fies. 1—14. 
Body robust ; abdomen of the female 4-, of the male 
5-jomted. Anterior antenna (fig. 1) as long as the 
first segment of the body, 9-jointed, almost exactly 
similar to that of C. trispinosus. Secondary branch of 
the posterior antenna very small, 1-jointed. Mandible 
(fig. 4) very slender, palp minute. Second foot-jaw and 
first pair of feet (figs. 7 and 8) as in C. trispinosus. 
Inner branches of second, third, and fourth pairs of 
feet 2-jointed (fig. 9), the first joint very small. In 
the male the inner branch. of the third foot (fig. 11) is 
3-jointed, and the middle joint 1s produced downwards 
into a long crooked spine; the last joint has three 
apical setz. Basal joint of the fifth foot in the female 
broad, the inner segment not at all produced, but 
fringed with six stout plumose sete; second joint 
broad, quadrangular (fig. 12), and armed with five 
stout plumose setze, one of which is much longer than 
the rest; in the male the inner segment of the basal 
joint (fig. 13) has only three setz; the second joint 
small, subtriangular, and having a setose armature 
somewhat similar to that of the female. The hinder 
margins of the abdominal segments (fig. 14) are ser- 
rated with two rows of small teeth, and the anal oper- 
culum is also sparingly denticulated (fig. 14a). Length 
sth of an inch (‘9 mm.). 
‘This species I have found only sparingly in the lake 
at Bolam, Northumberland.
