pi. XVII, fig. 27; el', tlie areompanving figs. 7 ami 8; both these organs are furnished proxinially 

 with one or two verruciform processes and have exceedingly weak transverse creases distally. 

 The h-, i- and j -bristles are subequal, about as long as or somewhat shorter than half the length 

 of the g-bristle; they have a proximal part that suddenly becomes very narrow, about the same 

 as in the accompanying fig. 7; they are very thin and hyaline, irregularly rolled u]) and bare. 

 M a i\ d i b 1 e: -- P r o t o p o d i t e: Coxale: The toothed edge on the pars incisiva 

 has from twelve to fifteen teeth, the anterior one of which is of about the same relative size and 

 type as in most other species of this genus, tlie others rather small, subequal, somewhat irre- 

 gidarly triangular (cf. the accompanying fig. 9); some of the posterior teeth are in some cases 

 a little less developed than in this figure, the most posterior one seems, however, almost always 

 to be well developed, sometimes it is even somewhat moi'e powerful than in the above-mentioned 

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

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

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

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

 posteriorly with a rather large and powerful, fang-like, bare tooth, in front of which 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 frec[uently somewhat smaller than the most posterior large tooth); 

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

 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 

 incisiva. 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 incisiva that is surrounded by the 

 row of bristles and hairs is somewhat pad-like and has fine pajiillae, some of which are exceedingly 

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

 single tooth on the outside of this j^rocess 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 e p i p o d i a 1 a p p e n d a g e. En d o p o d i t e : 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 endo]iodite 

 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 ('. 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 t\;be-bristle on the endite 

 ol the ])i-oco\ale has long scH'ondarv bristles. Endite on the coxale: On the ]iosterior ]irocess
