The translation of Sir Edward Newton's diagnosis is as follows: "Similar to _P. alexandri_, but with a stouter bill, purple red shoulder patches, and the hind neck without a red band.
"_Adult Male._ Crown of head and throat bluish, cheeks ochraceous green, chin and line round base of mandible black, continued in a stripe from the gape to the hind neck; back and wings grass green; rump brighter; a single wide band (or patch) on the shoulders purplish red; remiges and rectrices deep green washed with blue, the latter yellowish, the former dusky below; belly yellowish green; bill vivid scarlet with paler tip; feet dusky. Total length 16 inches, wings 7.75, tail 9."
Female similar to the male but duller, and with the bill all black, and without the black mandibular stripe.
Formerly abundant on most of the islands in the Seychelles, especially Mahé, but now confined to the little islet of Silhouette, where it will in all probability become extinct. According to E. Newton its name was "Cateau vert."

There has been considerable confusion with regard to this parrot. It was first asserted that it occurred on both Bourbon and Mauritius. Then Professor Newton separated the Mauritius bird as _Pal. echo_. Salvadori, however, in Cat. Birds Brit. Mus. XX, p. 442, reunited the Bourbon and Mauritius birds, while quite unaccountably stating only Mauritius as the habitat.
