FIGURE 3 in At the lower size limit in snakes: two new species of threadsnakes (Squamata: Leptotyphlopidae: Leptotyphlops) from the Lesser Antilles

FIGURE 3. Variation in scalation of threadsnakes (Leptotyphlops) from three islands in the Lesser Antilles. (A) Head scalation (top and side of head) in representatives from each island (USNM 564809, 564810, 564819). Scale bar = 1 mm. Numbered head scales are rostral, RO (1); prefrontal, PF (2); frontal, FR (3); interparietal, IP (4); interoccipital, IO (5), postnasal, PN (6); preocular, PO (7); parietal-I, PA1 (8); parietal-II, PA2 (9); and ocular, OC (10). (B) Plot of parietal-1 scale width versus length. (C) Plot of parietal-2 scale width versus length.
