The species of land-shells detected in the loess^ in the speci- 

 mens sent, are : Helix alholahris, alternata, concava, elevata, 

 exoleta, gularis, hirsuta, inornata^ injlecta, ligera, monodon, 

 palliata, perspectiva, profunda, thyroidus ; Helicina orbiculata ; 

 Succinea ohliqiia. These are all existing species. Several of 

 them do not now inhabit the neighborhood of Natchez, though 

 they are very numerous on the banks of the more northern tribu- 

 taries of the Mississippi. 



In a small parcel of loess from the Wabash deposit. Dr. B. 

 found Helix dausa, hirsuta, infecta, lahyrinthica, lineata, thyroi- 

 dus ; Pupa armifera and coniracta ; Helicina occulta ; together 

 with several species of Limnea, Planorhis, Amnicola and Val- 

 vata ; — all at present existing in that region, except Helicina 

 occulta, a rare shell when recent, but very plentiful in its fossil 

 state, though it has been found alive in south-western Pennsyl- 

 vania. 



A careful examination of both deposits would no doubt bring 

 to view other species. 



Joseph Peabody, of Salem, and Frederick W. Davis and 

 Thomas Bailey, of Boston, were elected Members of the 

 Society.
