QUEENSLAND MOLLUSCAN NOTES, No. 1. 
By Tom Iredale.* 
(Plates XXX-XXXI.) 
Twenty years ago, as his Presidential Address to Section D, Biology, of 
the Australasian Association for the Advancement of Science, at a meeting held 
in Brisbane, my predecessor, the late Charles Hedley, discussed the Marine 
Fauna of Queensland, contributing a delightful historical sketch of its investi- 
gators, and giving as an appendix a Catalogue of the Marine Mollusea of 
Queensland. This catalogue has served its purpose well, and it is now time it 
should be replaced by a more comprehensive and down-to-date list. Such a list 
I am now compiling, and the present series of notes is explanatory of the 
additions and emendations to be made. 
Immediately upon publication of Hedley ’s list, Dr. J. Shirley placed on 
record a large number of “Additions/ ' but these have to be ignored by scientific 
workers, as they were based upon parcels of shells received from children, and 
included foreign shells: no discretion was utilised by Shirley, and many marine 
shells were recorded from inland localities. 
Hedley and McCulloch had made a large collection at Murray Island in 
1907, and this has never been reported upon. Later, McCulloch collected on 
the outer portion of the Great Bander Reef, and Hedley secured many species 
in his later short trips on the Barrier. 
The Rev. Percy Hubbard has been vigorously collecting mostly on the 
mainland coast near Innisfail, and has brought to light many interesting species. 
It is noteworthy that the mainland littoral fauna is at present not so well known 
as that of the reef. 
Mr. Melbourne Ward, interested in the study of Crustacea, has never 
neglected to make good collections of shells from the Capricorn Group, the Torres 
Straits Islands, and the islands of the Whitsunday Passage. Notes on his 
collections are here included. 
My colleague Mr. G. P. Whitley and 1 collected vigorously at Michaelmas 
Cay, off Cairns, in 1926; and calling at Caloundra, South Queensland, on our 
way back, met with an enthusiastic collector, Mr. C. Nicholson, and made such 
interesting finds that a note was written on the Caloundra shells. Last spring 
(1928) I was on Low Island, off Port Douglas, North Queensland, and a separate' 
report is being prepared on tin 1 collection there made, but the experience and 
material has been utilised in this essay. 
The Marine Mollusea n Fauna of Queensland is composed of three diverse 
faunulas, the coastal and the reef faunas, tin* former being divisible into a 
northern and southern portion. The southern area, which includes Moreton 
Bay, exposes a faunula very like that of the Sydney district, New South Wales, 
but with a larger element of tropical forms. The northern area is characterised 
by mud-living species which range round Cape York and the Gulf of 
Carpentaria, and as a whole is very distinct from that of the coral reefs lying
