Віхск Target Gully is the richest fossil bid in New Zealand, and in 
many ways is regarded as a type locality for the Awamoan horizon, it is 
necessary that its fauna should be thoroughly examined. Five visits have 
been paid to Oamaru localities, and some forty to fifty thousand specimens 
have ae obtained. Examination of these has shown that the existing 
list of fossil shells from this locality (13a)* is ar ase complete, and needs 
much revision in its nomenclature e present paper is a preliminary 
attempt to deal with this: it consists of lists "of new records from four 
Oamaru localities, and a series of notes on the necessary nomenclatural 
changes. A complete list of the Mollusca from Target Gully will be 
occasion 
The following species, not previously obtained from this locality, may 
now be added to the list. Where a name has been corrected, the old 
name is placed in square brackets after it. To facilitate reference the 
lists are in alphabetical order. An asterisk denotes a Recent ga 
Probably it will prove, when actual specimens have been compared, tha
