638 TAGE SKOGSBERG 



joint: The c- and d-bristles are rather shghtly shorter than this joint; they have short hairs 

 or are almost bare. The e-bristle is short. The g-bristle is somewhat shorter than the proto- 

 podite, the f-bristle is about a quarter or a fifth shorter than the g-bristle; both these bristles 

 are narrow distally and have sparse, short hairs. Third joint: The clasping organs are of the 

 types reproduced by G. W. MCller, cross-striated distally (in the specimen investigated by 

 me, however, they had no distal papilla as in the figures given by this writer). The h-, i- and 

 j -bristles are subequal, somewhat less than half the length of the g-bristle and somewhat narrower 

 than the f-bristle; they all have faint indications of shafts and are almost quite bare. 



Mandible: — Protopodite: Coxale: The toothed edge on the pars incisiva 

 has about ten to twelve teeth, the posterior ones are, however, so small that their number is 

 difficult to decide. Distal tooth-list (fig. 6): This is of about the same relative sizi; and type 

 as has been described above for C. ohlonga ; sometimes, however, it has only one large posterior 

 tooth; the number of teeth varies from fourteen to twenty. Proximal tooth-list: This is about 

 as wide as the distal one. It has three or four powerful, conical, smooth posterior teeth and in 

 front of these a dense row of rather fine serrate teeth; see the accompanying fig. 6. In other 

 respects this joint is of about the same type as has been described below for C. symmetrica. 

 Basale: The six teeth on the distal edge of the endite are finely serrulated. The sing'- tootli 

 on the outside of this endite is of about the same relative size and type as in C. elegans. The 

 e p i p o d i a 1 appendage consists of a small verruca and a very short bristle. E n d o- 

 p o d i t e: The first joint has four posterior bristles, which have about the same positions and 

 lengths as in C. symmetrica and have short hairs. 



Maxilla: — The bristle on the basale, Like most bristles on the anterior and posterior 

 edges of the first endopodite joint, has a larger or smaller number of rather long secondary bristles. 

 The end joint is relatively short; see the accompanying fig. 7. 



Fifth limb: — This is of about the same type as in C. symmetrica, but the longer 

 of the two tube-bristles on the second endite of the protopodite has short hairs and the 

 endopodite has no spines. The two shorter of the three antero-ventral bristles on the 

 endopodite are sometimes furnished with short hairs or sometimes one or both of them have 

 rather long secondary bristles. First exopodite joint: From one to three of the four 

 or five proximo-ventral bristles are sometimes furnished with rather long secondary bristles; 

 sometimes they all have short hairs. One of the three or four ventero-distal bristles is 

 sometimes furnished with rather long secondary bristles, sometimes they all have short hairs. 

 The protopodite and the first exopodite joint are partly furnished with rather long hairs. 



Sixth limb: — The bristles of the endopodite have short hairs. Exopo- 

 dite: First joint: One of the anterior ones of the five ventral bristles is of about the same type 

 and relative length as the corresponding bristle in my fig. 29 of C. symmetrica, the others are 

 relatively short and have short hairs. 



Penis: — This is of about the same type as is reproduced by Gr. W. MtlLLER ; see the accomp- 

 anying fig. 8. It has four oblique transverse muscles at the middle. Distally of these there is 

 a collection of powerful muscles which have one end attached to the l)ase of the copulatory 

 appendage, from which point they radiate out like a fan towards the antero-dorsal side of the organ.
