CONFERVÆ The filamentous weeds of fresh water.
CONGLOMERATE A rock made up of fragments of rock or pebbles, cemented together by some other material.
COROLLA The second envelope of a flower usually composed of coloured, leaf-like organs (petals), which may be united by their edges either in the basal part or throughout.
CORRELATION The normal coincidence of one phenomenon, character, &c., with another.
CORYMB A bunch of flowers in which those springing from the lower part of the flower stalk are supported on long stalks so as to be nearly on a level with the upper ones.
COTYLEDONS The first or seed-leaves of plants.
CRUSTACEANS A class of articulated animals, having the skin of the body generally more or less hardened by the deposition of calcareous matter, breathing by means of gills. (Examples, Crab, Lobster, Shrimp, &c.)
CURCULIO The old generic term for the Beetles known as Weevils, characterised by their four-jointed feet, and by the head being produced into a sort of beak, upon the sides of which the antennæ are inserted.
CUTANEOUS Of or belonging to the skin.
DEGRADATION The wearing down of land by the action of the sea or of meteoric agencies.
DENUDATION The wearing away of the surface of the land by water.
DEVONIAN SYSTEM OR FORMATION A series of Palæozoic rocks, including the Old Red Sandstone.
DICOTYLEDONS OR DICOTYLEDONOUS PLANTS A class of plants characterised by having two seed-leaves, by the formation of new wood between the bark and the old wood (exogenous growth) and by the reticulation of the veins of the leaves. The parts of the flowers are generally in multiples of five.
DIFFERENTIATION The separation or discrimination of parts or organs which in simpler forms of life are more or less united.
DIMORPHIC Having two distinct forms. Dimorphism is the condition of the appearance of the same species under two dissimilar forms.
DIOECIOUS Having the organs of the sexes upon distinct individuals.
DIORITE A peculiar form of Greenstone.
DORSAL Of or belonging to the back.
EDENTATA A peculiar order of Quadrupeds, characterised by the absence of at least the middle incisor (front) teeth in both jaws. (Examples, the Sloths and Armadillos.)
ELYTRA The hardened fore-wings of Beetles, serving as sheaths for the membranous hind-wings, which constitute the true organs of flight.
EMBRYO The young animal undergoing development within the egg or womb.
EMBRYOLOGY The study of the development of the embryo.
ENDEMIC Peculiar to a given locality.
ENTOMOSTRACA A division of the class Crustacea, having all the segments of the body usually distinct, gills attached to the feet or organs of the mouth, and the feet fringed with fine hairs. They are generally of small size.
EOCENE The earliest of the three divisions of the Tertiary epoch of geologists. Rocks of this age contain a small proportion of shells identical with species now living.
EPHEMEROUS INSECTS Insects allied to the May-fly.
FAUNA The totality of the animals naturally inhabiting a certain country or region, or which have lived during a given geological period.
FELIDÆ The Cat-family.
FERAL Having become wild from a state of cultivation or domestication.
FLORA The totality of the plants growing naturally in a country, or during a given geological period.
FLORETS Flowers imperfectly developed in some respects, and collected into a dense spike or head, as in the Grasses, the Dandelion, &c.
FOETAL Of or belonging to the foetus, or embryo in course of development.
FORAMINIFERA A class of animals of very low organisation, and generally of small size, having a jelly-like body, from the Surface of which delicate filaments can be given off and retracted for the prehension of external objects, and having a calcareous or sandy shell, usually divided into chambers, and perforated with small apertures.
FOSSILIFEROUS Containing fossils.
FOSSORIAL Having a faculty of digging. The Fossorial Hymenoptera are a group of Wasp-like Insects, which burrow in sandy soil to make nests for their young.
FRENUM (pl. FRENA) A small band or fold of skin.
FUNGI
