' Tariftv of synonyms, inclutlina; Pfeffer's Podoccrus iiigens, which 

 attains a length of 26 mm., Walker's Hemijassa goniamera and 

 Jassa icandeli 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 perseopods in which the hind margin is 

 almost straight, and hy 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 3 mm.; theantennaj are well furnished 

 with long setpe, and the second joint in the third, fourth, and 

 fifth peri>iopods has a very decidedly convex margin. 



Locality. Stanley Hai'bour, among seaweed at low water of 

 spring tide. 



Another specimen in the collection, which I should be inclined 

 to identify with Jassa mgens (Pfefler), measures 8*5 mm. in 

 length. It has the second joint of the very elongate second 

 gnathopod much curved, and the tooth of the large sixth joint 

 irregidar in shape, as described and figured by Pfeft'er.

 The figures and description of the female supplied by Dr. S. J. 

 Holmes leave no doubt that Mr. Yallentin's specimens belong to 

 this species. Holmes gives the length as 3-4 mm. Paulmier 

 gives it as 5 mm., probaol}' witli i-eference to a male specimen 

 which he figures in full. The Falkland Island specimens, collected 

 during low water of spnn<r tides, measine onlv 3 mm. It is
