The Lesser Antilles extend from St. Croix m the north to Grenada ,n the south. successful in establishing itself on more than one island bank. Two types of islands may be distin- guished grossly in this archipelago: steep, montane, volcanic islands, which have high rainfall in at least some parts and are ringed either by steep cliffs or beaches of white or black sand; and low, flat, relatively xeric, limestone islands, ringed by white sand beaches only. These flat islands, presum- ably older, lie to the east of the montane islands and are sometimes called the outer chain. The southern limit of this outer chain is Marie Galante and the Grande Terre portion of Guadeloupe. It includes the An- tigua bank and the Anguilla bank. Guade- loupe itself is actually a double island; the western half is very mountainous. The mountainous chain begins in Grenada and continues north through Saba. Lying some- what to the east of the main Lesser Antil- lean double chain is Barbados—also a rela- ti\'ely flat island with little topographic \ ariation. Figure 2 shows the Lesser Antil- lean chain. The Anolis on these islands fall into dis- tinct species groups. Underwood (1959) called the group occupying the southern islands (from Grenada north to Marti- nique) the roquet group; those anoles on the northern islands were placed in the bimaculatus group.
