Pleon in lateral view. Description Exoskeleton very thin. Carapace almost circular (when compressed), apparently attached to the body only in the anterior region. No sign of a medio-dorsal carina. Rostrum short, triangular. Antero-lateral corner of carapace bearing one small acute spine; occasionally a second or even a third tiny spine may be seen posterior to the antero-lateral spine. Anterior margin of carapace slightly concave. A faint longitudinal suprabranchial suture, stretching from the region of the anterior margin to the posterior margin may be seen on the carapace of some specimens. Posterior margin of carapace dorsally concave. Abdomen usually under thorax, consisting of five segments plus telson. (A reduced first segment, hidden by the posterior part of the thorax and carapace may be present.) Pleura of abdominal segments apically acute, apices directed posteriorly. Antennule with 3-segmented peduncle, basal segment equal in length to two distal segments together, peduncle extending beyond antennal scaphocerite. Inner fiagellum slightly shorter than outer, latter only slightly longer than peduncle. Antennal scaphocerite elongate-oval, reaching to end of second segment of antennular peduncle. Single fiagellum reaching posteriorly to level of posterior carapace margin. Eyestalks slender, situated dorsal to the antennae. Epistome ventral, elongate-oval, separating the mandibles. Position and structure of the mouthparts uncertain. An elongate slender mandibular palp Fig. 3. Notocaris tapscotti. (All figures natural size.) A-D. Laingsburg. E. Ratelklip, Calvinia. F-I. Kimberley. A. Specimen showing ventral sternites and eyestalks. B-D. The Laingsburg specimens preserved in dark grey shale, appear to have a 'smear' of white material surrounding and obscuring the fossil and its impressi
