(1) Fossil species have been found in the Id Fresh Water Formations of the en- 

 virons of Paris. The marine species at Grignon have not the same generic cha- 

 racter as the Bulimi, according to Brongniart, and ought to be referred to the 

 Phasianellae. Lamarck has observed that only terrestrial shells have the lip reflected. 

 The Bulimus dombeyanus , B. octronus^ and B. terebrasler, pi. 13, fig, 15, and many 

 other species which inhabit Asia, Africa, or America, are turreted with numerous 

 whorls ; others are of a conical form, as the Bulimus trochoides of Bruguiere, See the
