Plate III. 
The present collection contains only 4 species of Alleculidae, 
all of which are new, and which do not readily conform with 
any known genus. The author adds to the descriptions of these 
new species those of two new species in his own collection. 
Homotrysis grandis, n. sp. — W. Australia (in the author’s collec- 
tion). 
obscura, n. sp. — W .Australia (in the author’s collec- 
tion). 
Dimorphochilus apicalis, n. gen., n. sp. — Torbay. 
diver sicollis, n. sp. — Northampton, Day Dawn, 
Yalgoo. Eradu, Kalgoorlie, Boorabbin, Cran- 
brook. 
sobrinus, n. sp. — Dirk Hartog, Brown Station. 
Oocistela convexa, n. gen., n. sp. — Fremantle.

The Aranean fauna of Western Australia has certain charac- 
teristics in common with those of other parts of the Continent. 
Some typical species: Delena cancerides (Walck.), A icodcimus 
bicolor (L. Koch.), etc., are as common here as elsewhere through- 
out Australia. 
Other very distinctive groups, Hemicloea, l.ampona, Isopoda, 
etc., are equally rich in W.A., but generally represented by other 
species. Among the Homocloeinae we have to note the new genus 
Corimaelhes, which is closely related to Plutyoides, of South Atiica, 
the only genus of the group outside of Australia. In the family 
Avicularidae the new genus Proshermacha also very much resembles 
the South African genus Hermacha, and the genus Synothele, the 
genus C estotrema of Madagascar. 
On the other hand, we do not find in Western Australia the 
affinities to the Malayan fauna, which are so numerous in Queens- 
land and especially at Cape York, in the North. 
Here follow various notes concerning systematic and biolo- 
gical relations of which only the latter are of general interest. 
^ The spiders of the new genus Phryganoporus differ from the 
allied typical Amaurobius not only in peculiarities of structure
