94 THE NAUTILUS. 



in Europe ninny years ago, together with several others illustrated in 

 the same work. 



For another new genus derived in part from the genus GlaviHthes 

 of authors, the name of Rhoprtlith.es is proposed (' Genotype : Fusus 

 no<z Lamarck "), while three new species have been found in the 

 gleanings from the Paris Basin. The generic name of Cosmolithes 

 is proposed for fttstts uniplicatus Lam. 



It is not easy to define the true position of many of the genera. 

 Whether a Pleurotomoid or a Fulguroid protoconch should remove a 

 shell in every other respect a Ftisus, from the family, or what posi- 

 tion a shell with the protoconch of a Fiisus, but with the form of a 

 Henrifusus, should occupy, the author has not always clearly defined. 

 A table of genera showing their relative position to allied forms 

 would have been very useful and would more readily convey to stu- 

 dents the author's conclusions. 



The work contains 192 pages, including 18 plates. The two plates 

 of protoconchs are exceedingly fine, but the half-tone plates could be 

 improved upon. C. W. J. 



STUDIES ON AUSTRALIAN MOLLUSCA. Part VIII. By C. 

 Hedley. With a Note on Terebra Hedleyi Tate. By Edgar A. 

 Smith (Proc. Linn. Soc. N. S. AVales, Pt. 1, 1904, pp. 182-212, 

 plates 8-10). The author has again brought forward some changes 

 in nomenclature that should be adopted. The Strombus urceus 

 Linn. == S. Jtoridus Lam. The species commonly known as S. 

 urceus L. is rightly S. ustuhitus Schumacher. Acmsea octoradiata 

 Hutton 1873, should be used in place of A. saccharina Linn., var. 

 perplexa Pilsbry, as suggested by Dr. Pilsbry. A new genus Stiva 

 and 14 new species are described. Linta sydneyensis is proposed in 

 place of L. brunnea Hedley not Cook. C. W. J. 



NOTES ON THE GENUS SONOKELLA, WITH DESCRIPTIONS OF 

 NEW SPECIES. By Paul Bartsch. (Smithsonian Miscellaneous 

 Collections, vol. 47, part 2, Oct. 10, 1904.) This study deals \\itli 

 a group of Southwestern Helices, nearly all of which have been de- 

 scribed since 1890 ; and the foundation of the genus dates only from 

 1901. To the anatomical characteristics already known, Mr. 

 Bartsch adds a very useful conchological generic character, dis- 

 tinguishing t.ie, genus from Epiphragmophora : the shell of Sonorella
