distinguished by being furnished at the middle with a wreath of long, stiff secondary bristles, 

 contrary to what is usual in bristles of this group. The c- and d-bristles are of about the same 

 type as each other, with close long, soft hairs at the middle and short hairs distaUy; both are 

 moderately long, the former somewhat shorter than the latter (about the same as in figure 22 

 of C. (Vargula) norvegica). The two lobes of the third joint (fig. 19, c? = ?) are of moderate 

 size, like the end joint. The inner lobe of the third joint has distally two moderately long bristles 

 with short hairs or bare; proximally-posteriorly it has a single bristle, which is somewhat shorter 

 than the distal ones and which has long hairs at the middle and short ones distally. The outer 

 lobe of this joint has two moderately long distal bristles with short hairs or almost naked. The 

 end joint is furnished distally with four moderately long bristles somewhat different in lengtli 

 and with short hairs. The proportion between all the bristles of the two distal exopodite joints 

 seems to be fairly constant and is shown in the accompanying figure. Pilosity: The outer 

 lobe of the third exopodite joint and the end joint are partly furnished with soft hairs placed 

 close together. 



Sixth 1 i m b (fig. 20) : — P r o t o p o d i t e : The first endite has one rather long 

 and powerful distal bristle, furnished with a few oblique wreaths of long, stiff secondary bristles 

 and two short, plumous medial bristles. The second endite has two rather long and powerful 

 distal bristles, of which the dorsal one is somewhat shorter than the other; both are furnished 

 at the middle with long, stiff secondary bristles and with short hairs distally; this endite has, 

 in addition, two short, plumous medial bristles. The third endite has two rather long and 

 powerful distal bristles, furnished at the middle with one or a few wreaths of long, stiff secondary 

 bristles and with short hairs distally; between these two bristles there is a short and somewhat 

 plumous bristle. The epipodial appendage of the protopodite is represented by 

 two rather short bristles with short hairs. Exopodite: The endite of the first joint has 

 two bristles, one rather long and powerful, of the same type as the long distal bristles on the 

 preceding endite, the other rather short, with long hairs at the middle and short ones distally. 

 The second joint has from six to eight moderately long bristles, all of which are situated very 

 near the ventral edge; there is a rather pronounced gap between the posterior and the other 

 bristles. The two posterior bristles have long, soft hairs right out to their points; the bristle 

 that is situated nearest to them has soft, long hairs at the middle and short hairs distally; the 

 other three or five bristles are furnished at the middle with long, stiff secondary bristles, arranged 

 in most cases in two very distinct wreaths; distally they have short hairs. Pilosity: On the 

 inside this limb is furnished with fine, short hairs, placed close together; the second exopodite 

 joint has laterally a series of short stiff hairs along the ventral margin. 



Seventh limb (fig. 13): — This is weak, almost of a larval structure and very 

 short comparatively, being only about a third of the length of the shell. It is furnished with 

 eight cleaning bristles; six of these, three dorsal and three ventral ones, are situated very close 

 together distally, the two remaining ones are situated somewhat more proximally, one on the 

 dorsal and one on the ventral edge. The bristle situated most distally, both among the dorsal 

 as well as among the ventral ones, is comj^aratively long, the others are moderately long or 

 rather short. The cleaning bristles are furnished with three or four bells cut off transversally
