The digital formula of this specimen is thus 2,3,3,3,3. Several other specimens show details of the manus. In BPI 2915 (Figs 6, 13A) three digits are present, two of them nearly complete. In two digits, regarded as the second and third, the first and second phalanges are immovably united, and can be distinguished from each other only by a thin line of fusion. Medially a third fused pair of phalanges lies separated from the radiale by a space large enough to accommodate a metacarpal; this probably represents the first digit, with the first and second phalanges fused. The ungual phalanges of the second and third digits are damaged, but that of the third digit is of.
