Caridea. -Tribe 4. "We will novsr consider the Shrimps and Prawns, since in them occurs the most complete metamorphosis found in the Deca- poda. The Peneidea are dis- tinguished from the ordinary Prawns and Shrimps (Caridea) by having the first three instead of the first two pereiopods chelate. The genus Peneus affords several species which are of commercial value as objects of food; the edible Prawns of the Mediter- —Willemoesia inornata, X i. ranean belong to this genus, while (From a figure prepared tor Pro- . -vt i n fessor Weidon.) in the JS orth Sea two 01 the Caridea, viz. the Shrimp, Crangon vulgaris, and the Prawn, Palaemon serratus, are the forms very commonly eaten. Both subdivisions are well represented in the deep sea fauna from all parts of the world. Glypliocrangon spinidosa (Fig. 110, p. 164) is a deep sea Shrimp with eyes that have lost their pigment, and with the body covered with spines, while the last abdominal segment is fused witli the telson to form a sharp bayonet - like process at the hind end of the body.
