The mountain racket-tailed parrakeet was discovered by Whitehead in the mountains of Abra and Lepanto Provinces. At San Jose a live bird was purchased. The natives said it "had been snared in their maize-fields and that it was common enough when the cereal was ripe." We collected a number of specimens in Benguet Province where it was not uncommon though somewhat difficult to secure; the species is well known to the Igorot by the name "u-lis." It is improbable that this beautiful parrot occurs below the pine belt but with our meager knowledge of the vertical distribution of birds in the Philippines it is better to follow this statement with a large interrogation mark. This species is very noisy and does not differ in habits from lowland members of the genus. 237. PRIONITURUS DISCURUS (Vieillot). PHILIPPINE RACKET-TAILED PARRAKEET.
