Boa constrictor
In the famous "10th edition of Systema Naturae" of 1758, Carl Linnaeus cited descriptions by Albertus Seba and by Laurens Theodorus Gronovius to erect the distinct species "murina" of his new genus "Boa", which contained eight other species, including "Boa constrictor". The generic name "Boa" came from an ancient Latin word for a type of large snake. The first specimens of "Boa murina" were of immature individuals from in length. In 1830, Johann Georg Wagler erected the separate genus "Eunectes" for Linnaeus's "Boa murina" after more and larger specimens were known and described. Because of the masculine gender of "Eunectes", the feminine Latin specific name "murina" was changed to "murinus".
