There is a tendency for our knowledge of the species of Peri- 
patus in Western Australia to become somewhat confused. Three 
species have been described, namely :— 
I. Peripatus leuckarti, var. occidentalis. 
syn. Peripatoides occidentalis. 
II. Peripatoides giles Spencer. 
Ill. Peripatoides woodwardi Bouvier. 
Of these three, Peripatoides occidentalis was the first to be 
made known. ‘The species was described by Fletcher, from speci- 
mens collected by a Mr. Lea at Bridgetown, South-Western 
Australia (Proc. Linn. Soc. N.S.W. 1895 (2), x.). The diagnosis 
reads as follows:—* P. lewckarti Sing, var. occidentalis, var. nov. 
With 15 pairs of walking legs; outer jaw-blades without an 
accessory tooth.” 
Beyond a brief reference to the colour, no further description 1s 
given and unfortunately no figures accompany the paper. 
Twelve years later, Peripatws was found in another locality 
(Armadale) in Western Australia, not far from the capital, 
Perth, and specimens collected by Mr. H. M, Giles were sent to 
Professor Baldwin Spencer. The latter considered them to belong 
to a new species, and, in a short paper read September 1908 (but 
not published until March 1909), named the species Peripatoides 
gilesii after the collector *. 
In the year 1905, however (that is two years before the speci- 
mens were sent by Giles to Spencer), the German Expedition of 
Michaelsen and Hartmeyer captured a number of Peripatus at 
Lion Mill, a place also near Perth. These specimens were sent to 
Bouvier, and his description with an account of the anatomy was 
published in the Reports of the Expedition in 1909+. Bouvier 
recognised these specimens as belonging to a new species, which 
he named Peripatoides woodwardt. 
It will be noted here that the appearance of the papers of both
