TABLE 8. Visceral character states comparing Anilios ("Sundatyphlops”) polygrammicus with Anilios (ANI), based on measurement of the specimens in Appendix II (part). Characters are as follows: data in sections (A)-(D) represent sample means as % SVL; organ lengths (PT = posterior tip) are included in section (A); organ midpoints (MP) are listed in section (B); organ gaps (GAP) and intervals (INT) are compiled in section (C); organ midpoint intervals (MP-MP INT) are included in section (D); meristic values are listed in section (E); ratios of two characters listed in (F).
