Listed as Extinct on the basis that this species historically occurred on at least four major islands in the Lesser Antilles, three of which have human populations that would undoubtedly have led to the discovery of a living population of this large, conspicuous lizard. While historical literature from Guadeloupe indicates that the species survived into colonial times at least on this island, it is not clear that populations elsewhere were still extant in this period and the reasons for, and date of, its extinction are unknown.

Fossil remains of this West Indies species are known from Anguilla, Barbuda, Antigua, and Guadeloupe (Henderson and Powell 2009). It was probably coastal (Breuil 2002).

The species is almost certainly extinct (Henderson and Powell 2009), as it is a conspicuous species that occurred on three well-populated islands where a surviving population would very likely have been detected (R. Powell pers. comm. 2015); Barbuda is uninhabited, but the species appears never to have been recorded there in historic times. Du Tertre (1667) reported the behaviour of this lizard, indicating that it survived into historical times.
