proportion hctwocii tho Icnjltli of the lonjicst iiatatorv hristlcs and that of tlic i-xopoditc is about 

 4 : 3. Thi* first joint is furnisluHl proxinio-iiistaliv with a dense h)iiiiitudinal row of sliort, fine 

 spines alonij about a (piarter or a third of its length and rluse to lliis mw there is a hirj^er or 

 smaller nunil»er of seattered spines of the same tvpe (about the same as in liys. 12 and l."} of 

 ('. si/mmelrica). !•] n d o ji o d i t e: First joint : The processus mam miliar is has no distal verruca. 

 The a- and b-bristles have no Ioul; haiis. m most cases the\' aic iiuite haie. Second joint: The 

 c- and d-bristlos are most often somewhat shorter than this joint and liave short line hairs t)r 

 are almost i|uite bare. The e-bristle is e.\ceedinf>;lv short. The ^-bristle is about as lonjf as or 

 slightly shorter than tiie ])rotopodite; it grows jrraduallv narrow distally and is furnished with 

 rather sparse short tine hairs. The (bristle is alioul a (juarterora third shorter than the g-bristie 

 and. lil<e it. is not widened distally and is bare, 'i'hini joint: The clasping organs are of about 

 the same types as are re])niduce(i ii\ (J. \V. .Ml l.l.i;i;. MKMia. pi. IX, figs. 22 and 23 (se(i the 

 adjoining fig. 6). The h-. i- and j-iiristles are subecjual, in most cases somewhat less than half 

 the length of the g-bristle; along the greater part of their length they are about as wide as the 

 proximal part of the f-bristle; they are only slightly widened proximally and have only indic- 

 ations of shafts; they are bare. 



Mandible: — 1' r o t o p o d i t e: Coxale: The number of teeth on the toothed 

 edge of the pars incisiva varied between seven and ten in the specimens investigated by tne. 

 Distal tooth-list: This is rather slightly narrower than the toothed edge of the pars incisiva and 

 is of about the type reproduced by me in fig. 17 of C. symmetrica, but somewhat variable. It 

 is armed with a simple row of about 14 — 18 teeth. The two posterior ones of these teeth are 

 rather high and ])iiwerful. tht> posterior one of them is iii most cases smooth, the other is most 

 frequently furnished with a few small secondary teeth. The others, 12 — 16, are somewhat 

 lower than the former ones and are smooth; they are either subequal and somewhat rounded 

 distally (about the same as the middle teeth in the figure just mentioned) or else the anterior 

 ones are somewhat larger and wider than the others (about the same as in the figure just men- 

 tioned). Proximal tooth-list: This is rather slightly narrower than the distal one and is armed 

 with a somewhat varying number (about 14 — 20) of teeth, arranged in a simple row. As in 

 the case of the distal tooth-list, the two posterior of these are rather high and powerful, like 

 tusks, the others vary rather as to their development, being sometimes of about the same type 

 as the corresponding teeth on the distal tooth-list, sometimes of other types, as, for instance, those 

 shown in the adjoining fig. 7. This tooth-list is furnished on the inside with numerous fine, 

 short spines, situated close together. The masticatory pad is simple or at any rate without any 

 distinct division into lobes; it is comparatively wide, about as wide as the tooth-lists; it is square 

 distally and is armed with exceedingly numerous rather small spines. The lancet-bristles are, 

 as C. Cl.\US pointed out, 1891 a, p. 63 ,,in dem dichten Borstensaum mehr oder minder ver- 

 steckt". Basale: The six teeth on the distal edge of the endite are furnished with exceedingly 

 fine serrulation. The single tooth on the outside of this process is of about the same size and 

 type as in my fig. 19 of C. symmetrica, finely serrated only along the distal half of the anterior 

 edge. The e p i p o d i a 1 appendage is represented only by an exceedingly small 

 (scarcely observable with Reichert's ocular 4, Leitz's immersion V,,) verruciform process.
