To complete the Lenham fauna 1 have here briefly introduced 

 a list of the other organic remains which are found associated with 

 the shells : — 



Pisces — Selachian vertehrK and a palatal plate as determined by 

 Dr. A. S. Woodward. 



Collection : B.M.' (Graham Wallas). 



Polyzoa — Fascicularia anrantium M. Edwards. 

 Collection : M.P.G. No. 398. 



Cupularia canariensis Busk. 

 Collections : M.P.G. No. 399. 



B.M. (Graham Wallas). . 



Annelida — Ditnipa subulata Deshayes, sp. 

 Collection : M.P.G. No. 395. 



Crustacea — [A decapod claw]. 



Collection : B.M. (Graham W^allas). 



Balanns. 

 Collection : M.P.G. No. 396. 



Echinodermata — Temnechinns ? 



Collection : B.M. (Graham Wallas). 



Echinus woodwardt Desor. 

 Collections : M.P.G. No. 394. 



B.M. (Prestwich and Graham Wallas). 

 Dorocidaris papiilata Leske, sp. 

 Collection : B.M. (Prestwich). 



Actinozoa — TrochocyatJms (?) 



Collection : B.M. (Graham Wallas). 



In addition to these organisms the Lenham sandstones occasionally 

 exhibit impressions of the spines of Cidaris davigera Konig, and 

 remains of Inoceramiis-'&\\€i\ associated with the sponge, CHona, all 

 of which belong to the chalk (Senonian) formation, and are conse- 

 quently of derivative origin. No trace has been discovered in these 

 beds of any fossils which could possibly have been derived from 

 Eocene rocks. 



In concluding this preliminary statement, I should wish to acknow- 

 ledge my gratitude to the authorities of the Museum of Practical 

 Geology for allowing me access to the "Rcid" Collection, and 

 particularly to Mr. H. A. Allen, F.G.S., of that institution for facili- 

 tating most of the arrangements in connection therewith. 



I Note. — The letters B.M. and M.P.G. throughout this work apply respectively to the
