Nabayuganes (24).
These people, who have a language of their own, live in two long valleys extending from the Cordillera Central towards the east. According to D’Almonte’s map, these parallel valleys lead down to the town of Malaneg, and in each of them there is a river. That in the northern valley is called the River Nabbuangan, and that in the southern valley the River Nabbuanguan. They join before reaching Malaneg, forming the River Nagalat, a tributary of the Rio Chico de Cagayan. Nothing is known of their religion or nature. On the north-east of the Nabayuganes live the Aripas.
