Excerpt from Experiments in the Breeding of Cerions, Vol. 14 The Florida Keys were considered to be a favorable region into which these Bahama forms might be introduced, for these keys stretch for more than 240 miles from Virginia Key on the north to the Dry Tor tugas in the Gulf of Mexico, and present quite a range in climatic factors and vegetation.
