sparse short, fine liairs; others, especially those situated more distally, have only shori \ 

 fine hairs or are ahnost bare. In addition there are numerous short cleaning bristles, al ( 

 of about the same length, of two types, 22 — 25 of them with an extremely fine and denst 

 double pectination (fig. 8; drawn as smooth in fig. 6), and a smaller number, about six or seven, 

 with very powerful double distal pectination (fig. 9; the spines are shown in fig. 6). On the 

 posterior edge this joint has, in addition, somewhat distally of the middle, two bristles, both 

 of the same tvpe, rather short, bare and spine-like, one of them situated somewhat distally of 

 the other. Near the posterior distal boundary of the joint there are also two smooth, straight, 

 spine-like bristles (fig. 10), situated at the side of each other; the lateral one of these is about as 

 strong as the two last-mentioned bristles, but somewhat shorter than these, the medial one is 

 considerably stronger and is about twice as long as the lateral one. The small end joint (fig. 10) is, 

 especially posteriorly, very strongly chitinized. Of its bristles the two middle ones, the main 

 claws, are extremely powerful, but short, being only about a fifth of the lengtli of the second 

 endopodite joint, and very strongly serrated along the proximal two-thirds of their length; (for 

 practical reasons this serration is only drawn on one of these claws in the adjoining figure); 

 of these two claws the lateral one is rather considerably shorter than the medial one. The 

 two anterior ones, somewhat different in length from each other, are rather considerably shorter 

 than the middle claws, weak and quite bare. Of the three posterior bristles, all bare, two are 

 somewhat weaker than the two anterior ones, one of them being about as long as the longest, 

 the other as long as the shortest, of the main claws; the tliird one of these bristles is very short. 

 Pilosity: The first endopodite joint has short hairs dorso-distally, the second endopodite joint 

 has posteriorly groups of short, fine hairs placed transversally. 



Maxilla (fig. 15): — Protopodite (fig. 16) : First endite: The bristles on the 

 only .specimen of this species I have had the opportunity of examining were defective; ten strong, 

 subequal bristles of moderate length were observed. All of them were furnished with rather 

 numerous long, stiff secondary bristles; on the two (originally there were presumably three) inner 

 ones the secondary bristles continued right to the point of the bristles, on the others they 

 stopped a short distance from it. Of the latter three were trifurcated distally and five had 

 a simple strong point. Of the latter five one was smooth distally, the others were furnished with 

 powerful distal secondary teeth. The second endite has seven rather powerful, subequal, moder- 

 ately long bristles. All of them, except the one next to tlie outermost one, seem to be furnished 

 at the middle with long, stiff secondary bristles; the four outer ones are pectinated distally, 

 the three inner ones are smooth distally. The third endite has five moderately powerful distal 

 bristles, of which the outer one is unusually long, about twice as long as the ne.xt outer one; 

 the rest are moderately long, the inner one being somewhat shorter than the others. The inner 

 bristle has short hairs; the outer one has, along a large part of its length, rather mimerous, long 

 and comparatively flexible secondary bristles and is extremely finely pectinated distally. The 

 three remaining ones of these bristles have a moderate number of long, stiff secondary bristles 

 at the middle, and are pectinated distally, the pectination on the inner one of them is. however, 

 very weak. The proximal bristle on the outside of this endite is about half the length of the 

 outside of the process and has short luiirs. The dorsal bristle of the coxale is attached at about
