 -Mandible: - I' r o t o p o d i t e: Coxale: The toothed ediie mi tlir pais ineisiva 

 has from twelve to Hfteen teeth, the anterior one of whicli is of alxait the same relative size and 

 tvpe as in most other species of this genus, the others latlur small, subequal, somewhat irre- 

 jrularly triangular (cf. the acc<unpanying tig. it); some of the posterieir teeth are in some cases 

 a little less developed than in this figure, the most post(>ii()i' one seems, however, almost always 

 to be well developed, sometimes it is even somewhat more jjowerlul than in the above-mentioned 

 figure. Distal tooth-list: This is furnished posteriorly with a rather large and powerlul. fang- 

 like, bare tooth, in front of which there is a single row of about 20—25 subecjual, ratiier small, 

 smooth, triangular serrate teeth; cf. the accompanying fig. 10. Proximal tooth list (fig. 11 ): 

 This varies somewhat in type, but agrees on the whole with the j)receding list. It is armed 

 posteriorly with a rather large and powerful, fang-like, bare tooth, in front of whicli there is 

 a single row of rather small and somewhat irregular pointed serrate teeth. In most cases it has, 

 in addition, unlike what is the case in the distal tooth-list, two or three rather powerful and large 

 fang-like teeth (which are most frequently somewhat smaller than the most posterior large tooth); 

 these have in most cases, at least proxinially. some more or less well-developed secondary teetJi. 

 The inside of this tooth-list is not furnished with close small spines. Both the tooth-lists are 

 of about the same width and are slightly narrower than the distal toothed edge of the pars 

 ineisiva. The masticatory pad is rather high and narrow, about half the width of the tooth- 

 lists, and is divided into about four or five transverse ridges, armed with exceedingly fine, rather 

 short and exceedingly dense spines. The part of the pars ineisiva that is surrounded by the 

 row of bristles and hairs is somewhat pad-like and has finej^apillae, some of which are exceedingly 

 short. Basale: The six teeth on the distal edge of the endite are rather finely serrulated. The 

 single tooth on the outside of this process is in most cases somewhat smaller than in my fig. 19 

 of C. symmetrica, rather finely serrulated or sometimes even almost smooth. The antero-medial 

 bristle on this joint is comparatively long, in most cases almost as long as the proximo-anterior 

 bristle on the endite of this joint, which is about as long as in my fig. 22 of C. symmetrica. 

 There is no epipodial appendage. Endopodite: The first joint has only two posterior 

 bristles, both of which have short hairs; one is situated somewhat laterally and is about as long 

 as or somewhat longer than the total length of the anterior side of the two proximal endopodite 

 joints, the other is situated somewhat medially and is only about a half or a third of the length 

 of the former one. Of the three anterior bristles on the second joint the two longer ones are 

 in most cases somewhat longer comparatively than in my fig. 22 of C. symmetrica; one of them 

 is about as long as the longest of the bristles on the end joint; the other is rather slightly shorter. 

 Pilosity: The second endopodite joint has hairs on its anterior side. 



Maxilla: — Protopodite: Only the antero-inner tube-bristle on the endite 

 of the procoxale has long secondary bristles. Endite on the coxale: On th(> posterior process
