It may seem extraordinary that this northern and even arctic 
species should reappear, as Mr. A. O. Walker has determined, in 
antarctic waters. It has been taken by Mr. Vallentin at low 
water at spring tides on a sandy beach in Shallow Bay, 
Falkland Islands, Jan. 15,1911. The bright red pigment of the 
eyes lasts long in preservative fluid.

Chevreux’s Pontharpinia uncinatus is distinguished by the 
shorter wrist of the second gnathopods and the upturned postero- 
lateral angles of the third pleon segment, but in many respects, 
as the eminent French author observes, isa near neighbour of the 
present species. 
Locality. Falkland Islands, low water of spring tide.
