Specimens of Peripatus from Jarrahwood, in the south, have 
been kindly collected for me by Mr. L. le Souef. These specimens 
I had fully expected to be like those from the Darling Ranges. 
In fact, it would not have been surprising to me if the species 
named P. occidentalis by Fletcher in 1895 had also turned out to 
be another synonym. This is not the case, for all the specimens 
forwarded agreed in possessing fifteen pairs of legs only and 
thus differed from the form described above. Thus after nineteen 
years we have another record of the species Peripatoides occi- 
dentalis. 
There is no doubt, therefore, that there are two species of 
Peripatoides in West Australia. P. occidentalis resembles P. 
gilesii very closely in colour and the same variety occurs. Two 
series of individuals are common, a group in which brown-red 
predominates, and a group in which a green-black shade is the 
dominant colour. At present further investigations are being 
made and it will probably be" found that the two W estern Aus- 
tralian members of the Onyehophora are closely related to one 
another— perhaps only varieties of the same species.
