The Jamaican Curly-tailed Lizard was described in 1966 based on fossil or subfossil left dentary that had been recovered from Dairy Cave 2,5 kilometers away from Dry Harbour in the parish of St. Ann, Jamaica, as well as several other remains from other caves on the island.
In life, the species might have reached a size of about 26 to 30 cm or even larger (including the tail). [1][2]

The species survived into historical times, some of the remains that have been found were unmineralized and had been collected from surface deposits. [2]
