I. South African Crustacea (Part IV. :;: ). By the Eev. THOMAS 

 E. E. STEBBING, M.A., F.E.S., F.L.S., F.Z.S. 



THE scope of the present contribution is enlarged by including 

 several species of Amphipoda a group of which very few members 

 have been hitherto recorded from South African waters. Seven 

 of the species now noticed claim to be new, one of them even 

 demanding the institution of a new genus. But, as in many other 

 groups of Crustacea, so in this, the novelty of the characters is less 

 striking than the close general relationship between the forms found 

 here and others earlier known and described from many very remote 

 localities. In regard to the new species of the curious genus 

 Trischizostoma, it is desirable to call attention to the important 

 contemporary discussion of that genus by Mrs. E. W. Sexton, 

 working at the Plymouth Laboratory. As an example of widely 

 ranging genera the coincidence may be noted that the description 

 of the remarkable prawn, Leontocaris paulsoni, from the Cape, had 

 only been a few months published in Part III. of this series when 

 Mr. Stanley W. Kemp was able to announce a second species of 

 this highly specialised genus from the west coast of Ireland, taken 

 at a depth of 500 fathoms in lat. 53 N., outside the " Porcupine 

 Bank." 



Besides the numerous specimens due to Dr. Gilchrist's "Marine 

 Investigations," the present report deals with a large collection sub- 

 mitted to me from the Durban Museum. When sending this valuable 



* The other three Parts have been published in " Marine Investigations in 

 South Africa."
