Etymology
editThe specific names, brazili and spixii, are in honor of Brazilian herpetologist Vital Brazil and German biologist Johann Baptist von Spix, respectively.[2]
Conservation status
editThe St. Vincent Blacksnake, Chironius vincenti is listed as critically endangered by the IUCN Red List due to its extremely limited range on the Island of St. Vincent.
