Abstract

THE marsupial or pouched mammals of Australia are well known to include groups which are parallel in form and habits to many groups of the higher mammals living in the rest of the world. The pouched mammals of South America, both past and present, are less varied and represent only insect-eaters and flesh-eaters. Among the latter, however, Dr. Elmer S. Riggs has just described perhaps the most remarkable mimic of a higher mammal hitherto discovered. In a Pliocene deposit in Catamarca, northern Argentina, he has found the remains of a pouched mammal which nearly resembles the familiar Machserodonts or ‘sabre-toothed tigers’, but is clearly inferior in the less efficient adaptations of its skeleton to its mode of life.
