Vn. FORAMINIFERA OF THE LONDON CLAY FROM A WELL 
AT HAMPSTEAD HEATH. (See pages 19-21.) 
The specimens from the London Clay of the Well at Hampstead (WethereU 
Coll.) were collected many years ago (in 1833), and were described and figured 
by J. de C. Sowerby, in the 1 Transactions of the Geological Society of London,’ 
ser. 2, vol. v. p. 135, pi. 9. figs. 3-20. They were accompanied by other minute 
fossils, also described and figured at the same time. Some of these remain 
associated with the Foraminifera in the collection. 
In the ‘ Geologist,’ vol. vii. 1864, pp. 85-89, these Foraminifera were reviewed 
by Parker and Jones ; and the nomenclature was determined as follows : —

(See pages 21-26, 29-43, 45-52, 56.) 
1. Note on the Name “ Nummidites.” 
Lamabck and other French naturalists adopted, to a great extent, the plan of 
naming recent Foraminifera with the generic name ending in ina, and the fossil 
genera with the name ending in ites — as Lenticulina and Lenticulites &c. ; and
