bristle, counting from inside, which iu that case is quite bare. The three outer ones are pectinated 

 distally, the one situated nearest to them, which in most cases is somewhat more powerful 

 than the rest, is either bare distally or has a few secondary teeth; the long one of the two inner 

 bristles is tri-furcated distally, the small one has short hairs or is bare distally. The third endite 

 has also seven distal bristles, rather strong and of moderate lengths, those situated distally (in 

 the middle) being somewhat shorter than the others. Of these the inner one has short, fine 

 hairs, aU the rest are furnished at the middle with rather sparse, long, stiff secondary bristles; 

 the two outer ones are pectinated distally, the rest seem to be smooth distally. The proximal 

 bristle on the outside of the third endite has short, fine hairs and is not quite as long as the 

 outside of this process. The dorso-distal bristle on the coxale is not quite as long as the outer- 

 distal bristle on the third endite. On the boundary between the basale and the first endopodite 

 joint there are three bristles. Of these the one that is fixed close to the exopodite is somewhat 

 longer than the last-mentioned branch and is furnished at the middle with a few long secondary 

 bristles, distally it is bare or has short fine hairs. The one at about the middle of the inside 

 of the palp is about a third of the length of the former, the one on the anterior edge of the palp 

 is slightly longer than the last-mentioned one; the two latter bristles are bare or almost so. 

 Exopodite: Of the three bristles of this branch the distal one has short hairs, the two 

 others are plumous. The two distal ones are subequal and of about the same length as this 

 branch, the proximal one being somewhat shorter. Endopodite (fig. 7, cj = ?): The 

 posterior-distal, chitinized, cutting edge of the first joint is rather strongly lobed, the lobes of 

 varying types. Distally this joint has two bristles on its anterior edge and three on the posterior 

 one of about the same proportions as the corresponding bristles in C. (V.) norvegica. The two 

 anterior ones are practically quite bare; of the three posterior ones the long one is powerfully 

 pectinated, the two others are bare or almost bare. The end joint has the same number of bristles 

 as in C. (V.) norvegica: four a-bristles, three b-bristles, three c-bristles and three d-bristles; 

 they are of about the same relative lengths as in the species mentioned, but somewhat weaker; 

 their equipment, especially, is very weak; the a-bristles are bare, the two posterior b-bristles 

 have only a few secondary teeth, the c-bristles similarly have only a few rather weak 

 secondary teeth or are almost bare, and the same is true of the anterior d-bristle. The 

 pilosity is similar to that of C. (V.) norvegica. 



Fifth limb: — P r o t o p o d i t e: The first endite (fig. 8, (J =^ ?) shows a rather 

 great resemblance to this process in C. (Doloria) pectinata. It is furnished with eight powerful 

 masticatory bristles all of about the same type furnished with copious long, powerful secondary 

 bristles, arranged more or less clearly in oblique wreaths. Of these bristles nos. 3, 5, 7 and 8, 

 counting from the anterior side of the limb, are moderately long, decreasing somewhat in length 

 the more posteriorly they are situated; bristles nos. 2, 4 and 6 form a similar series, but are 

 considerably shorter than the former ones: no. 1 is very small. Second endite (fig. 9, (^ = ?): 

 The five inner bristles are powerful masticatory bristles of moderate lengths, the three middle 

 ones being somewhat shorter than the two outer ones. They are all, except the middle one, 

 furnished with some wreaths of long, stiff secondary bristles at the middle. The middle one 

 is sharply serrated distally, the rest are pectinated a short distance distally of the distal wreath
