[Eead 12tli June, 1902.] 



A former paper^ on the Geology of this locality was read before 

 this Society on 13th December, 1900. It was stated therein" 

 that, at the eastern end of the new cutting on the 

 northern side of the river, a stratum of " black fissile clay, with 

 three thin laminae of comminuted shells, and lenticles of pure 

 sand, 3 feet to 4 feet 6 inches " in thickness, overlay basalt, being 

 separated from it by a bed of sandy clay. It was, also, mentioned 

 that a small parcel of the shelly material, collected from this clay 

 bed, had been mislaid. This collection has, fortunately, come to 

 hand again, and careful examination of the material has enabled 

 -a few of the shells to be identified. 1 am indebted to Mr. J. H. 

 Gatliff, and Mr. J. Dennant, F.G.S. , F.C.S., for kindly determin- 

 ing them. The shells were so decomposed that even with the 

 greatest care only a few specimens could be obtained in good 

 ■order. These prove to be chiefly of lamellibranchs. 

 The list of those obtained is as follows :— 



Nassa labecula, A. Adams. 



Tatea rufllabris, A. Adams. 



Sphaerium ( = Cyclas) McGillivrayi, E. A. Smith. 



Corbicula sp. 



Mactra sp. 

 The greater number of the fragments consist apparently of 

 those of Corbicula. Of the two gastropods, one entire specimen, 

 and several fragments of Nassa were found ; while the small 

 Tatea rufilabris occurred rather sparingly.
