Leguat's, d'Heguerty's, and the Abbé Pingré's descriptions were all we had of this great ground pigeon down to 1866, except a few bones. When Mr. Strickland proved its distinctness from the Dodo of Mauritius in 1844, and up to 1852, these bones numbered 18. In 1864 Mr. E. Newton and Captain Barclay got 3 more bones, in 1865 Mr. Jenner, the resident magistrate, collected 8 bones, and in 1866 nearly 2,000 bones were collected, but during the Transit of Venus expedition in 1874, a thorough search was made, and a number of complete skeletons was collected. Habitat: Island of Rodriguez. Represented in Museums by a number of complete skeletons and a large number of bones.

Linnaeus' brief diagnosis is: "Tetrao pedibus hirsutis alis succenturiatis cervicalibus." After the habitat he adds: "Color Tetricis feminae; vertex subcristatus; a tergo colli duae parvae alae: singulae pennis quinque." This diagnosis is taken from Catesby, who gives a fairly good description and a recognizable coloured plate. He specially mentions that the neck-tufts are composed of five feathers, and in his figure they are shown to be much pointed. Catesby expressly states that he does not know exactly from which part of America his specimen came--yet Linnaeus says "Habitat in Virginia."
