[7] The Puerto Rico Department of Natural and Environmental Resources considers it a "vulnerable species".

It has distinguishing brownish dorsum, greenish sides, blue eyes, a small white dewlap, a short pale lateral line, and a number of black spots behind the eyes.

[11] Its distribution is rather small, being limited to the arid and semi-arid western half of the southern coast of the island.

[12] It was identified and catalogued in 1902 by Leonhard Stejneger, a curator with the Division of Reptiles and Batrachians of the United States National Museum.

[14] Its discovery and documentation were originally published in Stejneger, 1904: "The herpetology of Porto Rico".
