Praeger — The Marine Shells 



II. " The Natural History of Ireland," by "William Thompson : vol. IV., 

 1856. In this work 350 species and varieties of Marine Shells are recorded as 

 Irish, under the names which were in use prior to the publication of Forbes and 

 Hanley's treatise, of which some 240 are noted from localities in Ulster ; the 

 majority of these notes are given verbatim in the following pages. Mr. Thomp- 

 son's earlier list of Irish Shells, which appears in his " Report on the Fauna of 

 Ireland: Division Invertebrata," in the British Association Report for 1843, 

 contains many species not to be found in the "Natural History of Ireland"; 

 but it may be safely assumed that such were intentionally excluded from the 

 latter work, for many Shells had been recorded as native on very insufficient 

 grounds ; and the writer has, therefore, thought it best to be guided by the 

 ' ' Natural History' ' alone, as it contains all the notes which Mr. Thompson 

 considered thoroughly reliable.
