What is "macroscincus"

Macroscincus coctei, also called the Cape Verde giant skink, lagarto, or Cocteau's skink, is a species of lizard, a reptile that was at one time known to inhabit the islets of Branco and Raso in the Cape Verde islands of the Atlantic Ocean, rendered deserts by human-caused habitat destruction. No Macroscincus coctei has been observed since early in the 20th century.
