Table 5- Regression equations, correlation coefficients (r), and probability values (P<) for maxillary length and number of mandibular teeth (Y)
 versus standard length (X) for those populations (males and females combined) of Chasmodes in Table 3 showing no significant sexual
 dimorphism in these characters. (Species and populations are designated using the abbreviation in Table 3.)
