Note AA — CLASSIFICATION.

So far as can be judged from figures, it appears to have but three bones in the wing-finger: what Cuvier regarded as a terminal and fourth joint, the bone n, Pl. XXIII. fig. 7, Oss. Foss., appearing to me to be the fibula of the tibia marked e. s in the same figure would be the terminal phalange, and r the first phalange, as may be proved by measuring them with those of the other hand, so that a phalange is missing from between them. Both the terminal phalanges appear to be hooked at the termination. Goldfuss figures the phalanges so as to make the bone which appears to be fibula in Sömmerring and Cuvier look like a fourth phalange.
