pectinated, the two anterior ones have only a few secondary teeth. The posterior edge of this 

 joint is irregularly undulated distally, forming a low cutting process. The end joint (fig. 10): 

 This is moderately chitinized. Usually it has six (in a single case seven) a-bristles of moderate 

 strength and length, naked or with sparse, weak secondary teeth; this joint has, in addition, 

 lour b-bristles, four or five, in most cases five, c-bristles and three d-bristles. The b-bristles 

 are most frequently subequal, of moderate length and strength, the anterior one of them 

 sparsely but strongly pectinated, the rest usually only with a few secondary teeth in the middle. 

 The c-bristles are often placed somewhat irregularly, some of them about as long and strong as the 

 b-bristles, the others rather short and weak; the longer ones among them have rather powerful 

 but sparse secondary teeth, on the shorter ones the secondary teeth are fewer and weaker and 

 may even be quite absent. The d-bristles are somewhat longer than the b-bristles and very 

 powerful, especiallv the two anterior ones; they are armed with sparse, coarse secondary teeth, 

 the anterior ones most frequently with only a few of these. Pilosity: The epipodial plate of 

 the protopodite is partly furnished with fine hairs. Tlie first endopodite joint has anteriorly- 

 distally groups of fine short hairs. 



Fifth limb: — Protopodite: The first endite (fig. 15) has in most cases 

 fourteen bristles; in one case among the specimens fromS/S ,,M i c h a e 1 S a r s" only thirteen 

 were observed, while the specimens from S/S ,,A n t a r c t i c" had fourteen or fifteen bristles 

 on this [jrocaasi. OF these bristles the inner-anterior one is rather short, almost bare or furnished 

 with one wreath or a few wj-eaths of long secondary bristles. The rest are moderately or rather 

 long, their relative length somev^-iiat varying, in most cases being about what is shown in the 

 adjoining figure; they are all rather povt-f^j-ful and have a varying, in most cases rather large 

 number of wreaths of long, stiff secondary bristles; -most of them are fitted distally with a 

 varying number of rather powerful secondary teeth, .some are bare distally. The five inner 

 bristles of the second endite (fig. 16) are rather powerful, subequaJ, of moderate length, all with 

 a number of wreaths of long, stiff secondary bristles, the middle one c>f them finely serrated, the 

 rest with rather coarse secondary teeth distally, generally somewhat fewer and coarser on the 

 two posterior bristles than on the two anterior ones. The bristle a \itt\e farther out on the 

 anterior side of this process is short, bare or almost bare. Third endite: (fig. 17) AH seven 

 bristles are of moderate length, subequal except nos. 5 and 6, reckoning frorn the front, which 

 are somewhat shorter than the rest; the five anterior ones are rather powerful, the two posterior, 

 especially the most posterior, very powerful. The two anterior ones are of tire same type as 

 each other, fitted with several wreaths of long, stiff secondary bristles in the middle and rather 

 coarsely pectinated distally; the three middle ones are generally without long secondary bristles, 

 two of them are finely serrated, tlie third coarsely pectinated distally; the two posterior ones 

 have several wreaths or cross-rows of long, stiff secondary bristles in the middle, dlistally they 

 are somewhat V)ent and armed with a somewhat varying number of secondary teeth, of which 

 the proximal ones are very powerful. T h e e p i p o d i a 1 p 1 a t e has about seventy to 

 eighty marginal bristles; on the ventral ones of these the distal third or (juarter is naked or has 

 .short hairs, on those situated more dorsally tlic long hairs extend still farther out towards the 

 point (^f the bristles; on all of them, however, the point itself is quite naked. The, structure
