 was 18 — 21, the distal one of which was exceedingly short. The .sensory filaments on all the 

 bristles of the seventh and eighth joints are bare. The simple sensory bristles d and e are 

 subequal and almost as long as the third to the eighth joints. Pilosity : The second and third joints 

 are only weakly furnished with hairs, the rest of the joints seem to be quite smooth. 



Second antenna: — Protopodite: Length about 2 mm. in specimens 

 about 6,5 mm. long. The medial-distal bristle is almost completely reduced and is considerably 

 shorter than the proximal bristles on the first joint of the endopodite. E x o p o d i t e (fig. 11): 

 The first joint is somewhat longer than the total length of all the following joints; the second 

 joint is about as long as the total length of the third and fourth joints, the third is about equal 

 to the total length of the fourth and fifth or a little shorter, the remaining joints are subequal. 

 The bristle of the second joint is very weak, quite bare and only about half the length of the 

 third joint. The proportion between the length of the long natatory bristles and the total length 

 of the exopodite is about three to two. The former have very wide natatory hairs (cf. 

 fig. 12), which issue along the whole length of the bristle and even near the point where the 

 bristle is attached. The end joint has four bristles, of which even the two dorsal ones are 

 well developed; the shortest dorsal one, which, like the three others, has wide natatory 

 hairs situated close together along its whole length, is about as long as the total length of the 

 eight distal exopodite joints. The third to the ninth joints have short, conical and almost 

 reduced basal spines; that of the end joint especially is extremely weak, sometimes even difficult 

 to verify with certainty; the basal spines are sometimes provided with fine secondary teeth. The 

 endopodite (fig. 13) is small, verruciform and more or less distinctly two-jointed. Proximally 

 on the first joint there are four subequal, moderately long, bare or almost bare bristles. Distally 

 on this joint there is a single bristle, in most cases somewhat shorter than the four proximal 

 ones and of the same type as these. The bristle of the end joint is rather long, about a c^uarter 

 of the length of the protopodite of this limb. 



^landible: — Protopodite: The endite on the coxale has over the greater 

 part of the dorsal-lateral and dorsal-medial sides only a few short and rather weak spines; 

 ventrally and distally, on the other hand, the spines are numerous and rather long and powerful. 

 Distally it is weakly bifurcated; the two points are a good deal more powerful than the other 

 spines and are furnished with a few secondary spines; between these two points there is a low
