FIGURE 2 in A review of the taxonomy and osteology of the Rhombophryne serratopalpebrosa species group (Anura: Microhylidae) from Madagascar, with comments on the value of volume rendering of micro-CT data to taxonomists

FIGURE 2. Definition of skeletal measurements taken for this study: (a) snout length, from the anterior frontoparietal to the anterior premaxilla; (b) brain case width, at mid-orbit; (c) skull length, from occipital condyle of exoccipital to the anterior premaxilla; (d) maximum skull width, typically at the middle of the quadratojugal (not landmark-based); (e) parasphenoid length; (f) parasphenoid width, at mid-orbit; (g) length of parasphenoid cultriform process; (h) distance from parasphenoid alae to waist of cultriform process (the waist being a distinct discontinuity in the angle of expansion of the cultriform process); (i) coracoid width at glenoid socket; (j) coracoid width at thinnest point; (k) coracoid width at sternal end; (l) length of anterior edge of coracoid; (m) length of posterior edge of coracoid; (n) length of anterior face of scapula, (o) length of urostyle; (p) distal width of sacral diapophysis; (q) base width of sacral diapophysis; (r) length of acetabulum; (s) distance between anterior tips of iliac shafts; (t) length of femur from condyle to condyle; (u) length of tibiofibula from condyle to condyle. Not to scale.
