The pectoral girdle in A. valencien- ni is further characterized by an elongated sternum, an expanded suprascapula and a more perpendicularly positioned scapula and clavicula. The pelvic girdle in A. sagrei is generally broader and has an ilium that is directed more dorsallv compared with that of A. valencienni (Fig. 3). The anterior part of the ischium is, however, more elon- gated in A. valencienni. Ligaments (Figs. 2, 3).
