Twenty-nine euphausiid species were collected during the three cruises of the S.A.S. NatAI in 1958. Of these only Stylocheiron microphthalma had not previously been taken in South African waters. The commonest euphausiid represented in the collection is a Iarval series which is provisionally linked with Euphausia recurva or E. mutica. The vertical and horizontal distribution of each species is recorded and seasonal and latitudinal variation discussed. Stylochelron suhmii, S. microphthalma and Thysanopoda tricuspidata are proposed as indicators of Agulhas Current water and Nyctiphanes capensis and Euphausia lucens as indicators of water not of Agulhas Current origin. The largest number of euphausiids was found off Port Elizabeth during both summer and winter.
