one The inner of the two intermediate apical bristles is con- 

 side'rably longer than the outer and usually rather longer than the 

 abdomen. The lateral bristles (or cilia) on the proximal parts ot 

 these bristles are short and thin. The anterior antennas when laid 

 back do not reach the hinder margin of the first thoragc segment. 

 la old and large specimens they contain twelve joints, and in smaller 

 a nd younger but clearlv mature specimens ten or e even joints ihe 

 feet of the first four pairs have two-jointed branches. In the first 

 p.ir the second joint of the outer branch has on the outer margin 

 hree spines and on the inner three bristh.-s, and at tte t,p two 

 terminal bristles. In the second and third pairs this joint hasthree 

 spines and four bristles and a terminal bristle and spine and m the 

 fourth pair two spines and four bristles and a termina bristle and 

 spine The fifth foot consists only of a very small rod-sha^jod 

 ioint, which has at the tip a small bristle 



" "Themaleisdecidedlv smaller than the female. Its length without 

 the apical bristles is from -52 to -74 millim. It is somewhat slan- 

 derer than the female and has, like it, a comparatively long firs 

 thoracic segment, which is slightly longer than the abdomen without 

 the apical bristles. The stylets are somewhat shorter than in the 

 female and are about the same length as the two last very short 

 abdominal segments taken together. The anterior antennas have 

 fourteen or fifteen joints, and have on the basal join two pa.rs o 

 long, narrow, cylindrical, blunt, and papillated so-called ' sensory 



''^''" Both sexes are more or less reddish in colour, though subject to 

 variation, being darker or lighter or inclined to greyish red The 

 cephalothorax is usually lighter than the abdomen. The egg- 

 clusters are narrow and generally contain six to eight eggs _ 



''This species is found sporadically throughout Sweden, but is not 

 common. It occurs for the most P^^J «nly in small bogs, but is 

 sometimes also found near the shores of large pools. It is a bottom 

 form It resembles C. varicans in its movements. 



The above description applies exactly to our British specimens, 

 c^vP that in the latter (1) the first thoracic segment is not longer 

 han the abdomefwithoiii the apical bristles," but slightly shorter; 

 and (2) the side bristle on the stylet is situated about two thirds 

 iustead of three quarters of the way down. Our ma ure female 

 specimens were about "70 or -75 millim. in size and their antennas 

 contained eleven joints. We found no males.
