of protoconchs found in the Western Australian specimen was forty-seven, but 
they were in a very advanced stage of development, on the point of hatching, and 
presumably about half of them had already left the capsule. 
The Southern Australian Baler is found during summer and in certain definite 
areas, in groups of forty to fifty. The male is readily distinguished by its smaller 
size and slightly different shape. Fishermen frequently refer to the male and female 
as representing different species. We have records of living examples from Point 
Brown, Bell Sinclair and Smoky Bay (all on the West Coast of South Australia). 
This constitutes the first authentic though brief observations on this interesting 
molluse and since the time and place of breeding is now known further observations 
will probably be made.
