G. " Ilhistrations of the Land and Fresh-water Conchology of Grent 



Britain and Ireland." London, 1845. 8vo ; pp. xi, 142, 27 pis. 



In which book is advertised : — 

 6a. " Illustrations of the Land and Fresh -water Conchology of the 



British Islands." Svo ; 27 pis. And : — 

 6b. " Illustrations of the Land and Fresh-water Shells of Ireland." 



Svo ; 18 pis., both as " published." 



These three seem to be different advertisements of the same 



work, of which the first (6) appeared. 



7. "A Catalogue of the Kecent Conchology of Great Britain and 



Ireland." Price one shilling. 



8. " A Catalogue of the Land and Fresh-water Shells of Great Britain 



and Ireland." Price sixpence. 



These two last are for the purposes of labelling collections. 



It is curious how I'arely any contemporary reference is found to 

 these books The same remark applies to their author. Captain 

 Brown's history is so imperfectly known that it would be difficult 

 to sti'ing together any running storJ^ He is not referred to in the 

 Dictionary of National Biography, and this not merely by oversight 

 so far as the Supplement is concerned. The putting together of these 

 notes must be regarded as a first attempt, and no one will welcome 

 further information more gratefully than the writer.
