The chelophores bear their chela, or "hand," on a stalk or scape ; the ambulatory legs are constituted of three coxal joints, a femur, two tibial joints, a tarsus, and a propodus, with its claws, and with or without auxiliary claws.

. The Cambridge natural history. Zoology. BODY AND LIMBS SOS or " chelophores," the second or " palps," the third, the false or " ovigerous " legs, and the first of the four pairs of " ambulatory " legs. The chelophores bear their chela, or "hand," on a stalk or scape ; the ambulatory legs are constituted of three coxal joints, a femur, two tibial joints, a tarsus, and a propodus, with its claws, and with or without auxiliary claws. The Body.—The trunk with its lateral processes may be still more compact than in Pycnogonum, still more attenuated than in Nymplion. In a few forms ( Pallene, Ammothea, Tanystylum, Colos- sendeis) the last two, or even more, segments of the trunk are. A B C Fig. 265.—A, Colossendeisprohoscidea, Sabine, Britain ; B, Ammothea echinata, Hodge, Britain ; C, Plioxichilus spinosus, Mont., Arctic Ocean. (The omitted.) more or less coalescent. In Rliyncliothorax the cephalic segment is produced into a sharp-pointed rostrum that juts forward over the base of the proboscis. The whole body and limbs may be smooth, tuberculated, furnished with scattered hairs, or some- times densely hispid. The proboscis varies much in shape and size. It may be much longer or much shorter than tne body, cylindrical or tumid, blunt or pointed, straight or ( Decolopoda) decurved; usually firmly affixed to the head and pointing straight forwards; sometimes {Eurycide, Ascorhynchus) articulated on a mobile stalk and borne deflexed beneath the body. Chelophores.—The first pair of appendages or chelophores are wanting in the ' adult Pycnogonum, PJioxicJiilus, PJiynclio- thorax, and Colossendeis} ' Hoek, Ohall. Rep. p. 15, mentions a specimen of Colossendeis gracilis, Hoek,.
