also been collected near Port Elisabeth, Cape Colony, a sea- 
port town; Peripatoides oviparus (Dendy) is not only re- 
corded from Mt. Kosciusko but also from Pyalong and War- 
burton in Victoria, localities for which the International 
Map of the World shows altitudes of 200-300 meters; Oro- 
peripatus corradoi (Camerano) comes from the Quito plain 
in Ecuador which is at 9,500 feet altitude but it is also re- 
ported from near Guayaquil on the coast. The ability of 
Peripatus to withstand the great range of conditions to 
which it must be subjected at these various altitudes would 
seem to be worthy of consideration in relation to the prob- 
lem of dispersal of this animal. Also, the fact that indi- 
viduals showing the same specific characters are found in- 
habiting such diverse regions may be regarded as further 
evidence of the very slight tendency towards speciation in 
this group, which has resulted in its retention of so many 
primitive characteristics.
