In beds Nos. 1 and 3 I have found neither Foraminifera nor other 

 fossils ; but beds Nos. 2 and 4 are ver}^ rich. In fact these two beds 

 here form the most fossiUferous zone oi Ammonites angulatus. They 

 are composed of rubblj' irregular limestone, often crowded Avith frag- 

 ments of shells; and from the heaps of them at the pit -side I have 

 obtained the following fossils : — 



Plesiosaurus (tooth). 



Acrodus minimus {Ag.) (tooth). 



Ammonites angulatus (Schl.). 



Johnstoui (Sow.). 



Nautilus striatus (Sow.). 

 Trochotoma striatum {Horn.). 

 Pleurotomaria nucleus ( Tcrq.). 

 Phasianella Morencyana {Terq.). 

 Littorina elegans (Gldf.). 

 Melania unicingulata [lerq.) 

 Turritella Dunkeri (Terq.). 

 Cerithium semele {JD' Orb.). 

 Saxicava arenicola (Tcrq.). 

 Ai*comya elongata (Bom. sp.). 

 Pleuromya galathea (Ag.).

Astarte Guenxii (D' Orb.).

Bed No. 5 is more sandy and lighter-coloured at the top, and gra- 

 dually changes to a soft laminated clay without any distinct line of 

 demarcation. The same fossils occur throughout as indistinct im- 

 pressions. They are the following : — 



TJnicardium cardioides {Ph. sp.). 

 Lucina ovula {T. &f P ). 

 Protocardia Philippiana {Pkr.). 

 Cardium profundmn (n. s.). 

 Cucullasa hettangiensis [2'erq. sp.).

The Foraminifera are very abundant, and form a different set in
