guanca and of la Viuda. The table-land of 

 this knot of mountains appears in the Pampas 

 de Bombon *, to be more than 1800 toises 

 above the level of the Ocean. From this point, 

 on the north of the parallel of Huanuco, (lat. 

 11°) the Andes are divided into three chains, 

 of which the first, and most eastern, rises be- 

 tween Pozuzu and Muna, between the Rio Hu- 

 allaga, and the Rio Pachitea, a tributary of the 

 Ucayali ; the second, or central, between the 

 Huallaga, and the Upper Maragnon ; the third, 

 or western, between the Upper Maragnon and 

 the coast ofTruxillo and Pay ta~f~. The eastern 

 chain is a small lateral branch which lowers 

 into a range of hills ; directed first towards the 

 N.N.E., bordering the Pampas del Sacramento^ 

 afterwards towards the W.N.W., where it is 

 broken by the Rio Huallaga, in the Pongo, 

 above the confluence of Chipurana, the eastern 

 chain loses itself in 61° of latitude, on the north- 

 west of Lamas. A transversal ridge seems to 

 join it with the central chain, south of Para- 

 mo^, de Piscoguanuna (or Piscuaguna), west 

 of Chachapoyas. The intermediary or central 

 chain stretches from the knot of Pasco and 

 Huanuco, towards the N.N.W. between Xican
