Obs. This little Parrot does not appear to be nearly related to any other species, and at first sight bears a greater resemblance to some of the small Australian species than to any which are American. Two specimens are in the collection, one brought by Mr. Pease from the vicinity of the National bridge, and the
other collected by Mr. Bruzin, also in Mexico.
