In volumes xxiv. and xxv. of these Transactions I published 

 lists of the land and fresh -water shells found at various places 

 in this colony. More material having accumulated in my col- 

 lection, I now^ wish to publish some additional lists, thus help- 

 ing to enlarge the knowledge of the geographical distribution 

 of some of our Mollusca, which is still very far from satisfac- 

 tory. Most of our land-shells being minute or small, and 

 living concealed in the bush under logs, stones, dead leaves, 

 bark, &c., during day-time, it is not astonishing that much 

 remains to be done in the way of collecting, and that new 

 forms are still turning up when a careful search for shells is 

 made.

In volume xxiv. of the Transactions, pp. 277, 278, a
