tion of exhibiting to the Society complete proof that the piece of skin 

 described on the former occasion belongs to a genuine Pampean Ground- 

 Sloth, not Mylodon itself, but a very closely related genus Grypotlwriinn, 

 of which skulls are already known from Pampean deposits in the Province 

 of Buenos Aires.i The collection which we now have the privilege of 

 examining distinctly supports his contention that the large quadruped m 

 question belongs to an extinct fauna, though contemporary with man.
