FIGURE 3. A. Plantar view of the right foot of Odontophrynus carvalhoi (CFBH 23425). Note the portion of the FAD with origin from the common tendon of origin of lLBB IV and mLBB V (character 8). B. Plantar view of the left foot of Spea hammondii (CM 73782). Note the distal portion of the FAD with origin from the tendon of the mLBB V (the proximal portion of the mLBB V and its tendon of origin are exaggerated in the shading of the figure for clarity, since they are partly fused to the base of ABP V). Removed elements of Figure 3A, B: TS I–V, LBL III–V, LLG IV, LBB I–V (proximal end of lLBB IV and mLBB V not removed), distal portion of FBS, distal and lateral portion of APLA, distal and ventral portion of distal element of PH; additionally, in Figure 3B, the tendon of origin of the lLBB IV from the FBS was removed. Abbreviations as indicated in Material and Methods. Scale bars = 1 mm.
