study of which, is not generally pursued by conchologists. I will allude 

 to them separately. 



The additions to our lists of species of marine mollusca are recorded 

 in the following works and papers : — A. Adams, in Sowerby's " Thesaurus 

 Conchyliorum," describes three species of Atys from Port Lincoln ; and 

 "Reeve identifies two species of Cyclostrema from the same locality with 

 previously kno svn Japanese shells. These and the foregoing species are 

 described and figured in Reeve's " Iconica Conch." 



Mr. T. Bednall, in a " List of South Australian Marine Shells," 

 privately printed 1874, inserts thirteen gasteropods and three bivalves 

 not previously known to occur with us. 



A census of the marine gasteropods, bivalves, and brachiopods of 

 : Tasmania and the adjacent islands (Proc. Roy. Soc. Tasmania, 1877), is 

 the work of the Rev. J. E. Tenison "Woods. It bears evidence of con- 

 siderable labour spent in its preparation, as it contains all the species 

 recorded by previous authors, and all the new species, which are many, 

 described by Mr. Woods in two papers published by the same Society ; 

 and the claims of critical and doubtful species are discussed. Those 

 interested in the distribution of the constituents of the marine fauna of 

 Australia will find this production of great service. The horizontal 

 range of some of the species is indicated; but the omissions in this 

 respect are unfortunately many, and the comparative unity of the Tas- 

 manian fauna is rendered more apparent than real. Mr. Woods makes 

 known the occurrence of eleven gasteropods and one bivalve in the south- 

 eastern part of our coastline, which are not mentioned as South Aus- 

 tralian by previous observers. He has also corrected the names of some 

 of our species. 



The same author, in a paper "On some new Marine Mollusca," 

 Roy. Soc. of Victoria (1877), states on my authority that Pectunculus 

 laticostatus, so abundant in a fossilized state in Southern Australia and 

 Tasmania, is living in St. Vincent's G-ulf. 



Angas, Proc. Zool. Soc, March 1878, adds two species of Mitra and 

 one of Siphonaria to the local fauna — the three are new to science. 



In the pages of this volume will be found a small contribution by 

 myself to South Australian conchology. 



Mr. Angas is now publishing in Proc. Zool. Soc. an appendix to his 

 list of 1865. From material received from me he adds fifteen known 

 species of gasteropods and seven of bivalves to our fauna, and describes 

 as new to science seven species of gasteropods and four of bivalves. A
