AND PERIPATUS. 
Myriopoda and Arachnida. 
Habitat. — Millipedes are practically confined to damp localities. 
They may be found under logs of wood, stones, or decaying leaves, 
and frequently climbing bushes and trees, especially after heavy 
rains. 
Scorpions, Spiders, and Centipedes are mostly nocturnal, and may 
be met with in both moist and dry situations, under stones, loose 
bark, felled tree-trunks, in burrows — in fact, in any suitable spot 
that affords shelter from the heat and light of day. Some spiders 
are diurnal and may be caught while darting about in the hot sun. 
Many Scorpions and large Spiders live in deep burrows, from which 
they have to be dug out. 
The Trapdoor Spiders close the mouth of the burrow with a movable 
lid, and are hard to detect. They frequently, however, betray their 
presence to the collector by rapidly closing the lid at the sound of a 
footfall. Both Spider and its trapdoor nest should be procured if 
possible. Some species of this group in South Africa, Madagascar, 
South America, and other parts of the tropics make their homes, 
not in the ground, but upon the trunks of trees. They should be 
carefully looked for. Many of the smaller species of Solpugas live 
in Termites' nests and feed upon the occupants. 
Small Spiders may be obtained in abundance by beating or shaking 
bushes and flowers over a sheet of paper or of white linen. 
Most of the web-spinning species live on trees or bushes, and, if
