Reconstruction of front part of Gigantocypris from the level of the adductor tendon viewed from behind to show the body retractor system and its relation to the endoskeletal system. The anterior hypostomal apodemes lie in the plane of the paper. The antenno-labral apodemes which are at right angles to the latter are thus mainly hidden by the adductor tendon. The setal armature of the mouthparts has been omitted. a. 1, antennule; , antenna; anterior hypostomal apodeme; antenno-labral apodeme; adductor tendon; gn. gnathobase of mandible; lab. labrum; m. mouth; adductor muscle; mdb. mandible; dorso-ventral body retractor muscle; nauplius eye; oes. oesophagus \ paired eyc;st. stomach. The caudal furca has its own system of sclerites which, as I have already mentioned, are quite separate from the rest of the skeleton. The muscles attached to the caudal furca which give it stability are the dorsal longitudinal series which attach directly to the shell at the side of the heart (Fig. 9) and a powerful pair of muscles which run for- wards, and after attaching to the thin body wall between the caudal furca and the hinder margin of the first trunk limb, continue forwards as a group of three muscles on either side, to attach to the adductor tendon and to the apodeme between maxillule and maxilla (Fig. 6). 4-2.
