Osvaldo A. Reig

Abstract


In this work the author describes a new 'fossil "ferret" named Galictis (Galictis) sorgentinii, n. sp., known from a lower jaw found in lower Pleistocene beds (Vorohue formation) outcropping in the Chapadmalal region, S.E. of the Province of Buenos Aires (Argentina). He discusses the status of the supr,ageneric classification of the family Mustelidae, considerig that there are good reasons to separate Galictis, Eira, and some extinct close genera, in an own subfamily, as Pocock did, but he names it Galictinae in accordance with the International Rules of zoological nomenclature. He gives a short account of the geology of the region where the new Mustelid was found, on the bases of the new data published by Kraglievich. He gives also the first faunal list of the Vorohue formation:. DiscussIng the relationships of Galictis (G.) sorgentinii n. sp., he concludes that the northa'merican Blancan species Canimartes (?) coocki Gazin may belong to the Genus Galictis, and he points out that the other species described hy Gazin from Idaho, Canimartes (?) idahoensis may be included in the genus Trigonictis Hib. He considers that Trigonictis, and also Lutravus Furlong and Cernictis Hall must he refered to the subfamily Galictinae.
