A probable mandibular fragment from the same procedence, is also described. These are two new reports for the Early Tertiaiy of Antartica. Previously, in the same ·sediments, was registered a rostral fragment of another Pseudodontornithidae; its size is aproximately twice as large as the one that should have corresponded to the one described above.
