The intention of giving the Text of a Descriptive Catalogue 

 OF Shells, by John Edward Gray, Esq. F.R.S. &c,, in com- 

 pany with these Conchological Illustrations, having been 

 abandoned, the names of the species figured in each part will now 

 be given with it, and, as complete a Catalogue as can be made 

 vdll be added in the course of publisliing each genus. Such Ca- 

 talogue will consist of the names of all the species that can be 

 ascertained, together with the localities and a reference to a 

 figure where any is known: and where there is no good previous 

 figure known, one will be given. A reference to the Author 

 whose name is adopted will be added, together with concise 

 descriptions of the new species. The Conchological Illus- 

 trations will thus form a very complete addition to Wood's 

 Catalogue of Shells.
