The lungless mountain stream salamanders of North America (Pletho- dontidae) apparently present a parallel adaptation, since other families of salamanders also have a few lungless mountain brook Organs of attachment of the most diverse kinds are especially char- acteristic of the animals of this environment. The claws of the legs of all water mites and insect larvae are strongly developed. Flatworms, may-fly nymphs, and snails have adherent surfaces, which are much larger in the snails of this region than they are in land snails of equal size. The leeches attach themselves by means of sucking cups, the posterior end of the larva of Melusina, a biting gnat, bears sucking plates whose power of attachment is increased by bristles, and on the flat, sole-like under surface of the larvae of other midges of the fam-.
