found in this family. It is small, slender, and delicate, reaching only 

 about half-way along the inner margin of the outer lobe, and there is no 

 sign of the usual two plumose setae, the rounded extremity bearing only 

 a few very fine minute setae. The palp is either absent altogether or 

 is represented only by a small mark on the outer convex margin ; but 

 though this corresponds in position and shape with the minute palp 

 found in many species of Orchestia, it does not project beyond the margin 

 of the outer lobe, and is apparently fused with it. 



The second maxilla (fig. 12) is of normal shape, being formed of 2 

 subequal delicate lobes, each with the usual terminal fringe of long setae ; 

 a few finer setae are found on the inner margin of the inner lobe and the 

 outer margin of the outer lobe ; there is no sign of the special plumose 

 seta bounding the apical fringe of spines of the inner margin which is 

 mentioned by Stebbing in his definition of the family Talitridae.

The maxillipeds (fig. 13) present one or two special characters, but on 

 the whole are similar to those of species of Hyale. The outer and inner 

 lobes are of nearly the same length, the inner lobe bearing at its truncate 

 extremity 2 or 3 short blunt teeth with 1 or 2 longer dentate spines ; the 

 inner margin of the lobe is free from setae except near the distal end. The 

 outer lobe is slightly broader than the inner, the outer margin being 

 convex, and its inner margin supplied with numerous spinules. The merus, 

 or first joint of the palp, has its outer angle much produced so as to reach 

 fully as far as the end of the carpus ; its inner distal margin is much 

 hollowed for the reception of the carpus, which extends farther towards 

 its base on the inner tlian on the outer side. The carpus and propod are 

 subequal and somewhat oval in shape, with the inner margins strongly 

 convex and bearing a fringe of long spines ; the propod in addition has 

 a distinct transverse row of long spines near its distal end. The dactyl
