At Arrecifes, the Glyptodon, sent to the College of Surgeons, was found; and I have seen two teeth of a Mastodon from this quarter. At S. Carlos, I heard of great bones. I have seen, I may add, in the possession of Mr. The furthest point westward in the Pampas, at which I have HEARD of fossil bones, was high up on the banks of R. Quinto.

The route to be taken on the westward journey will be by way of the "island Nublada, discovered by Ruy Lopez de Villalobos" and Roca Partida; then to the islands Los Reyes, the Coral Islands "where you may procure water," and thence to the Philippines; passing perhaps the islands of Matalotes and Arrecifes, in which event they shall try to enter into communication with the natives.

A token and letter must be left at any port they may reach. When the island of Los Reyes is reached, the ship will wait there ten days, after which time they shall continue their course, stopping likewise at Matalotes and Arrecifes, leaving tokens at all places, and trying to explore them and discover their products.

Garcia Descalante Alvarado, who accompanied Villalobos, left an account of the expedition, dated Lisbon, August 7, 1548, and addressed to the viceroy of New Spain; it deals more fully with the later adventures of the expedition. A brief synopsis follows. The next island passed they named Arrecifes or Reefs, the significance of which is apparent.

For some distance northward of Buenos Ayres, the escarpment of the Pampean formation does not approach very near to the Plata, and it is concealed by vegetation: but in sections on the banks of the Rios Luxan, Areco, and Arrecifes, I observed both pale and dark reddish Pampean mud, with small, whitish concretions of tosca; at all these places mammiferous remains have been found.
