Cover images —In 1998 the Australian entomologist and 
geologist Chris Muller reached the highest peaks of the very 
remote Schleinitz Mountains of Central New Ireland. Among 
the many remarkable and unknown insects, he collected a 
new butterfly species Cethosia vasalia Muller, 1999 (left, front 
cover) and in his description of it in the Records of the Australian 
Museum 51(2), he compared it to the two subspecies of C. 
obscura discovered more than 100 years earlier elsewhere in the 
Bismarck Archipelago: C. obscura obscura Guerin-Meneville, 
1831 (middle, front cover) and C. obscura antippe Grose-Smith 
& Kirby, 1889 (right, front cover). This work and others by 
Muller may be read online at the Australian Museum website:

The Australian Museum houses some of the world’s most important 
collections of Australian animal, fossil and geological specimens 
and cultural objects. Research on these millions of specimens and 
artefacts yields insights into how our world changes through time and 
how its diversity can be classified and interpreted. This knowledge, 
when shared among the scientific and broader community—initially 
through publication—helps us understand human impact on our 
environment and what reasonable steps society can take now for 
the well-being of future generations. Our responsibility is to inspire 
the exploration of nature and cultures; our vision is a beautiful and 
sustainable natural world with vibrant and diverse cultures. 
Since 1889 the Records of the Australian Museum (ISSN 0067- 
1975) has published the results of studies that derive in large part 
from Australian Museum collections or studies that more generally 
lead to a better understanding of nature and cultures in the Australian 
Region. Three issues of the Records are published annually and 
circulated to numerous countries. All that is published in print 
is, within several days, also freely available online. Records of the 
Australian Museum , volume 62, was published in 2010, volume 63 
in 2011. Monographic works of particular significance are published 
irregularly as Records of the Australian Museum, Supplements, the 
last in 2006. Catalogues and checklists have, in the past, been 
published in print as numbered Technical Reports of the Australian 
Museum (ISSN 1031-8062 print). From number 20 (December 
2007) onwards, Technical Reports of the Australian Museum, Online 
(ISSN 1835-4211 online) has been published online only. Australian 
Museum Memoirs (ISSN 0067-1967) ceased in 1983. 
Librarians or publishers of similar scientific and academic 
journals may propose exchange agreements with the Australian

special meaning for the 
Australian Museum as it 
represents both nature
