Note 122 — Chapter XIII
Reading edition
Its actual source is the Rio del Valle, which runs northward through the Valle Vicioso. Its longest tributary, the Curaray, rises only a few miles to the south in the Cordillera de los Mulatos. The two rivers run side by side 4° of longitude before meeting. Coca, the northern branch, originates in the flanks of Cayambi. The Napo and its branches are represented incorrectly in every map we have examined. The Aguarico is confounded with the Santa Maria and made too long, and the Curaray is represented too far above the mouth of the Napo. There are no settlements between Coca and Camindo.
