While searching for shells at Watson's Bay, Sydney, at the 

 lowest spring tide in October, 1893, I found in a deep rock pool 

 at extreme low water an old bottle, which on examination proved 

 to be quite full of small shingle and sand. I took it home and as 

 on a cursory examination, while washing the contents, small shells 

 seemed to be rather numerous, I determined to work them out 

 very carefully as a matter of curiosity. 



The result was very astonishing, as I found no less than 155 

 species of molluscs, with a total of 1376 specimens, of which 121 

 si)ecies were Univalves, 32 species Bivalves, and one Brachiopod. 

 Of these, fifteen species of Univalves appear to be undescribed or 

 new to science, and one species (Turhonilla tasmanica) is, I believe, 

 recorded from Port Jackson for the first time. At least two other 

 species are very I'are. 



I feel that the result of my examination will be of sufiicient 

 interest to conchologists to place it on record, and I hope it may 

 be an indication to some of a rich source of supply of material. 

 I have examined the contents of several bottles since, but none 

 of them approached this one in richness of molluscan fauna ; and 

 I can only conclude that it had lain undisturbed in the position
