a : after Lent and Wygodzinsky (1979) ; b : mean ± two standard errors (SE), with values taken from Harry (1994) ; c : with head length taken from Harry (1994) ; NR: not reported. Note that some measurements are given as ranges and some as the mean ± two SE and are therefore not directly comparable.
