In number of supra- orbitals in contact with the interparietal, 0/0 is the mode in all samples except that from Great Ragged, which has 1 /I modally (although 0/0 has a freciuency of two lizards and 1/1 a frecpiency of three lizards). All samples modally have 2^2 scales in lateral contact with the postfrontals. The highest incidence of complete median sep- aration of the supraorbital semicircles oc- curs on Long Island (four of 53 lizards), whereas New Providence has three of 46, the Exumas one of 16, and none occurs on Great Ragged. Scales across the snout range from 4 to 6 (New Proxidence), 8 (Exumas), or 7 (Long), and are either 5 or 6 on Great Ragged; modes 4 (New Providence), 5 (Great Ragged) and 6 (Exuma (]ays. Long). Loreal rows \ar\' from 3 to 5 on New Providence (mode 4), and 4 to 6 on the Exumas (mode 4) and Long (mode 5); loreal rows on Great Ragged are 4 or 5 (mode 4). Fourth toe lamellae vary from 15 to 20 (New Provi- dence, the Exumas), 14 to 19 (Long), and 15 to 19 (Cireat Ragged), with modes of 18 in the former two samjiles and in the Great Ragged lizards, and 17 on Long Island. Median azygous head scales vary between 3 and 13 (mode 5, mean ) on. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - co
