The anonymous author of the ma.n.u.script ”Relation de l'ile Rodrigue” (see Ann. Sci. Nat. (6) II p. 133 et seq. 1875) about the year 1830 mentions this bird as follows:--”There are not a few Bitterns which are birds which only fly a very little, and run uncommonly well when they are chased. They are of the size of an Egret and something like them.”

Habitat: Rodriguez Island.

ARDEA DUBOISI NOM. NOV.

_Butors ou Grands Gauziers_ Dubois, Les Voyages faits par le Sieur D.B.

(1674) p. 169.

L'Abbe Dubois is the only author who has, as far as I can ascertain, told us that the Island of Reunion also had a large almost flightless Heron as well as Mauritius and Rodriguez; and so feeling sure that it, like most other birds of this island, was distinct I name it after him.

The translation of his original description is as follows:--”Bitterns or Great Egrets, large as capons, but very fat and good. They have grey plumage, each feather spotted with white, the neck and beak like a Heron, and the feet green, made like the feet of Poullets d'Inde (_Porphyrio_, W.R.). This bird lives on fish.”

Habitat: Reunion or Bourbon. {115}
