The smaller snakes either go unnoticed, or seem to have adapted themselves to civilization. In this regard I am thinking especially of Micrurus, which is widely distributed and fairly common over its range. But the boas, Sun- badoras, micasalas, rattlesnakes, and other lar- ger forms are bound to suffer, as they have about Monte Cristo. Therefore it is well that these mountain tops are being collected now, as they will undoubtedly be radically changed from their original state within a few years. This area is not well suited to for herpetological collecting, as it is not hot enough to support a va- r[illegible] reftile population, and not moist enough, as are true cloud forest areas, to support a varied amphibian population. It is more or less between the reptile and the amphibion zones, and consequently the representation of both classes is rather poor, both as to numbers and variety.
