568 AUSTRALIAN LAND PLANARIANS, 



colour, but all diffuse and with ill-defined margins. They are 

 spaced at about equal distances apart. The median line is if 

 anything, usually slighter and less strongly marked than the 

 others. In G. quinquelineata, var. accentuata, mihi (ll, p. 110, 

 pi. vii., fig. 7) the equal spacing of the lines is preserved, the 

 variety differing from the species merely in having the median 

 line accentuated. 



As showing the variation in the character of the lines, PL 

 xxxiv., fig. 8, illustrates a specimen of G. quinquelineata from 

 Milton, N.S.W., collected and given to me by Mr. W. W. 

 Froggatt, F.L.S. This example has all the lines broad and 

 diffuse, almost confluent, and with very narrow spaces of body 

 colour betwefm.

 Australia (two spirit specimens; Mr. C. G. Hamilton).

Part ii. — Notes on habits, collection and preservation. 



(a). Habits. — Since the publication of my former paper on 

 Land Planarians, I have received from friends desirous of aiding 

 in the study of these creatures, numerous enquiries as to their 

 mode of occurrence, habits, &c, and for the purpose of dissem- 

 inating information on these points, I have thought it well to 

 include in this paper the following notes : — 



Land planarians are to be met with in Australia chiefly under 

 logs and pieces of wood lying about in paddocks adjacent to 

 scrub. In the scrub itself they are not so readily found because 

 of the larger amount of available shelter, and because the insects 

 on which they prey are more abundant under the logs in the open. 

 Like other creatures of similar habits they are found most plenti- 

 fully where the soil is rich, this fact doubtless being due to the 

 more fertile land supporting a larger insect population, and, 

 therefore, providing a better supply of food than is present in
