Some years ago I published in this JOURNAL an account of the ferns of central Chile, that is, of the region in which are situated the principal cities, Santiago, the capital, and the port of Valparaiso.' As some of my readers may remember, that is a steppe region of low rainfall, originally covered with a stunted and sparse xerophytic forest and now largely given over to the cultivation of wheat, barley, maize, and legumes, or in the drier parts, especially the hills, to pasture or the raising of ...

The best proof that the southern regions are not Antarctic is the long list of pteridophytes from the Straits-all the more that, as is well known, few groups of plants avoid really cold climates as do ...

La serie de objetos de greda que va reproducida a continuación hallóse en unas sepulturas de San Julián cerca de Ovalle, en la provincia de Coquimbo, y fue adquirida por don Ricardo E. Latcham, director del Museo Nacional de Historia Natural, para su colección particular. Comprende un grupo numeroso y solo he dibujado los ejemplares que me han parecido más característicos para dar una idea general del hallazgo.
