BOULDER-CLAY AT BRIDLINGTON QUAY. 319 
APPENDIX A. 
By Dr. Gwyn JEFFREYS. 
List of Shells obtained from the *‘ Basement” Clay at Bridlington Quay. 
Observation.—The species which are not included in the list of 
Bridlington Post-Tertiary shells furnished by me to the late Professor 
Phillips, and published in the third edition of his ‘ Geology of York- 
shire,’ p. 274, and which are therefore for the first time recorded, 
are marked with an asterisk. Among these are five species new to 
science, which will be now described and figured. 
In the column after the names of species the letter A. signifies 
Arctic, Am. American, L. littoral or shallow water (2. ¢. under 100 
fathoms), D. deep sea (over 100 fathoms), and sp. n. new species.
