In 1823. J. G. Children, an assistant keeper in the British Museum, 

 pubHshed a small work entitled " Lamarck's/Genera of Shells,/ Trans- 

 lated from the French,/ By/ J. G. Children, F. R. S./ &c.&c.&c./ 

 With Plates/ From Original Drawings,/ By Miss Anna Children./ 

 1823./ " 



This little work, now very rare, first appeared serially, without the 

 author's name, in the successive numbers of the Quarterly Journal of 

 Science, the official organ of the Royal Institution of Great Britain, 

 of which at the time Children was editor, between October, 1822, and 

 January, 1824, as follows:

Two plates were issued with each of the first four parts and were 

 not renumbered for the reprint. The references in the text of the 

 third part to " PI. I " and " PI. II " should read respectively 

 " PI. II " and " PI. III." The last part was probably issued late 

 in December, 1823. 



The work consists of a translation of the diagnoses of the shell-bear- 

 ing genera in Lamarck's " Histoire naturelle des Animaux sans 

 Vertebres ", Tom. V-VII, 1818-22, with designation of a type to each. 

 These types are in most cases the first species cited by Lamarck him- 

 self, but frequently a species other than the first is chosen, occasionally 

 with reason given, or a species from some later work by another 

 author, showing that Children understood " type " in its modern sense. 

 Practically forgotten until attention was called to it in the Pro- 

 ceedings of the Malacological Society of London (\'ol. XV, 1922,
