telephone wires, e»g. on the way to Tanjong Katong. The most 
common spider in houses and stables is Epeira insidana. It is 
mottled grey above and is marked below with bright red and 
yellow spots. Its legs are alternately banded black and white. 
It constructs large and elaborate webs, and is widely distributed 
from S. Europe and N. Africa through S. Asia to Australia.— 
The most extraordinarily shaped Malayan Spiders are the 
various species of G aster acantha, G. dhdesmia has a body 
broader than long, somewhat after the shape of a crab, drawn 
out into two spines at either side. It is yellow above, with two 
brown bands. Yet more curious is G, arcimUi in which the 
body at either side is prolonged into a very long and slender 
horn. It is yellow above, with numerous brown tubercles. 
Both species spin webs.— The Hunting Spider {Heteropiida 
venaUma) does not construct snares, but hunts its prey. It is a 
large and long-legged, hair>' species, running side-ways, in a 
crab-like fashion, but with great speed, and is often seen in 
houses after dark. The female carries her eggs in a fiat cocoon 
below her body.— Common in houses and gardens are the AttMae 
or Jumping Spiders. They are of small size, have short legs 
and construct no snares either. They are frequently seen on 
mosquito curtains going after moths. 
7. The Opilioties or Harvest Spiders resemble the true 
Spiders in outer appearance, but differ from them by having 
tubular tracheae instead of * lungs,' and by the absence of 
spinnmg mamillae. Their body is small, but the legs are 
exceedingly long and slender. 
8. The Pscudoscorpiones or False Scorpions are all small, 
even the largest species barely reaching M inch in length. They 
resemble the true Scorpions in their general shape, especially 
through their comparatively large pincers, but differ from them 
by having no tail and no poison sting and by breathing through 
tracheae instead of through lungs. They are found under the 
bark of trees, under moss and stones, also in books, in insect 
cabinets and such like places. From their habitat they have 
also been called ' Book-Scorpions.* They do no damage, but 
on the contrary they are useful by destroying mites. The best 
known genus is Chelifer. 
g. The Acari or Mites and Ticks are of minute size. 
They show a great diversity in structure, many of them having 
become degecierated through their parasitic mode of life. Their 
respiratory organs, when present, are tracheae : however, they 
may be absent altogether. None are exhibited.
