Part I,

[Read May 7, 1895.] 
It is proposed in the present paper to enumerate in order the 
species of the Families Muricide, Tritonide, and Fuside, as a 
contribution towards a complete catalogue of the recent gastero- 
pods of the Province of South Australia. Several circumstances 
have of late favored such an effort. (1.) The issue by Mr. D. J. 
Adcock in 1893 of “ A List of Species of Aquatic Mollusca of 
South Australia,” which provided local collectors with as accurate 
a catalogue of our shells as was then available. It has proved of 
considerable value, by enabling each conchologist to discover 
roughly what species he possessed not included among our known 
fauna. (2.) The formation of the Malacological Section of the
