In March, 1912, the Federal Minister of Trade and Cus- 
toms granted me permission to go on the trawler “Endeavour” 
during a trip of investigation in the Bight. 
The area covered extended from 30 to 120 miles west - 
of the longitude of Eucla, along the 100-fathom line, the 
trawl being taken across this line from 75 fathoms to 120 
fathoms. The 100-fathom line followed the curve of the 
coast fairly uniformly at a distance of about 60 miles. The 
shells obtained were those brought up incidentally in the 
large trawl when this was gathering fish. As its mesh was 
comparatively large, very few small shells were taken. The 
fauna was consequently quite different from that I have 
dredged off the South Australian coast in deep water before, 
when either a very fine-meshed net-dredge or, a conical iron 
bucket-dredge has been used, and only smaller forms have 
been obtained. Mr. Dannevig, the Director of the Fisheries 
investigation, very kindly gave me two hauls with my bucket- 
dredge in deep water, and so supplied me with material for 
comparison with what I have taken in a similar manner and 
at equal depths elsewhere. 
I am pleased to take this opportunity of expressing my 
thanks to the Ministerial heads of the Department in the 
Commonwealth and in the State for the opportunity of 
securing much interesting material, and also to the officers, 
and men on the trawler for their very ready and interested 
help. 
In this paper, owing to lack of time, I am only able to 
deal with the larger Gasteropods. I hope to deal with the 
smaller forms and with the Pelecypods in the future.
