Another skin arrived at the Paris museum in 1800, collected by Colonel M. Mathieu for the French ornithologist Louis Dufresne. It was sold in 1819 among other items, was sent to Edinburgh, and is now in the National Museum of Scotland as specimen MU No. 624. It was not identified as a Mauritius blue pigeon until the British ornithologist Alfred Newton saw it in 1879. The last specimen recorded was shot in Savanne in 1826 and given to Julien Desjardins, founder of the Mauritius Natural History Museum in Port Louis, where it is still located, though in poor condition. Only these three taxidermic specimens still exist. Subfossil remains of the Mauritius blue pigeon were collected in the Mare aux Songes swamp by Théodore Sauzier in 1889. More were collected by Etienne Thirioux around 1900. They are thought to have been found near Le Pouce mountain and Plaine des Roches.
