Station 41fir: Bernard harbour (outer harbour), surface net number 3, five minutes, August 1, 1915. One female in company with Cyclopina schneideri, Harpacticus uniremis and Harpacticus superflexus. 11. Eurytemora johanseni, n. sp. This species was taken in company with E. herdmani (Table II and Table XII)tfrom which it may be recognized externally by the length of the caudal furca. Whereas E. herdmani is longifurcate, the furca much exceeding the length of the anal segment, E. johanseni is brevifurcate, the furca and anal segment being subequal in length (Fig. 5).. Fig. 5. Eurytemora johanseni 9 • Dorsal view of hind-body. Description of female: total length 1-28 mm., anterior antennae as long as forebody; length of caudal furca 0-112 mm., of anal segment 0-104 mm., wings of genital segment small; mouth-parts as in E. velox. The fifth legs (p. 59) are four-jointed as in the type species; the unguiform process of the penultimate joint (Re 1), not exceeding Re 2 in length, is coarsely denticulated on its outer side; the right Re 2 (distal joint of the appendage) is larger than the left and crenulated on its inner border (Fig. 6)..
