measured about 1-3 millim. {-^ of an inch) in length and had 

 a general resemblance to Licliomolgus. 



The antennules, which were imperfect, are moderately 

 short and composed of six (or seven) joints^ but only five 

 were present (fig. 15) ; the third joint is small, bat the others 

 are of moderate length. 



The mandibles and maxillae were not observed. 



Both pairs of maxillipeds are small ; the end joints of the 

 first maxillipeds are furnished on the upper aspect with two 

 moderately long setaj and a few minute spines ; one seta 

 springs from near the base of the joint, but the other is sub- 

 terminal ; both seta^ appear to be ciliated along one side, as 

 sliown by the drawing (fig. 17). The second pair of maxilli- 

 peds have the end joints armed with a small but stout terminal 

 claw, in addition to one or two small spines (fig. 18). 



All the four pairs of swimming-feet are moderately short 

 and stout and have both branches three-jointed and of nearly 

 equal length. 



In the first pair tlie first and second joints of the outer 

 branches are each furnished with a stout spine on the outer 

 margins, and there is also a seta on the inner margin of the 

 second joint, but not on the first ; the end joint bears four 

 spines on the outer margin and apex and four seta3 on the 

 inner margin. The first two joints of the inner branches 

 have each a seta on the inside margin^ while externally their 

 distal angles form each a small tooth-like process; the end 

 joint of the inner branches is armed with a stout subterminal 

 spine on its outer aspect and with five setje on its' inner 

 margin (fig. 19) ; all the setse appear to be plumose. 



The other three pairs are somewhat similar to the first, but 

 differ to some extent in the armature chiefly of the end joints. 

 In the second pair the only apparent difference is that the 

 end joints of the outer branches are furnished interiorly with 

 five instead of four set«, while the end joints of the inner 

 branches are each furnished with three spines on the outer 

 and three setse on the inner margin. The armature of the 

 third pair appears to be similar to that of the second. In the 

 fourth pair the second joint of the outer branches bears two 

 setse on the inner margin, while the end joint is armed with 

 three spines and three set^; the only difference observed in 

 the armature of the inner branches is in the end joints being 

 provided with three slender spines and two selge. 



The fifth pair are small and apparently only one-jointed 

 (fig. U).
