circumstance, of which my own experience 

 furnished me with frequent proofs, — that the 

 cataracts in this part of South America are 

 often caused only by ridges of rocks which 

 do not form real mountains. Rodriguez names 

 but two between Barcelonetta and the mission 

 of San Jose ; while the missionaries place more 

 to the east, in 6° latitude, between the Rio 

 Carony and the Cuyuni # the Serranias of Usu- 

 pama and Rinocote. The latter crosses the 

 Mazaruni, and forms 39 cataracts in the Esse- 

 quibo-f-, from the military post of Arinda (lat. 

 5° 30') to the mouth of Rupunuri. 



With respect to the continuation of the sys- 

 tem of the mountains of Parime, south-east of 

 the meridian of the Essequibo, the materials 

 are entirely wanting for tracing it with 



of the Paragua and the Paraguamusi, from north to south, the 

 confluence of the Carony and the Rio Paragua j the mouth of 

 the Rio Hore j the Cerro, Paragua, near the western bank of 

 Paragua ; Raudals of Orayma, Guayquirimatand Carapo ; 

 the Cerro del Gallo ; the village of San Jose j the mouth of 

 Cano de Espuma j the Raudals of Guayguari and Para j the 

 great Raudal of Mayza j the Boca of Cano Icapra ; the Boca 

 of Paraguamusi, and the Raudals of Anocapra. (Razon de

 Reverendos Padres Capuchinos de Carony, fol. 7-\b manu-
