The Scolopax guarauna of Linnseus was founded upon the Guarauna of Margrave, a name given to a young bird said to have come from Brazil. Although it is impossible to decide with certainty what this bird really was, it is possible that it was the young of the present species, as it is not known that any other species of Falcinellus is found in Brazil. It will be best, however, even if a second species of this genus should be ascertained to inhabit Brazil, to retain the name of guarauna for the present bird, as otherwise a new name altogether would probably have to be given to it, since the only one which has certainly been applied to it, the chalcoptera of Temminck, had already been given previously by Vieillot to an African Ibis. The species has a wide distribution, ranging, according to Ridgway, from Chili and Buenos Ayres to the Columbia river. A white band, enclosing the eye, passes around the entire base of bill. Head, neck, and underparts purplish chestnut. Back with metallic purple and violet reflections. Wings and tail bright green, varying with bronze and purple in certain lights. Shoulders reddish chestnut. Under tail-coverts have also metallic green and violet reflections. Bill apparently dark red. 21. FALCINELLUS RIDGWAYI. Falcinellus ridgwayi, Allen, Bull. Mus. Comp. Zool.

This form, thus far only known from Peru, is closely allied to the previous one, F. guarauna, but seems not to have the white front on the head. Several specimens are in Messrs. Salvin and Godman's collection, sent by Mr. Whitely from Peru. It is probable that the species has been confounded with the F. guarauna; for it seems hardly probable that it should be restricted to Peru, as all its relatives wander over such vast extent of country. It is uot unlikely that its range will be found to be much greater than is at present supposed. Head and neck dark chestnut-red, or purplish chestnut. Back dark green, with metallic purple reflexions. Wings metallic grass-green, with bronze and bright purple reflexions. Primaries bright grass-green. Entire underparts dark purple, the under tail-coverts |
