1)4 THE NAUTILUS. 



in Europe many years ago, togetlier with several otiiers illustrated in 

 tlie same work. 



• For anotlier new genus derived in part from tlie genus Clavilithes 

 of authors, the name ot" RhopuJithes is proposed (•' Genotype : Fusus 

 no{E Lamarck "), while three new species have been found in the 

 gleanings from the Paris Basin. The generic name of Oosmolitlies 

 is proposed for Fusus uniplicalus Lam. 



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

 Wlietiier a Pleurotomoid or a Fulguroid protoconch should remove a 

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

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

 Hemifiisics, 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 Avstkalian Mollusca. Part VIII. By C. 

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

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

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

 in nomenclature that should be adopted. The Strornbus urceus 

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

 urceus L. is rightly S. ustulatus Schumacher. Acvisea octoradinta 

 Hutton 1873, should be used in |)lace of tI. saccharina Linn., var. 

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

 and 14 new species are descril)ed. Lima sydneyensis is proposed in 

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



Notes on the Genus Sonokella, avith Descriptions of 

 New Species. By Paul Bartsch. (Smithsonian Miscellaneous 

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

 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- 

 tiiiirnishing t.ie genus from Eplpliragmopliora : the shell of Sonorella
