BY THE REV, T. R. R. STEBBING ON 
variety of synonyms, including Pfeffer’s Podocerus ingens, which 
attains a length of 26 mm., Walker’s Hemijassa goniamera and 
Jassa wandeli Chevreux. In 1913 Chevreux points out that, 
though the adult male of his species proves to have second 
gnathopods very similar to those of J. falcatus, it is nevertheless 
distinguished among other things by a more elongate carpus of 
the first gnathopods, the comparatively narrow second joint of 
the fourth and fifth perzopods in which the hind margin is 
almost straight, and by the less acute apex of the telson. In all 
these respects it is distinct from the little specimen here recorded, 
which has a length of only 3mm.; the antennz are well furnished 
with long sete, and the second joint in the third, fourth, and 
fifth pereopods has a very decidedly convex margin. 
Locality. Stanley Harbour, among seaweed at low water of 
spring tide. 
Another specimen in the collection, which J should be inclined 
to identify with Jassa ingens (Pfeffer), measures 8°5 mm. in 
length. It has the second joint of the very elongate second 
enathopod much curved, and the tooth of the large sixth joint 
irregular in shape, as described and figured by Pfeffer.

The figures and description of the female supplied by Dr. S. J. 
Holmes leave no doubt that Mr. Vallentin’s specimens belong to 
this species. Holmes gives the length as 3-4 mm. Paulmier 
gives it as 5 mm., probably with reference to a male specimen 
which he figures in full. The Falkland Island specimens, collected 
during low water of spring tides, measure only 3 mm. It is
