HnDLiCicA] SKELETAL REMAINS OF EARLY MAN 263 



"In Santiago del Estero (Rio Hondo) fossil skulls and bones of 

 two very distinct races of man were discovered; one strong and of 

 large stature, apparently not widely different from the normal form, 

 and the other very small and seeming to present some relations with 

 the Negritos (?).[^] At Necochea new examples of Homo pampseus 

 were gathered. To the north of the [Arroyo] Moro, fronting on the 

 Laguna Malacara, some 60 km. north of Necochea, there were recently 

 discovered in the ancient Pampean two skeletons with their skulls, 

 belonging not to a race merely, but to a real (verdadera) extinct 

 species, of reduced stature, with only four lower molars in place 

 of five (the posterior being absent), and possessing a lower jaw with- 

 out a cliin, like that of Spy and Krapina. And in the Superior Pam- 

 pean of Arroyo Siasgo there was discovered a skeleton of human 

 type, but exceedingly primitive and as simian, or perhaps even 

 more simian, than the Homo pampseus. 



"The last-mentioned species is named by me Homo caputinclinatusJ' 



The specimen representing the species "is a fossil human skeleton, 

 found in January of the present year by the traveUng naturalist of 

 the Museo Nacional, Sr. Carlos Ameghino, in a barranca of the 

 Arroyo Siasgo, some 300 meters from the house of the estancia 'La 

 Georgina' belonging to Sr. J. M. Mendez, in the Department of 

 Ranchos, near the station Villanueva of the Southern R. R. 



"With the object of satisfjdng myself as to the position which 

 the skeleton occupied, I visited the locality about the middle of 

 last March. 



"The Arroyo Siasgo is a small affluent of the Rio Salado. . . . 



"Before coming to the Salado, which it reaches through a very 

 narrow channel, the valley of Siasgo broadens in an extraordinary 

 manner, forming a deep depression 4 km. long and 2 km. broad. 

 This hollow, now dry, was in a recent epoch a lake which dried up, 

 its waters draining into the Salado. 



"This depression is limited on the east by a barranca, about 8 

 meters high, against which broke the waters of the lake. This 

 barranca is a part of the remnant of an ancient and high table-land, 

 which, in other times, separated the Siasgo from the Salado; the 

 most elevated part of it has already disappeared. 



"The terrane of this table-land (meseta) is formed by a layer of 

 vegetal earth, some 50 cm. in thickness, which passes gradually 

 into a light eolic loess of reddish-gray color, that somewhat lower 

 becomes more compact. 



''This loess deposit of the barranca of the Siasgo was described 

 in a masterly manner in 1863 by Burmeister, who encountered in 

 it many fossils, now preserved in the Museo Nacional of Buenos
