The first collections of Interatheriinae (Interatheriidae, Notoungulata) were created by the brothers Florentino and Carlos Ameghino, based on fossil specimens collected from diverse outcrops Argentina housed at different national institutions. In order to perform a systematic study subfamily, it is essential revise as much possible, but all those that used establish respective species, is, type material. Ameghino never referred collection number species he erected in any his publications; this fact added occasional absence illustrations adequate descriptions, which make their identification complex task. Thus, when studying within Protypotherium Patriarchus, we recognised lack correspondence between some appeared labelled types original descriptions these species. contribution, identify eleven eight Patriarchus founded Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" (Buenos Aires, Argentina) Zoological Museum University Copenhagen (Denmark). Three case studies are presented: a) correctly identified; b) erroneously catalogued material; c) not established Ameghino's catalogue, herein such. Lectotype paralectotype P. antiquum designated.
