third of the joint: seven long bristles with short, fine hairs, their relative lengths varying and 

 somewhat different from each other, the longest being almost as long as to the end joint; in addition 

 to these seven bristles there are only two more short cleaning bristles, of which the proximal 

 one is almost bare, the distal one with a strong double pectination. On the posterior edge, 

 distally of the middle of the joint, this joint has, as is nsiial in forms belonging to this sub-family, 

 two rather short, bare, spine-like bristles of about the same length, one situated somewhat distally 

 of the other, and near the postero-distal corner there are two additional bristles of the same 

 kind, situated by the side of each other; the medial one of these two bristles is not perceptibly 

 longer and more powerful than the lateral one. The bristles of the end joint (fig. 12) are rather 

 short. The two middle claws are about a quarter of the length of the second endopodite joint, 

 are very powerful and uniformly but rather weakly curved, and have rather few but comparatively 

 jiowerful secondary teeth posteriorly on the proximal half. The two anterior bristles, which are 

 of about the same length as each other, are somewhat shorter than the middle claws ; the medial 

 one of them is developed into a powerful claw of the same type as the latter, the other is rather weak 

 and bare. Of the three posterior bristles, all bare, two are rather weak and about as long as the 

 middle claws or somewhat longer, the other, which is situated most posteriorly, is, as usual, very short, 

 Pilosity: The second endopodite joint has short hairs along the distal part of the posterior side. 

 Maxilla: — Protopodite: The first endite (fig. 13) is furnished with nine 

 powerful bristles of moderate length, eight of which are subequal and one, one of the outer 

 ones, is somewhat shorter. The three innermost of these bristles have simple points and are 

 furnished with a few oblique wreaths of long, stiff secondary bristles; the distal one of these 

 wreaths continues right to the point of the bristles. Of the rest three, including the short one, 

 are trifurcated distally and three have a powerful simple point; all of them are furnished at the 

 middle with rather few long, stiff secondary bristles and distally with fairly powerful secondary 

 teeth; the secondary teeth are most powerfid on the bristles with simple points. The second 

 endite (fig. 14) has seven bristles of moderate length. Of these the inner one is rather power- 

 ful, trifurcated distally and is furnished at the middle with a moderate number of long, stifi 

 secondary bristles, distally of which there are a few rather strong spines. The three bristles 

 fixed close to this bristle are subequal and somewhat shorter and considerably weaker than it; 

 they are weakly pectinated distally and one of them has a few long secondary bristles at the 

 middle. The three outer bristles are rather powerful, especially the innermost one of them, 

 subequal and somewhat longer than the other bristles on this process; the innermost one has 

 a few long, stiff secondary bristles at the middle, the rest have no such bristles; all of them 

 are rather strongly pectinated distally. The third endite (fig. 15) has five rather powerful distal 

 bristles, of which the outer one is rather long, the four others being subequal and of moderate 

 length. The outer one has a large number of long, stiff secondary bristles situated close together 

 and is finely pectinated distally. Of the rest the next to the outer one and the inner one have 

 short, fine hairs, almost bare, and the two remaining ones, which are somewhat more powerful 

 than the two former, are rather strongly pectinated distally. The proximal bristle on the outside of 

 this process has short, fine hairs, almost bare, and is about half the Icngtli of the outside of this 

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