Homarns vulgaris, the Lobster, isvery like the Crayfish, but is much larger, and livesin the European seas; a nearly allied species is foundon the coast of North America. The Lobster iscaught in baskets, into which it creeps during thenight. Its importance as an article of food may be. estimated by the fact that about 13 millions are annu-ally consumed in Europe and in North America. Fig. e. Paliimrus vulgaris, the Spiny Lobster,represents the family Loricata, in which the fivepairs of legs do not end in pincers. The outer an-tennae are longer than the body, and their basaljoints are thick and spiny. It is common in theEuropean seas, and sometimes attains a weight pounds. Its flesh is more esteemed on the coastsof the Mediterranean than in England. In the family Ca7-idinidcE, which includes theShrimps and Prawns, the cephalothoracic shield is generally produced ^ into a large beak,and the first 2 or3 pairs of legs fre-quently end in smallpincers.
