author develops the circumstances that gave 

 rise to the fable of the lake Parima ; but the map 

 restores this lake, placing it however far from 

 the sources of the Oroonoko, to the east of the 

 Rio Branco. According to father Caulin, the 

 Oroonoko is called Rio Maraguaca in the me- 

 ridian of the granitic mountain of this name, 

 which is figured on my itinerary map. 6i It is 

 rather a torrent than a river; issuing conjointly 

 with the Rio Omaguaca and the Macoma, in 

 two degrees and a half of latitude, from the little 

 lake Cabiya (Manomaname in Cabre, Caricha 

 in Guaypunabi)." It is this lake, which La 

 Cruz designated as the source of the Maquiri- 

 tari (Padamo), and placed in latitude of five 

 degrees and a half to the north of lake Ipava. 

 The existence of the Bio Macoma of Caulin ap- 

 pears to be founded on a confused idea of the 

 Padamo, the Ocamo, and the Matacona, which, 

 before my travels, were believed to communi- 

 cate together. Perhaps also the lake, from 

 which the Mavaca issues (a little to the west of 

 the Amaguaea), has given rise to these errors 

 on the origin of the Oroonoko, and the neigh- 

 bouring sources of the Idapa*. 



Surville substitutes for the lake Pari me of La 

 Cruz another lake in the latitude of 2° 10', which 

 he regards as the source of the Ucamu (Ocamo).
