Having in the course j last bos years dida in ob- 
taining from the Upper Tertiaries of Great Britain a consider- 
able number of species of shells, Echini, &c. that have not yet 
been recorded, the following list of those procured from the 
different Crags may be useful to others who are interested in 
the study of these deposits. 
Those species marked thus * are new to the Crag fauna (and 
will be figured shortly from these or other specimens); the 
others are simply EU to the strata to which they are referred. 
he terms C. C., R. C., N.C., Chil. ser. are used as contrac- 
tions of. Coralline ‘Crag, "Red Crag, Norwich Crag, and the 
Chillesford series respectively.
