After a little experience I got to know tlie likely-looking parts, 

 and even the most promising logs under which to search. All 

 the specimens were underneath logs, either on the ground or on 

 the undersurface of the Jog, and in the cracks and crannies in the 

 soil beneath the logs. Small easily rolled logs yield the best results 

 for Peripatus as well as for land Planarians and the other creatures 

 that live under them; large heavy ones lie too hard and close to 

 the ground, and do not give the necessai-y room underneath. 



The colours of the individuals were exceedingl}'- variable. 

 Adopting a similar method of comparison to that used by Mr. 

 Fletcher* in his description of the collection made by Mr. Helms 

 at Mt. Kosciusko, my specimens very naturally divide themselves 

 into four groups : — a. Black or blue-black, b. Black, sparingly 

 speckled with rufous brown. c. Rufous bi-own with black 

 antenn;^ and with or without visible scattered black spots or 

 specklings. d. Entirely rufous brown or red, including the 

 antennte, and without an}^ visible black. 



The relative numbers of individuals in each of these classes 

 was : — 



a. Black or blue-black ... ... 77| per cent. 



h. Black, speckled with brown ... 6^ ,, ,, 



c. Brown, black antennae ... ... 10 ,, ,, 



d. Entirely brown ... ... ... 6 „ ,, 



In the Mt. Kosciusko collection the proportion of entirely 

 black individuals is very much smaller than the above, amounting 

 to only about 9 per cent, of the whole, the greater number being 

 dark, sparingly speckled with brown. 



No specimens with antennae and body both entirely brown are 

 mentioned, and indeed, judging from the published descriptions 

 and my own experience, this particiilar form aj^pears to be much 

 less common than the others. Such being the case, it may be 

 well for me here to briefly describe those in my collection. To 

 the naked eye or the microscope there is no trace of black visible.
