separated. In Trichoniscus vividus the antennz 
lack the bristles which characterise those of the 
other species in the genus. The species under 
consideration was discovered by Dr. Kinahan 
in March, 1858, at Portlaw, Co. Waterford and 
is active even amongst the snow.

The third British species of Tvichoniscus is of a deep pink 
colour and has a light yellow stripe down the back (in some 
habitats the animals are said to be quite white). 
Arranged in transverse rows upon the body are 
large tubercles, each of which under strong 
magnification will be found to end in a tiny 
hair. It is distinguished from Tvichoniscus 
pusillus by the larger size of its body, which is 
also comparatively broader, and from Tvichoniscus 
vividus by the four joints of the flagellum of its 
antenne which latter have strong bristles upon 
them. In the former species there are five or 
more joints to the flagellum and the antenne, 
though hairy, lack the bristles. Tvichontscus 
voseus is to be looked for in old gardens.
