DISCOVERY REPORTS 



the foliaceous rami appear to be set in a vertical plane, it may be assumed that in life 

 they are capable of considerable lateral movement, and even in the preserved state the 

 inner ramus can be pushed down so as to fit into the infolded outer margin of the outer 



ramus. 



The discovery of the 3 will be awaited with great interest. During the winter cruise 

 of the ' Discovery II ' in South Africa in 1930 Dr Kemp instituted a special search for 

 this interesting little Amphipod, but without any success.

 their lower margins, 3 much smaller than 2 or 4, the latter larger than either 1 or 2, 

 ovate, shallowly excavate on hind margin proximally; side-plates 5-7 longer than deep, 

 5 feebly bilobed, the lobes subequal, 6 with slightly concave lower margin. Pleon seg- 

 ments 4 and 5 slightly gibbous posteriorly, but not dentiferous, the posterior margin 

 minutely denticulate. Postero-inferior angles of pleon segments 1-3 rounded, the 

 angle in segments 2 and 3 feebly crenulate. Telson as here figured, in course of 

 regeneration. 



Antenna 1 slender, 2nd joint longer and more slender than 1st, 3rd shorter than 1st,
