species of Theridion, which makes an irregular snare, is more careful in the planning of her nursery. 
Adjoining the snare, she constructs a conical tent open at the bottom only. Then she fabricates 
globular cocoons of yellowish-white, in each of which she encloses from twenty to sixty small eggs 
of similar colour to the silk, and hangs these up in the roof of her tent. When the eggs hatch the 
young spiders remain in the tent for some time, and the mother-spider brings them food. Another 
member of the same genus, distinguished by having her upper side marked by delicate black lines on 
a pale greenish ground, makes a greenish or bluish egg-bag, and secures it to a leaf, and by means 
of properly placed threads, draws the 
edges of the leaf towards the middle, 
and so hides her treasure. A some-

(Mammillifera) is a social one, and by continuous budding forms a sheet of connected 
anemones large enough to cover the crab. This particular Hermit does not utilize an empty 
shell for the protection of its soft hinder parts, mainly, we suspect, because at the depth it 
affects mollusc-shells are not a plentiful commodity. So this cloak-like colony of anemones 
serves instead, and when danger threatens the crab seizes the front edge of its coverlet and draws 
it over its head. 
Alcock tells us that in the deep waters of these Indian seas the Hermit Crabs differ from most 
other deep-sea animals in having normally developed eyes, and that the anemones they carry about 
with them are frequently luminous, so that the light they give out enables the crab to see what he
