is a tendency to a slight emargination at the apex, and in one species, M. angusta G. O. Sars, there is 

 a small unarmed notch or cleft. 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 M.falklandica, 

 to the genus Mysidopsis.

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
