Carabian? You must mean Caribbean.
Caribbean could be used as a category that would contain Cuban, Haitian, Dominican, Jamaican, Puerto Rican, and the people (do not know the ethnic terms) of Grenada, Barbados, Dominica, Antiqua, Martinique, Guadeloupe, Bahamas, St. Vincent, St. Kitts-Nevis, St. Lucia, et cetera, and possibly even Trinidad & Tobago and Netherlands Antilles.
What about West Indian, or is that considered politically incorrect like American Indian?
I just thought of something different. Carabian could be a word to describe ground beetles (family Carabidae) or certain species of genus Carabus and related genera.
