bnre at tho lattor part. The innor lobo of the third joint is rathor small (fig. 23) and has two 

 or throo rathor powiTiul ilistal bristlos of inodorato and somewhat dilTcront lengths, the lengths 

 varying to some extent; these bristles liave either short hairs or else rather coarse secondary 

 spines. In addition tiiis Idho has proximally ^>u the posterior side a fairly long bristle, with 

 short hairs distally and usually with long hairs at the middle. Tlic outer lolx- of tliis joint lias 

 two moderately long distal bristles, usually subequal, with long hairs at the middle and short 

 hairs distally, but sometimes, however, the inner one, sometimes the outer one has only short 

 hairs. The end joint, which is fairly large and without any signs of any further division into 

 joints, has five or six, usually six, moderately long and rather powerful distal bristles; their 

 relative lengths vary to some extent. Pilosity: The two last-mentioned joints are rather 

 sparsely furnished with soft hairs. 



Sixth limb (fig. 25) : — This is rather elongated and has a rather varying number 

 of bristles; the types and relative lengths of the bristles also vary both from one specimen to 

 another and on the right and the left side of the same specinien. Protopodite: The first 

 endite has only one rather long and powerful distal bristle, furnished with about three oblique 

 wreaths of secondary bristles and pectinated distally; this endite always seems to be without 

 any medial bristles. The second endite usually has three distal bristles, of which the two dorsal 

 ones are subequal, rather long and powerful and have at the middle a few wreaths of long, stiff 

 secondary bristles and are pectinated distally; the ventral bristle is somewhat shorter, but 

 powerful, at the middle it has a wreath of long, stiff secondary bristles, distally of which there 

 are a few powerful secondary teeth. This process usually has, in addition, two short, plumous 

 medial bristles. Variations in the number of the bristles were observed, the following numbers 

 were found: three distal bristles + one medial bristle; three d. + three m., four d. + two m., 

 four d. + three m, and even four d, + four m. The third endite usually has three distal bristles 

 and one medial bristle. Of the former the middle one is of the same type as the ventral one 

 on the preceding endite, the dorsal and the ventral ones vary in type, sometimes having short 

 hairs, sometimes having one or a few wreaths of long, stiff secondary bristles at the middle and 

 short hairs distally. The medial bristle is of about the same length as the distal bristles and has 

 a wreath of long secondary bristles at the middle and short hairs distally. Variations were 

 observed with regard to the number of bristles, the following numbers were found: three distal 

 bristles -f no medial bristle, three d. + two m. and four d. + one m. The e p i p o d i a 1 

 appendage of the protopodite is represented by from two to four short, bare or almost 

 bare bristles. Exopodite: First joint: The endite usually has six distal bristles and one 

 medial bristle. Of the former one of the middle ones is about the same as the ventral distal 

 bristle on the second endite of the protopodite, the others are rather long and powerful, varying 

 in type, sometimes having short hairs and sometimes with one or a few wreaths of long, stiff 

 secondary bristles at the middle and short hairs distally. The medial bristle is similar to the 

 corresponding bristle on the preceding endite, sometimes, however, having only short hairs. 

 Other numbers of bristles that were observed were as follows: six distal + two medial bristles, five 

 d. + one m. and three d. -f one m. Second joint: This has from 25 to 32 bristles, some rather 

 long and others rather short, all situated near the ventral edge; there is no pronounced gap
