After an examination of 4 South African specimens and their com- 

 parison with Plymouth specimens of L. spinicarpa (Abildg.), I have 

 come to the conclusion that L. miersi Stebb. must be added to the 

 synonymy of the former species already given by Chilton. 



Although in the South African specimens the 3rd joint of the 

 mandibular palp is somewhat shorter than in Plymouth specimens 

 and Sars' figure (I.e. pi. 100), it is not so extremely short as in the 

 Challenger specimen. It is in fact somewhat variable even among 

 the 4 South African specimens. The other character by which miersi 

 is distinguished from the typical spinicarpa, namely, the relative 

 lengths of the ultimate and penultimate peduncular joints of the 

 2nd antenna, is also somewhat variable; in the South African specimens 

 the ultimate joint varies in length from little more than ~ to |. the 

 length of the penultimate. Also the strength of the denticulations on 

 palm of 2nd gnathopod varies. 



Length : 12 mm. (an ovigerous $ from St. James : 4 niin.). 



Colour : The single specimen collected by myself at low-tide was 

 unfortunately not observed amongst numerous other amphipods until 

 the colours had faded.
