Malleus and incus morphology among golden moles. A) Amblysomus hottentotus redrawn from Mason reference six: fig. one d; B) Chlorotalpa sclateri redrawn from Mason reference five: fig. three b; C) Carpitalpa arendsi redrawn from Mason reference five: fig. three c; D) Chrysochloris asiatica redrawn from Mason reference six: fig. 1e; E) Eremitalpa granti namibensis redrawn from Mason reference six: fig. one f; F) Chrysospalax villosus redrawn from Mason reference four: fig. seven b. For the purposes of this study, malleus shape is coded using four states: 0-small (head of malleus does not exceed manubrium mallei in longest dimension, as in A); 1-enlarged (head of malleus similar to manubrium mallei in longest dimension, as in B and C); 2-enlarged and globular (head of malleus is pea-shaped and exceeds length of manubrium mallei, as in E and F); 3-club shaped (head of malleus is elongate and over twice the length of the manubrium mallei, as in D). Scale bar = 5 mm.
