rock ill his shaft, for there is every probability of " payable " 

 auriferous wash being fomicl beneath the massive layer. 



In conclusion, while sincerely rejoicing at the prosperous 

 condition of several of the gold mines of Tasmania, I cannot 

 contemplate but with serious misgiving the " mining mania " 

 that has apparently seized the Tasmanian public, especially 

 in the North. Eash investments in mythical quartz reefs is 

 not legitimate mining, and can only lead in many instances 

 to disaster, as happened at Hill-end and Tambaroora, in 

 New South Wales, some few years back. 



I sincerely hope it will not be so ; but would wish to see 

 every confiding shareholder gladdened by dividends to his 

 heart's content. 



There can be no doubt that Tasmania has unbounded 

 wealth in her mines ; and I feel assured that in their deve- 

 lopment she has the means of rising, Phoenix-like, from the 

 ashes of her former comparative poverty to a dazzling height 

 of permanent prosperity. 



TYPE SPECIES OF TASMANIAN SHELLS UNRE- 

 CORDED IN THE "CENSUS OE TASMANIAN 

 SHELLS." 



By Professor R. Tate, Assoc. Lin. Soc, F.Gt.S., &c. 



[Mead Ut/i June, 1881.] 



Having, in the course of my researches in the bibliography 

 of Australian Mollusca, noted that some specific names, 

 founded on Tasmanian types, are not referred to in the con- 

 chological papers contained in recent issues of the Society's 

 transactions, I have thought some utility may be served by 

 their publication. They are not necessarily addenda to the 

 " Census " by the Rev. J. E. Tenison- Woods, as it remains 

 to be ascertained whether they are applicable or not to good 

 species, and if to good species then whether they have priority 

 or not over others already enumerated in the " Census." 

 This task I relegate to the author— a " Revised Census." 



To the following list I have appended references to the 

 authorities for the specific names, and the localities of the 

 type-specimens : — 



CoLUMBELLA ROSACEA, Bccve, Icoii. Couc, (?) — 0. semlcon- 

 vexa. Tasmania. 



Cbrithium Diemense, Quoy and Gaimard, Voy. Astrolabe 

 to 55, f. 13-13. Tasmania. 



Cerithium dubium, Sowerhy, Mes. Con., sp. 62 ; and Uceve^ 

 Icon. Con. t. 12, f . 78 (has priority over C. monachuSj 

 Tasmania.
