Description: This report is the first of two planned works detailing the descriptive and comparative anatomy of the xenarthran ear region (basicranium and its immediate surrounds, including middle ear, but not the inner ear). The study was begun by Patterson and Segall in 1945 and continued actively well into 1955, and only fitfully by Patterson thereafter. This part, "Cingulates," covers a representation of the Cingulata (= Loricata), including dasypodoids (Utaetus group, Priodontes group, Dasypus group, Euphractus group, Peltephilus group, and Chlamytherium group) and glyptodontoids. In all, details are given for 10 living and 15 extinct species. The anatomical details largely support most accepted views of cingulate systematic relationships; there are few surprises. It is confirmed that the pampatheres have a decidedly glyptodont-like basicranium, and it is noted that Bordas had stressed this same point in 1939b paper.
