210 STUDIES ON AUSTRALIAN MOLLUSCA, VIII., 



On the dates of Tenison Woods' Tasmanian Shells. 

 In some cases G. F. Angas and Tenison Woods described the 

 same shell almost at the same time. It is therefore important to 

 ascertain the exact dates of publication of Tenison Woods' Tas- 

 manian shells. While on a visit to Hobart, I called on the 

 printers to the Royal Society of Tasmania, who most courteously 

 furnished me with the following dates of their Proceedings : — 



Proc. R.S. Tas. for 1874 issued May 11, 1875. 



The volume for 1877 was held over for a considerable time to 

 complete certain tables. Probably Tenison Woods circulated his 

 reprints privately before the appearance of the Proceedings. 



In the author's reprint, but not so far as I am aware in the 

 volume proper, there is inserted in reference to p. 135 of Proc. 

 Roy. Soc. Tas. for 1875, a slip dated 18th May, 1876, withdrawing 

 Trophon clathratus in favour of T. petterdi.
