Females have from 37 to 47 (mean, 42.0 +- 0.20; N = 79) subcaudals; males
have from 43 to 55 (mean, 48.4 +- 0.23; N = 109; Fig. 3). Of the 187
specimens examined, 13 (7.0%) have the last pair of subcaudals fused.
One specimen has left subcaudal 28 fused with both adjacent subcaudals
(also fused) on the right. While reading proof we found two omissions in
Fig. 3; there should be illustrated two males with 43 subcaudals and
three males with 44 subcaudals.
