(n.) A genus of decapod Crustacea, including some of the most
common shore crabs of Europe and North America, as the rock crab, Jonah
crab, etc. See Crab.
(n.) The fourth of the twelve signs of the zodiac. The first
point is the northern limit of the sun's course in summer; hence, the
sign of the summer solstice. See Tropic.
(n.) A northern constellation between Gemini and Leo.
(n.) Formerly, any malignant growth, esp. one attended with
great pain and ulceration, with cachexia and progressive emaciation. It
was so called, perhaps, from the great veins which surround it,
compared by the ancients to the claws of a crab. The term is now
restricted to such a growth made up of aggregations of epithelial
cells, either without support or embedded in the meshes of a trabecular
framework.
