INTRODUCTORY NOTE 
O NLY three examples of this group were preserved by us, and we did 
not see many more.* Indeed, as I have noticed on both my visits to the 
Patani States, Land Planarians are very scarce in this district in dry 
weather, and by no means common even during the stormy season, whereas 
in the interior of Kelantan they are comparatively abundant in a moderately 
moist environment, such as exists in August and September at Kuala Aring. 
There is no reason to think that the species are less numerous in the southern 
half of the Malay Peninsula than they are in Java or Ceylon, but they have 
been very little collected.
