 So many Australian shells were named by Lamarck, that his 

 collection has a special interest for us. The Lamarckian types 

 are divided between two cities. Some are contained in the 

 collection of the Museum of the Jardin des Plantes, once under 

 his official care. These are now gathered together, in a room 

 apart, in the Paris Museum.* 



The others, included in Lamark's private collection, had a more 

 eventful history. At the sale of Lamarck's books and specimens 

 in 1830, the shells were purchased by the Prince Massena, due 

 de Rivoli. Afterwards these were transferred to Baron Benjamin 

 Delessert, a wealthy Parisian merchant. It is recorded that 

 Lamarck's conchological collection contained 13,288 species, 

 represented by about 50,000 specimens.! 



Baron Delessert enlarged his collection by other acquisitions,; 

 and appointed first Kiener, and then Chenu as Curator. From 

 the Delessert Museum, a series of monographs, embracing the 

 whole conchological field, was projected, commenced by Kiener, 

 and, after his death, continued by Chenu. But this magnificent 

 scheme collapsed in 1854, after the issue of a number of broken 

 parts. § 



Upon the death of the owner, his brother, Baron F. Delessert, 

 inherited the Collection. At his decease, the heirs presented the
