GEOLOGY OK KOI-KESTONE — THE GAULT. 325 
graceful Scalaria Olenicntiiia, or a handsome Scalariu Dup'miana 
may be exhumed in the same lucky manner. Of the genus Scalaria 
four or five other species arc recorded as occuring in continental 
localities ; of these I believe I have found fragments of the following 
bign. 35. — Scalaria clementinn . Lign. 36. — Cast of Scalaria Dupitiiaua, 
with restored outline of month. 
at Folkestone — S. gaultina, S. Bauliniana, 8. gastma, but I can not 
speak with certainty. 
These forms should therefore be looked for by collectors, as should 
also a little Rissoa, a genus familiar most likely to some of our 
readers, from the immense abundance of a living species in the pools 
of sea-side marshes.
