N.ParthaniiGiannettusi, Koi. No. 31. JULY 1900. T. — On some Fi.ih-retmiin.t from the Parana Formation, Argentine Republic. Hj A. Smith WoODWAKD, LL.I)., F.L.S. [Plate I.] There is an interesting marine deposit exj)03ed in the b.mlcs of the River Parana near the city of Parana, in the province of Entrerios, Argentine Republic. It has been known since tlie explorations of d'Orbigny arid Darwin, and is of special importance not only as containing the remains of land-mammals itself, but also as being intimately associated with other deposits which yield abundant evidence of extinct mammalian faunas. Since marine fossils are of much more value in determining the age of a formation than the remains of land animals, this small Parana deposit may therefore be expected to afford a clue to the geological age of some of the Soutii-Anierican terrestrial faunas, concerning which various opinions have been expressed. Its interest in this connexion has already been recognized by several observers, including Ann. <X-Mu(j. A". Hist. S.-r. 7. Vol. vi. I
