Bibliographical Notice. 139 



It seems clear to me that Linnaeus regarded it as a new genus 

 like Area and Pinna. None of the shells here described are 

 mentioned in any of his later works. 



Tectura, Aud. and M.-Edw., is named and described in the 

 ' Compt. Rend/ for 1824. In the ' Hist. Nat. du littoral de la 

 France/ it is characterized by the gills as a new genus, but not 

 named. 



I will conclude with a few bibliographical observations. 



The name of the person who writes a work is a matter of 

 perfect indifference to science, and is only necessary for the pur- 

 pose of distinguishing the work. To the public, each work or 

 edition is as it were a different person. 



The ' Museum Boltenianum : was originally written by the 

 possessor of the collection, a pupil of Linnaeus, with additions 

 and corrections by P. F. Roding and Dr. Schultze, as appears 

 from the preface furnished by Ant. Aug. Hy. Lichtenstein. 

 I. C. Fabricius mentions, in the ' Mem. of the Nat. Soc. of Copen- 

 hagen/ 1793, vol. iii. p. 153, that the most important work of 

 Schultze was the arrangement of Bolten's collection, but which 

 he would probably never be able to complete. Bolten's work 

 was subsequently much used by Link, Lichtenstein in the Du- 

 plicate Catalogue, and Schumacher. The work, of which there 

 are two editions, is far from rare. 



Link's ' Verzeichniss' was burnt either by accident, as Herr- 

 mannsen (on the authority of Beck) states, or by the author ; 

 but a copy was preserved at the University of Rostock, which 

 copy has been recently brought to light by the researches of 

 conchologists. The author would not, according to Troschel, 

 acknowledge his work ; but no author has a right to repudiate 

 that which has been once published.

Considering the number of guides who have within the last few 

 years endeavoured to lead our sea-side pleasure-seekers to find a purer 

 and more intellectual enjoyment than that presented by the ordinary 

 course of existence at watering-places, in the investigation of the 

 wonders which Nature has lavished with a prodigal hand on every 

 shore, it must be confessed that the apparent effect produced is very
