gap between the posterior bristles and the otlnMs. The two posterior ones arc rather long, 

 with long, soft haii"s right out to their points. Oi the others some are rather long, others are 

 of moderate lengtli or more or less short. iSome of them have long hairs at the middle 

 and shcnt haii-s liistally; the long hairs are not or arc only slightly arranged in wreaths; 

 on the posterior ones of these bristles they are soft, on the anterior ones somewhat stiffer. The 

 other bristles, in most cases the shorter ones, have only (piite short hairs. Pilosity: This limb 

 is smooth both i>n the outside and tlic inside, but has a series of unusually hmg and powerful 

 hairs along the posterior part of the ventral margin of the second exopodite joint. 



Seventh limb (figs. 17, 18): — This is of nu)derate length, slightly longer than 

 half the length of the shell. Cleaning bristles: Distally, situated very close together, there are 

 ten bristles, five dorsal and five ventral ones; of these — both among the dorsal and the ventral 

 ones — the most distal one is rather short, tlie next distal one relatively long and the rest 

 decrease somewhat in length the more proximally they are situated, the proximal one being 

 rather short. At some distance proximally of these there are four more bristles, two on each 

 side; these are rather long or of moderate length. The cleaning bristles are furnished with 

 from three to eight bells, cut off transversally distally; the tongue of the distal bell is also cut 

 off transversally distally. (Of about the same type as is shown in fig. 25 of C. (Vargida) nor- 

 cegica.) Proximally of the bells the bristles are bare. The end comb consists of a long, very strong, 

 bare central distal tooth, somewhat bent inwards and distally pointed, and three considerably 

 shorter distal teeth and three proximal teeth on each side of the former. The distal one of the 

 three last-mentioned distal teeth is somewhat longer than the two others and is distally pointed, 

 the two others are rounded distally. The dorsal wall of the cavity, dorsally close to the end 

 comb, consists of two somewhat S-shaped chitinous plates, situated by the side of each other, 

 cut abruptly off dorsally and furnished there with a number (about ten) of fine, short teeth. 



Furca (fig. 8): — This has eight comparatively powerful and straight claws, all well defined 

 from the lamella, except nos. 2 and 4, which are completely joined to it. The claws decrease fairly 

 uniformly in length the more proximally they are situated, except no. 3, which is only about as 

 long as and considerably weaker than no. 4. Proximally of the claws the furca has short hairs. 



Upper lip (fig. 7) : — The upper glandular field is narrow, almost crest-shaped and has 

 about nine or ten moderately large pegs (the mouths of the glands), of which only a few of the 

 ventral ones are paired. The paired ventral glandular fields are also almost crest-shaped and 

 about as large as the unpaired dorsal one; they have a rather small number of moderately large 

 pegs, a couple of the most posterior of which being somewhat higher than the others. The protuber- 

 ance situated dorsally of the upjDcr lip is rather large, and has a single point, somewhat rounded. 



The median eye is rather well developed. The rod-shaped organ is missing? 

 (broken off?). 



The male is unknown. 



ypc specimen. Remarks: — The type specimen of this species is a female with large eggs in its ovaries. 



Apart from this specimen I haA^e only investigated a larva, presumably in the last larval stage. 

 This larva agreed in practically every detail with the type specimen.
