June, 1939 The Queensland Naturalist 
47 
when the log was turned over. The outstanding find was 
four specimens of Peripatoides leuckarti Sanger, two 
mature and two half grown. In 1936 three specimens 
were found so that the Upper Albert River is evidently a 
good locality for these rare and interesting Arthropods. 
A handsome species of Opiliones was fairly numerous. 
The Opiliones are close relatives of the spiders from which 
they differ in having a segmented and non-petiolate 
abdomen. The very long legs and hard body are very 
characteristic of these rather rare Arachnids. The 
identity of the species has not yet been established, and 
probably it will be necessary to send specimens to Europe 
for identification. 
Millepedes and centipedes were common under the 
stones and logs. Several specimens of Symphyla belong- 
ing to the family Scutigerellidae were found. These very 
primitive, fragile Myriapoda were not common, and con- 
siderable patience was required to collect them without 
injury. 
Practically no attempt was made to collect the insects 
of the rain forest, and perhaps more attention will be paid 
to them on some future occasion. The locality is an ex- 
cellent one for the naturalist and w r ell worthy of another 
trip.

NOTES ON PERIPATOIDES (PERIPATUS) 
LEUCKARTI SANGER. 
By F. A. Perkins, B.Sc.Agr. 
During the last few years the members of the 
Naturalists’ Club attending the Easter Camp have ex- 
pressed their surprise at the interest in Peripatus shown 
by the zoologists. It is fairly obvious that they have 
very little knowledge of this interesting animal, a sad 
state of affairs in a Naturalists’ Club. 
Th genus Peripatus was described in 1826 for some 
specimens from St. Vincent, and the author, Guiding, 
probably because of the slug-like appearance of the 
antennae placed it in the phylum Mollusca. Some of the 
later zoologists placed it in the phylum Annulata (seg- 
mented worms), and others in the sub-phylum Myriapoda 
(millepedes and centipedes). It is now generally agreed 
that its true place is in the phylum Arthropoda in a dis- 
tinct and separate sub-phylum known as Onychophora.
