Brongersma, 11 ♂ ♂, 3 ♀ ♀, 1 young specimen. Zoological Museum, Amsterdam : Knysna, September 16—18, 1938, H. Engel, 10 ♂ ♂, 7 ♀ ♀, 1 young specimen. McLeay says: „Cleistotoma oculis magnis, testâ laevi haud pilosâ lateribus integris nec granulosis nec postice divergentibus, manibus brevibus; pedum pari tertio longiori, femoribus infra laevibus. Note. This species comes very near to the Cleistotoma Leachii of Milne Edwards; but differs from it in the surface being altogether smooth. The length is four lines." Krauss adds no further information and Stebbing states: „I do not know whether McLeay's species has been since recognised.,, The material, collected by Dr Brongersma and Dr Engel in South Africa, contains 33 specimens of a Cleistostoma species, collected at Knysna, probably Cleistostoma edwardsii McLeay. Gordon (1931, Journ. Linn. Soc. London, vol. 37, p. 550) gives a figure of the ♂ pleopods of Paracleistostoma leachi (Audouin). The pleopods of our species differ from these and from those of the two other species (depressum de Man and cristatum (Ortmann)) figured by Gordon. The ♂ pleopods of longimanum and microcheir (Tweedie, 1937, Bull.
