As she approached the thing it backed slowly away upon its spider legs. She noticed that its chelae waved slowly to and fro before it as it backed, backed, backed, through the round aperture in the wall. Must she follow it there, too? What new and nameless horror lay concealed in that hidden chamber? No! she would not do it.
When the mother returned there were but five babies and a great spider-like creature, which she immediately sprang to attack only to be met by powerful chelae which seized and held her so that she could not move. Slowly they dragged her throat toward a hideous mouth and in a little moment she was dead.
As the chelae of Crustaceans resemble in some degree the avicularia of Polyzoa, both serving as pincers, it may be worth while to show that with the former a long series of serviceable gradations still exists.
In the center of the chamber a headless body lay upon the floor a body that had been partially devoured while over and upon it crawled a half a dozen heads upon their short, spider legs, and they tore at the flesh of the woman with their chelae and carried the bits to their awful mouths. They were eating human flesh eating it raw!

I will take it," and without further discussion it commenced to crawl up the front of the headless body, using its six short, spiderlike legs and two stout chelae which grew just in front of its legs and strongly resembled those of an Earthly lobster, except that they were both of the same size. The body in the meantime stood in passive indifference, its arms hanging idly at its sides.
During the Mysis-period, the auditory organs in the basal joint of the anterior antennae are formed; the inner branches of the first three pairs of feet are developed into chelae and the two hinder pairs into ambulatory feet; palpi sprout from the mandibles, branchiae on the thorax, and natatory feet on the abdomen. The spine on the labrum becomes reduced in size.
But, as far as structure is concerned, I can see no similarity between tridactyle pedicellariae and avicularia. The latter resembles somewhat more closely the chelae or pincers of Crustaceans; and Mr. Mivart might have adduced with equal appropriateness this resemblance as a special difficulty, or even their resemblance to the head and beak of a bird. The avicularia are believed by Mr. Busk, Dr.
