The study of Oxfordian Perisphinctidae (Ammonoidea) from the Andean Province (Chili) shows a marked Iow share of typically european representatives (Perisphinctinae), the proportion being somewhat higher in the case of true tethyan elements (Passendorferiinae), and specially high for cuban elements (Vinalesphinctes). lt seems, therefore, adequate individualising this last genus and related forms under a new subfamilial taxa: Vinalesphinctinae, nov. Its origin as a true Eastern Pacific Realm group, or else, as a «peripheral stem» of Tethyan stock, is stil under discussionEl estudio sobre el Perisphinctidae Oxfordiense (Ammonoidea) de la provincia de los Andes (Chile) nos muestra una porción marcada baja de representantes típicamente europeos...
