The Mona ground iguana (''Cyclura cornuta stejnegeri'') is a subspecies of the rhinoceros iguana (''Cyclura cornuta''). It is endemic to Mona Island, Puerto Rico and is the largest native terrestrial lizard in Puerto Rico. == Taxonomy == The Mona ground iguana is a subspecies of rhinoceros iguana belonging to the genus ''Cyclura''. It was named by Thomas Barbour and G.K. Noble as a species in 1916.〔〔 〕 In 1937, Barbour considered it to be a subspecies of ''Cyclura cornuta''. Its generic name (''Cyclura'') is derived from the Ancient Greek ''cyclos'' (κύκλος) meaning "circular" and ''ourá'' (οὐρά) meaning "tail", after the thick-ringed tail characteristic of all ''Cyclura''. The Mona ground iguana's specific name, ''cornuta'', is the feminine form of the Latin adjective ''cornutus'', meaning "horned" and refers to the horned projections on the snouts of males of the species. Its subspecific name, ''stejnegeri'' honors Leonhard Hess Stejneger, who, when writing his ''Herpetology of Porto Rico'' in 1902, suspected this was a new species.〔 Debate continues as to whether this is a valid subspecies and not a different species in its own right. It is known in some scientific circles as ''Cyclura stejnegeri''.〔 〕 Still, others consider it a regional variant of the parent species. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mona ground iguana」の詳細全文を読む スポンサード リンク
