TABLE 4. Visceral character states comparing Typhlops coecatus and T. zenkeri with African Letheobia (LET) and American Amerotyphlops (AME) and Typhlops (TYP), 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).
