On the banks of the Santa Cruz, in 50 degrees south, I saw a frog; and it is not improbable that these animals, as well as lizards, may be found as far south as the Strait of Magellan, where the country retains the character of Patagonia; but within the damp and cold limit of Tierra del Fuego not one occurs.

That the climate would not have suited some of the orders, such as lizards, might have been foreseen; but with respect to frogs, this was not so obvious.
Beetles occur in very small numbers: it was long before I could believe that a country as large as Scotland, covered with vegetable productions and with a variety of stations, could be so unproductive.

The few which I found were alpine species (Harpalidae and Heteromidae) living under stones.

The vegetable-feeding Chrysomelidae, so eminently characteristic of the Tropics, are here almost entirely absent (11/5.

I believe I must except one alpine Haltica, and a single specimen of a Melasoma.
