about fifty to sixty bristles, all with long hairs right out to their jjoints. E x o p o d i t e: This 

 has four joints. First joint: The main tooth (fig. 22) consists of six constituent teeth, all well 

 defined proximallv. whose secondary teeth are of abovit the same type as that shown in the 

 accompanying figure. The bristle on the posterior side of this joint, close to the main tooth, 

 is about as long as the anterior constituent tooth of the main tooth, is furnished at the middle 

 with a wreath of long, stiff secondary bristles and is rather strongly pectinated distally or else 

 almost bare. On the anterior side of this joint there are four bristles, three in a row near the 

 main tooth and one farther out. Of these bristles the two situated nearest to the main tooth 

 are rather long and subequal, the one next to the main tooth is powerful and is strongly pectinated 

 distally but has no long secondary bristles, the other one is somewhat weaker and has long 

 hairs at the middle and short ones distally. The two remaining of these bristles are somewhat 

 shorter than the former ones, the inner one being the shortest, and are of about the same type, 

 having long hairs at the middle and short ones distally. The second joint (fig. 23) is furnished 

 with three a-bristles, five b-bristles, one c-bristle and one d-bristle. Of these the a-bristles are 

 very powerful and have very strong secondary teeth, the b-bristles are rather powerful; the c- and 

 d-bristles are of moderate length and of the same type, having long, soft hairs at the middle 

 and short hairs distally. The outer and inner lobes of the third joint, like the end joint, are 

 of moderate size. The inner lobe of the third joint has two distal bristles of moderate length, 

 the outer one has long hairs at the middle and short ones distally, the inner one is bare and 

 somewhat shorter than the outer one; in addition this lobe has a single bristle posteriorly, somewhat 

 more proximally, which is a little shorter than the distal ones and has long hairs at the middle 

 and short ones distally. The outer lobe has two distal bristles of moderate length, the outer 

 one being somewhat shorter than the inner one; both have long hairs at the middle and short 

 ones distally. The fourth joint has three distal bristles of moderate length, one with long hairs 

 at the middle and short ones distally, the two others with short hairs. Pilosity; The outer lobe 

 of the third exopodite joint is partly furnished with fine hairs. 



Sixth limb (fig. 24): — P r o t o p o d i t e: The first endite has one rather long 

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

 two short, plumous medial bristles. Second endite: This has three distal bristles, two of which 

 are rather long and powerful, furnished at the middle with long, stiff secondary bristles and with 

 short hairs distally, the third, the middle one, is rather short and has long hairs at the middle. 

 This endite has, in addition, two medial bristles, one of which is short and plumous, while the 

 other, which is about as long as the long distal bristles, has long hairs at the middle and short 

 ones distally. Third endite: This has three distal bristles corresponding approximately to those 

 on the former endite, the dorsal one being, however, furnished only with short hairs; in addition 

 there is one medial bristle, of the same type and length as the long medial bristle on the second 

 endite. The e p i p o d i a 1 appendage of the protopodite is represented by five unusually 

 long, bare bristles, the distal ones of which are considerably longer than the proximal ones. 

 .Exopodite: First joint: The endite has six distal bristles and one medial bristle, of the 

 same types as the bristles on the preceding endite. The second joint is about twice as broad 

 as it is long, and has nine or ten bristles, all situated near the ventral edge; there is no pronounced
