 as the Cambrian epoch. 



' At each centre visited, the zoologists of the party 

 were in close touch with the professor of the subject 

 at the University and other local workers, and many 

 of the excursions, both those in the official programme 

 and others of a more informal character, were arranged 

 so as to show the visiting specialists as much as 

 possible of the Australian fauna. At Perth, in 

 addition to the definitely zoological excursions to the 

 Yallingup caves and to the Mundaring Weir . ; .,<* 

 a few of the zoologists [visited] points of interest 

 on the Darling Eange, where Peripatus and other 

 important organisms were found. From Adelaide 

 parties of zoologists made observing and collecting 

 trips to Lake Alexandrina, Victor Harbour on the 

 coast, the Mount Lofty Range, and elsewhere, at all 

 of which objects of interest were seen and much 

 material collected which may lead to research. At 

 Melbourne the local naturalists arranged several 

 short trips in the neighbourhood to study the birds 

 and the land fauna generally ; while at Sydney the 

 excursions were naturally rather of a marine biolo- 

 gical character. ... A collecting party in Port 

 Jackson [explored] from a steam launch the wonder- 

 fully rich invertebrate fauna exposed at low tide in 

 various parts of the harbour. From Sydney, again, 

 the various excursions to the Blue Mountains and 

 the Jenolan Caves gave zoologists the opportunity of 

 collecting such rare and interesting forms as Peripatus 

 and land Planarians and of seeing many of the 

 characteristic birds and insects of the country ; 

 and the same may be said of some of the excursions 

 from Brisbane. At the museums and University 

 laboratories of Perth, Adelaide, Melbourne, Sydney,
