The lateral margins are armed throughout with a varying number of spines, very rarely more than thirty in number, and not arranged in series. There are no median setae. Of the thirteen species at present included in the genus Mysidopsis, only four have been recorded from southern waters, M. schultzei (Zimmer), M. similis (Zimmer), and M. major (Zimmer), all from shallow, coastal waters near Angra Pequena on the west coast of South Africa, and M. acuta Hansen from near the Falkland Islands. I am now able to add two new species, M. camelina and , to the genus Mysidopsis. Mysidopsis schultzei (Zimmer), 1912 (Fig. 37A-J) 1912 Paramysidopsis schultzei Zimmer, p. 5, figs.

Remarks. This species was founded by Zimmer for specimens taken in shallow water among sea- weed in Luderitz Bay near Angra Pequena. The animals were captured in quite considerable numbers together with two other new species, M. similis (Zimmer) and M. major (Zimmer). I have nothing to add to Zimmer's description of the species but, since his figures are rather small and the Discovery records are the first since he founded it, I give figures showing its salient features. Zimmer recorded. Please note that these images
