This species is known from subfossil remains that were recovered from archaeological sites on the small island of La Desirade off the northeast coast of Guadeloupe in the Lesser Antilles.
The remains were dated to about 600 to 1400 AD..

This undescribed form, which may or may not be related to or even conspecific with the Barbuda Curly-tailed Lizard (Leiocephalus cuneus Etheridge) is known from subfossil remains of Latest Holocene age found in 1984 in an unnamed cave at Pointe du Capucin at the northern shore of the island of Basse Terre in the Guadeloupe archipelago.
The Guadeloupe Curly-tailed Lizard survived into historical times, the remains have not yet been dated but were found associated with the bones of rats, which were introduced to the Caribbean only in the 15th century.

Guadeloupe House Wren (Troglodytes aedon ssp. guadeloupensis)
This form, described in 1886, occurred on the islands of Basse Terre and Grande Terre, Guadeloupe.
The Guadeloupe House Wren reached a length of about 11,5 cm, it was quite like the Grenada House Wren (Troglodytes aedon ssp. grenadensis (Lawrence)) (see photo) or the Martinique House Wren (Troglodytes aedon ssp. martinicensis (Sclater)), differing by its shorter wings.
The form was last recorded during field observations from 25 May through 1 June of the year 1973.:
“At 10:30 while standing at the beginning of the trail at the end of the raod a wren sang a few meters down slope then flew to a perch in bright sunlight. We observed it with 7 x 50 binoculars for 1 min at a distance of 10 m, recognizing it as a Guadaloupe House Wren before it flew into dense brush.” 
During these field observations at least five birds where seen, including at least four singing males.

This somewhat enigmatic form is known on the basis of two skeletal remains, both found on the small island of Marie-Galante, an island in the Guadeloupe archipelago; the first one is a subfossil ulna that had been recovered from the Folle Anse archaeological site and the other one is a very much older phalanx recovered from cave deposits that are of Late Pleistocene age.
The Marie-Galante Macaw most likely wasn’t a distinct species but was identical with the Guadeloupe Macaw (Ara guadeloupensis Clark), for which, however, no skeletal specimen exists and which thus still is considered a hypothetical form.

The Martinique Giant Ameiva was described in 1839; it is known exclusively from museum specimens, whose origins appear to be unknown, they may have come from the island of Martinique or from the so-called Les Iles de la petite Terre, offshore Guadeloupe.
The species disappeared most likely due to predation by introduced mammalian predators.
The Guadeloupe Macaw aka. Lesser Antillean Macaw is the best presented Caribbean macaw species, regarding contemporaneous accounts.
The first of these accounts dates from 1553, comes from the Spanish historian Gonzalo Fernández de Oviedo y Valdés and is itself referring to another account from 1496, made by Fernando Colón (Ferdinand Columbus), a Spanish bibliographer and the second son of Cristoforo Colombo (Christopher Columbus), who again mentions chicken-sized parrots, which the Island Caribs called Guacamayas, in Guadeloupe. 
There are very detailed accounts made by Jean Baptiste Du Tetre in 1667, who not only describes the bird in detail but also gives some information about its life and the way it was hunted by the natives and so on. 
A subfossil terminal phalanx, found in late Pleistocene cave deposits on the island of Marie-Galante, a small island offshore the east coast of Basse Terre and Grande Terre, Guadeloupe, has been assigned to a Ara sp., another skeletal remain; a single subfossil ulna recovered from an archaeological site on the same small island is also assignable to a Ara sp.. These two remains are the only evidence for the former presense of a macaw species on the Guadeloupe archipelago. 
The St. Croix Macaw (Ara autochthones Wetmore), which is known from several subfossil remains, as well as the undescribed Montserrat Macaw (Ara sp.) known from subfossil remains from the island of Montserrat, might be identical with this species.
