carefully examined by ray friend, Mr. T. Rupert Jones, so 
well known for his researches in that branch of palaeontology. 
The various Foraminiferae were inserted in the last edition 
of Professor Morris' Catalogue of British Fossils, and the 
Entomostraca have been described and figured in Mr. Jones' 
Monograph, published by the Palseontographical Society for 
1856. According to him the species are as follows : — 
Dentalina communis. 
Lagena striata. 
Polymorphina lactea. 
Quinqueloculina seminulum. 
Robulina calcar ? 
Truncatulina tuberculata. 
and undetermined species of 
Biloculina. 
Guttulina. 
Nonionina. 
Triloc ul ina. 
Of these by far the most common is one of the species 
of Nonionina. The Biloculina, Triloculina, Quinquelocu 
lina, Polymorphina, and Guttulina are not so numerous, 
but still moderately abundant, whilst the rest are more rare, 
and especially the Lagena, of which I obtained only two 
specimens from the sand, not having found any in the sieved 
clay. 
All the determined species above named are found else- 
where. The Lagena, Polymorphina, Quinqueloculina, 
Robulina, and Truncatulina occur in a living state in 
British or European seas ; and the Dentalina, Quinquelo- 
culina and Truncatulina in the coral crag of Sutton, as 
made known by the researches of Mr. Searles V. Wood. 
As already mentioned, there occur in the washed clay 
many shells of Entomostraca. These belong to two species 
named by Jones, (Palaeontographical Society, Monograph on
