MEMORIAL OF O. H. SAIRX JOHN 35 



Atlantic coast by way of the Rio Sao Francisco and the Rio Paranahyba, 

 while Mr. Ward was to descend Rio Tocantins to the Amazon and Mr. 

 Sceva was to remain for some time in the fossiliferous regions about 

 Lagoa Sancta for the purpose of collecting. The members of the party 

 continued together as far as Juiz de Fora. Thence they crossed the Serra 

 do Mantiqueira to Barbacena and kept on from that place through Lagoa 

 Durada and Prados across the Rio Carandahy to the divide separating 

 the headwaters of the Rio Grande on the south from those of the Rio 

 Paraopeba on the north. They crossed the latter stream just above the 

 water-gap of the Serras of Piedade and Itatiaiassu, traversing the former 

 Serra into the mountain valley in which the village of Morro Velho is 

 situated. They thus found themselves successively in the basins of the 

 Rio Paranahyba, the Rio de la Plata, and the Rio Sao Francisco, all of 

 these streams being fed by rivulets which rise in this vicinity. On leav- 

 ing the mountainous districts they continued their route through alter- 

 nate campos and wooded tracts to Gequitiba, passing through Sabura, 

 Santa Luzia, Lagoa Sancta, and Sette Lagoas. 



At Lagoa Sancta Mr. Sceva remained behind to collect bones of extinct 

 mammalia from the caves in the neighborhood. Mr. Ward separated 

 from his companions at Barbacena. From Lagoa Sancta, Saint John and 

 Allen kept on together to Januaria, where the latter, whose health had 

 been failing from the time that he left Rio de Janeiro, found himself 

 unable to prosecute the journey farther, and he resolved to strike across 

 the country to Bahia, taking in charge the collections they had brought 

 together thus far. 



Leaving Januaria, Saint John followed the Rio Sao Francisco to the 

 Villa do Barra, where he made a short stay, and then resumed his jour- 

 nej by land through the valley of the Rio Grande to the Villa Santa 

 Rita, thence to Mocambo and across the highlands separating the basin 

 of the Rio Sao Francisco from that of the Rio Paranahyba. At Para- 

 nagua he remained several days and made a considerable collection in the 

 vicinity. Thence he followed the valley of the Rio Gurugueia to Manga, 

 one hundred and twenty leagues away. 



At Manga, Saint John embarked on one of the singular river-boats 

 made of the leaf-stalks of the Buriti palm and descended the Rio Para- 

 nahyba to the villa of San Goneallo. Here he stayed for some time to 

 collect, forwarding from this vicinity a considerable number of specimens, 

 chiefly reptiles, birds, and insects. His next station was at Therezina, 

 the capital of the province of Piauhy, where he made one of the most 

 interesting collections of the whole journey from the waters of the Rio 

 Poty. The Poty is a tributary of the Paranahyba, into which it empties 

 below the citv.
