They are encased in armour of shell, and this has given to them and their relations the name of Crustaceans, or Crusty creatures, because what bones they have are outside, not hidden beneath the flesh.
Monday, August 17. I am trying to recall the peculiar instincts of the monsters of the preadamite world, who, coming next in succession after the molluscs, the crustaceans and le fishes, preceded the animals of mammalian race upon the earth. The world then belonged to reptiles. Those monsters held the mastery in the seas of the secondary period.
At first miserable and scanty tribes had wandered along its coasts seeking their food from the crustaceans drawn from the waves a life similar to that of the rudimentary people that Ferragut had seen in the islands of the Pacific.
In our discussion on embryology, we shall see why such characters are so valuable, on the view of classification tacitly including the idea of descent. Our classifications are often plainly influenced by chains of affinities. Nothing can be easier than to define a number of characters common to all birds; but in the case of crustaceans, such definition has hitherto been found impossible.
"Hold!" said Captain Hull. "That is whales' food. Mr. Benedict, a fine occasion to study this curious species of crustacea." "Phew!" from the entomologist. "How phew!" cried the captain. "But you have no right to profess such indifference. These crustaceans form one of the six classes of the articulates, if I am not mistaken, and as such " "Phew!" said Cousin Benedict again, shaking his lead.
Did you never hear of the way soldiers used to arm themselves for the fight in old times? in plates of jointed armour?" "Yes, I know they did." "Well these fellows are armed just so only they do not put on steel or brass, but hard plates of bone or horn that do exactly as well, and are jointed just as nicely." "And those are Crustaceans?" "Those are Crustaceans." "And was this thing armed so?"
Yet all these organs, serving for such widely different purposes, are formed by infinitely numerous modifications of an upper lip, mandibles, and two pairs of maxillae. The same law governs the construction of the mouths and limbs of crustaceans. So it is with the flowers of plants.
Heterocerus, stridulation of. Hewitt, Mr., on a game-cock killing a kite; on the recognition of dogs and cats by ducks; on the pairing of a wild duck with a pintail drake; on the courtship of fowls; on the coupling of pheasants with common hens. Hilgendorf, sounds produced by crustaceans. Hindoo, his horror of breaking his caste.
Powrie to be the eggs of crustaceans, which is highly probable, for they have not only been found with Pterygotus anglicus in Forfarshire and Perthshire, but also in the Upper Silurian strata of England, in which species of the same genus, Pterygotus, occur.
"I am going to follow the contour of these reddish waters, so as to keep to the leeward." "Good!" said Captain Hull. "Boys, as little noise as possible in rowing." The oars, carefully muffled with straw, worked silently. The boat, skilfully steered by the boatswain, had reached the large shoal of crustaceans.
