1884. In the ' Fourth Annual Report of the U.S. Geological Survey ' for 1882-3, 

 issued in 1884, Ostreapatercula, Winchell, from the Kinderhook beds of Burlington, 

 Iowa, is figured (pi. xxxiv, figs. 1 and 2, p. 288) in a " Review of the Fossil 

 Ostreidge of North America" by C. A. White. 



1885. The fifth part, tome xi, of the ' Annales du Musee Royal d'Histoire 

 Naturelle de Belgique,' " Fanne du Calcaire Carbonifere de la Belgique : Lamelli- 

 branches," by L. G. de Koninck, was published in 1885, in the writing of which he 

 associated himself with Dr. Julien Fraipont, many of the species being described by 

 the latter; in such cases the initials J. F. are appended. 461 species of Carboni- 

 ferous Lamellibranchs are described and figured from Belgian strata, and of these 

 only 35 are recognised as occurring in England, 35 in Ireland, 18 in Scotland, 

 6 in Germany, 10 in Russia, 6 in America, 1 in France, and 1 in Australia ; or in 

 all only 77 species previously described are recognised as occurring in Belgian 

 strata — a very significant and curious result. The list of 461 species are divided 

 into genera which are classed as follows :
