Figure 13 in Diversity among New World microhylid frogs (Anura: Microhylidae): morphological and osteological comparisons between Nelsonophryne (Günther 1901) and a new genus from Peru

Figure 13. Pectoral girdles of Nelsonophryne in ventral view. A, Nelsonophryne aequatorialis (KU 178288). B, Nelsonophryne aterrima (KU 30773). Note the absence of a clavicle and procoracoid cartilage in both species. Only the left scapula and suprascapula are shown, and these structures have been deflected into the ventral plane for the purposes of illustration. Black and white stipple represents bone, whereas grey tone is cartilage; stippling in grey represents mineralization of the cartilage.
