See text for explanation. Abbreviations: ant-pt, anteriorly directed pteroid; bra, brachiopatagium; cyc, leading edge of larger propatagium; cyc-ant-pt, Cycnorhamphus-length anteriorly directed pteroid; ext, leading edge of extensive propatagium; fem, femur; hum, humerus; mc, metacarpus; med-pt, medially directed pteroid; pc, preaxial carpal; pro, propatagium; r+u, radius and ulna; tib, tibia; trad, leading edge of traditional propatagium; uro, uropatagium; and wp1-4, wing phalanges 1-4."
