ington, D. C, of Lichtenstein's Latin address to the reader in the 

 1798 edition. Also a translation of Roeding's German preface 

 to the same edition, and a translation of the preface of Johannes 

 Noodt to the edition of 18 19, when the work was reprinted for 

 use in disposing by auction of the collection. These German trans- 

 lations are due to the courtesy of Prof. Paul Bartsch of the 

 Medical Department of Howard University. To both these trans- 

 lators I am under obligations, for relieving me of any anxiety as 

 to the strict accuracy of my own rendering of the original into 

 English. 



Bolten's classification was purely conchological and based upon 

 form, rather than minor if perhaps more important characters.. 

 Yet it was far in advance as a natural system of any previously 

 proposed, including that of Linnaeus, which was at that time in 

 general use. It remained for the combined researches of Lamarck 

 and Cuvier, 18 years later, to propose a system based on anatomical 

 structure with results which in many cases confirmed those derived 

 by the acute intelligence of Bolten from a study of the forms of 

 the shells. 



The following abbreviations have been used for the titles of 

 works in which figures or names are referred to by Roeding. 



The relation of the Lamarckian and other modern specific names 

 to those of Bolten in the Index, is indicated by the serial and page 

 number of Bolten, which immediately follow the Lamarckian 

 reference on the same line. A review of the relation of the generic 

 names of Bolten to subsequently proposed names will be found in 

 the Journal of Conchology (Leeds), volume XI, No. 10, pp. 294- 

 297, April, 1906, where types are assigned to such as are not 

 already provided with them according to the rules of nomenclature.
