700 TAGE SKOGSBERG 



a quarter or a sixth shorter and is bare. Third joint: The ckisping organs are of about the types 

 reproduced by G. W. MULLER, 1906 a, pL XXII, figs. 27 and 28. The h-, i- and j-bristles are 

 subequal, about as long as or somewhat shorter or longer 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, 

 only slightly widened proxi mally , with rather distinct shafts and with short, fine hairs or almost bare. 

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

 has about ten teeth. The distal tooth-list is of about the same relative size and type as has been 

 described above for C. ohlonga. Proximal tooth-list: This is rather slightly narrower than the 

 distal one and varies somewhat in type; its teeth, which vary in number between about ten and 

 eighteen, are sometimes developed in about the same way as is shown in fig. 6, i. e. they are 

 all conical, more or less pointed, smooth, the posterior ones rather large and powerful, the others 

 decreasing rather evenly in size and strength the more anteriorly they are situated, or else they 

 are more unequal in strength and shape, the anterior ones being smaller and more numerous. 

 On the inside this tooth-list is furnished with numerous short, fine spines situated close together. 

 The masticatory pad is of aboiit the type that is reproduced by C. Claus, 1891 a, pi. I, fig. 9, 

 i. e. it is relativelv narrow, being only about half the width of the tooth-lists, and is divided into 

 about four to six transverse ridges, which are armed with rather small, low, irregular papillae. 

 In addition there are, close to the side of the masticatory pad that points towards the lancet- 

 bristles, a couple of low verruciform spines like those in the figure just mentioned. Basale: 

 The six teeth on the distal edge of the endite are furnished with rather fine serrulation. The 

 single tooth on the outside of this endite is of about the same tv'pe and size as in my fig. 19 of 

 C. symmetrica; its serrulation is very difficult to discover; the shape varies, however, to some 

 extent. The e p i p o dial a p p e n d a g e consists of an extremely small verruca with or 

 without a veiy short and fine bristle. (This appendage is sometimes so small that it is scarcely 

 perceptible with Reichert's ocular 4, Leitz's immersion Vi,.) Endopodite: The first 

 joint has only two posterior bristles, both of which have short hairs, one situated somewhat 

 laterally and rather long, about as long as the anterior side of the endopodite, the other, situated 

 somewhat medially, is only about a third or a half the length of the former one. Pilosity: The 

 rows of hairs on the posterior side of the basale are represented by only a few hairs. 



Maxilla: — Protopodite: Endite on the coxale: On the posterior process 

 there are only three, not four tube-bristles, as is usual in this genus. Endopodite: The 

 ventral side of the end joint is about as long as the distal width of the first endopodite joint 

 (calculating from front to back), its dorsal side is about half as long. 



Fifth limb: — Protopodite: The longer of the two tube-bristles on the 

 second endite has short hairs. E n d o p o d i t e: Of the three ventral-anterior bristles one is 

 usually of the same length and type as the long bristle on the first endite and has in most cases 

 long secondary bristles, one is about as long as or slightly shorter than the former, but has short 

 hairs, the third is relatively short and weak, often about half or a third the length of the longest 

 claw on tliis branch, and has short hairs. The dorsal tube-bristle is relatively short, often only 

 about half as long as the short claw; the other tube-bristle is also rather short. This branch 

 has no spines. E x o p o d i t e: First joint: This has one or two medio-veiitral bristles, in most
