(a) Endopod of a maxilla, possibly of copepod. (b) Endites of crustacean maxilla. (c) Distal segment of exopod of biramous trunk limb (see Figure 3a). (d) Fragment of crustacean maxilla or maxilliped. (e) Maxillary endite with jointed elements (arrowed). (f) Pair of maxillary endites, joint arrowed, of possible copepod. (g) A part of maxilla; arrow points to intrinsic muscle showing strands. (h) Distal part of antennary endopod of canthocamptid copepod. (i) Detail of geniculate setae of h. Scale bars, 50 μm.
