It appears, from these observations, that the distribution of 
spiders presents no greater difficulties than the large groups 
of insects. The anomalous cases may be explained by sup¬ 
posing that the isolated species are the remains of genera which 
had, formerly, a wider distribution, the intermediate species 
having become extinct. It is probable that many difficulties 
will disappear when spiders have been thoroughly collected. 
We shall then have better opportunities for classification and 
many gaps will be filled. All deductions from the material 
at present available are tentative. Although ten thousand spe¬ 
cies have been described, there are doubtless twice as many 
that have not yet been discovered.
