 Barnard, 193 1, p. 427. 

 Occurrence: St. 51. Falklands. 1 ovig. $ 16 mm. 



Description. Integument indurated, sparsely punctate. Rostrum stout, about as 

 long as rest of head. Antero-lateral margin of head with two rather broad subquadrate 

 teeth separated by a narrow notch ; the lower tooth in the present specimen is somewhat 

 bent inwards over the bases of the mandibles. Eyes rather larger than in most of the 

 other allied species. Peraeon segment 7 with a pair of dorsal processes. Postero-inferior 

 angles of segments 1-4 rounded, of 5-7 subacute. Side-plates 1-3 rounded below;

4 rather blunt below, postero-inferior angle quadrate, lower posterior margin not 

 strongly concave. Pleon segments 1-3 each with paired dorsal processes, and a medio- 

 dorsal low keel, as in L. rigida, but that on segment 3 ending posteriorly in a sharp 

 tooth; postero-inferior angles of segments 2 and 3 with short points, the hind margin 

 on segment 3 serrate between the lower angle and the short lateral point; segment 4 

 with a rather high medio-dorsal keel, deeply notched in middle and ending posteriorly 

 in a short tooth; the dorso-lateral keels on segment 6 ending acutely. Telson apically 

 notched, the lobes sharply pointed. 



Antenna 1, inner distal margin of 1st joint with a short bidentate tooth not extending 

 beyond end of 2nd joint, with a short tooth at its base on upper inner apex; one strong 

 tubercle in middle of lower surface. Epistome transverse, with a median conical 

 tubercle proximally. Upper lip transverse, twice as broad as long, distal margin not
