The crabs and other crustaceans on which it lives from which circumstance it obtains its name are found on low marshy soils, in the neighbourhood of which these species exist. It has no true pouch, and the mother, therefore, while her young are in their infancy, carries them on her back. From this circumstance the name of dorsigerus, or back-bearing, has been given to it.
The women wear a small rump basket tied around the waist in which they carry their lunch to the rice sementeras, and once or twice each week they bring home from a few ounces to a pound of small crustaceans. One variety is named song'-an, another is kit-an', a third is fing'-a, and a fourth is lis'-chug. They are all collected in the mud of the sementeras. Vegetal production
As I say, I had only just returned from Java with a valuable collection of undescribed isopods an order of edriophthalmous crustaceans with seven free thoracic somites furnished with fourteen legs and I beg my reader's pardon, but my reader will see the necessity for the author's absolute accuracy in insisting on detail, because the story that follows is a dangerous story for a scientist to tell, in view of the vast amount of nonsense and fiction in circulation masquerading as stories of scientific adventure.
In order of time, fish would naturally come later than the lower invertebrata; both as being less likely to have their ova transported across the waste of waters, and as requiring for their subsistence a pre-existing Fauna of some development. They might be expected to make their appearance along with the predaceous crustaceans; as they do in the uppermost Silurian rocks.
He expected to find Crustaceans also, more nearly approaching the ancient Trilobites than those now living on the surface of the globe; and among Radiates he looked for the older forms of sea-urchins, star-fishes, and corals. Although the collections brought together on this cruise were rich and interesting, they gave but imperfect answers to these comprehensive questions.
Before the "Pilgrim's" sails had been brought aback, she had drawn a little nearer to the place where the jubarte continued to signal its presence by jets of vapor and water. The jubarte was all this time swimming in the middle of the vast red field of crustaceans, opening its large mouth automatically, and absorbing at each draught myriads of animalcules.
We will content ourselves, then, without further pretension to science, with modestly examining the last transformations of our pet machine in the principal groups of the inferior animals; of which groups I will now tell you the names in their proper order. They are as follows: Insects, Crustaceans, Mollusks, Worms, and Zoophytes.
I have frequently, with my own eyes, seen more than a thousand of these small bodies of birds, hanging down on the seashore from one piece of timber, enclosed in shells, and already formed." Here, again, our author is speaking of the barnacles themselves, with which he naturally confuses the geese, since he presumes the Crustaceans are simply geese in an undeveloped state.
The hermit-crab was once equipped with a hard shell and with as good means of locomotion as other crabs. But instead of courageously following the hardy life of other crustaceans it formed the bad habit of taking up its residence in the cast-off shells of mollusks. This made life easy and indolent. But it paid the price of all shirking.
Dana believes, that in ordinary Crustaceans, the abortion of the segments with their appendages almost always takes place at the posterior end of the cephalothorax." The original development of the Malacostraca starting from the Nauplius, or the lowest free-living grade with which we are acquainted in the class of Crustacea, is now-a-days nearly effaced in the majority of them.
