In order to complete this arrangement the outer maxillipeds, as indeed has long been known, bear a projecting ridge furnished with a dense fringe of hairs, which commences in front near their median line and passes backwards and outwards to the hinder angle of the buccal frame.
It seems to me hardly doubtful, that the ramified hollow filaments are themselves nothing but the cement-ducts converted into nutritive roots, and that it is just in consequence of the development of this new source of nourishment, that the cirri and buccal organs are in the highest degree aborted.
"We get the inside beak over the palatal roots and the cow-horn beak over the buccal roots that's the roots on the outside, you see. Then we close the forceps, and that breaks right through the alveolus that's the part of the socket in the jaw, you understand." At another moment he told her of his one unsatisfied desire. "Some day I'm going to have a big gilded tooth outside my window for a sign.
With the further development, assisted by natural selection, of the roots embracing the intestine of the host and spreading amongst its hepatic tubes, the introduction of nourishment through the mouth and all the parts implicated in it, such as the whirling cirri, the buccal organs, and the intestine, gradually lost their importance, became aborted by disuse, and finally disappeared without leaving a trace of their existence.
While so many others, joyful banqueters, fly from flower to flower, unrolling their spiral trunks to plunge them into honeyed blossoms, this incomparable ascetic, completely freed from the servitude of the stomach, has no means of restoring its strength. Its buccal members are mere vestiges, useless simulacra, not real organs able to perform their duties.
This Lepadide, which lives upon Sharks in the North Sea, seems, in fact, to be in the best way to lose its cirri and buccal organs in the same manner. The widely-cleft, shell-less test is supported upon a thick peduncle, which is immersed in the skin of the Shark. Darwin looked in vain for cement-glands and cement.
In the cavities of the nose is located the sense of smell, while the buccal cavity, or mouth, is the site of the sense of taste, and plays besides an important part in the first act of digestion and in the function of speech. The bones of the face are: 34. Bones of the Face. The superior maxillary or upper jawbones form a part of the roof of the mouth and the entire floor of the orbits.
The larva still continues like a Nauplius, as the three anterior pairs of limbs represent rowing feet; at the next moult it is converted into the youngest Cyclops-like state, when it resembles the adult animal in the structure of the antennae and buccal organs, although the number of limbs and body segments is still much less, for only the rudiments of the third and fourth pairs of natatory feet have made their appearance in the form of cushions fringed with setae, and the body consists of the oval cephalothorax, the second, third, and fourth thoracic segments, and an elongated terminal joint.
Food and drink, as have been mentioned, markedly influence the odor of an individual, and those perpetually addicted to a special diet or drink have a particular odor. Odor after Coitus. Preismann in 1877 makes the statement that for six hours after coitus there is a peculiar odor noticeable in the breath, owing to a peculiar secretion of the buccal glands.
But what is most remarkable is, that they now appear under two different forms. The terminal setae of the second pair of antennae project between the cheliferous feet. Buccal region of the same from below; lambda, labrum. Head of the rarer form of the male, magnified 25 times. In the first place, and before inquiring into its significance, I will say a word upon this fact itself.
