THE POST-PLIOCENE NON-MARINE MOL- 

 LUSCA OF ILFORD, ESSEX. 



By A. S. KENNARD and B. B. WOODWARD, F.L.S., F.G.S. 



IN 1897 the Non-Marine Mollusca from the Pleistocene 

 deposits at Ilford were described by us in the Essex 

 Naturalist.' Since then Mr. Martin A. C. Hinton has collected 

 extensively in the Cauliflower Pit and his specimens were placed 

 at our service. All the old collections were made in the Uphall 

 Pit, where the shells were abundant, but in the Cauliflower Pit 

 they are scarce, and it is by no means uncommon for a diligent 

 search to yield only two or three specimens. As we noticed in 

 our previous paper, Dr. Corner's examples were also obtained 

 from this latter pit, and from these two collections we are now 

 able to list thirty-four species from this pit, viz. : — 

 Vitrea nitida (Miill.) 



,, nitidiila (Drap.) 

 Vallonia pulchella (Miill.) 

 Ilygromia hispida (Linn.) 

 Helicigona arhustonnn (Linn.)

 Helicella virgata (Da Costa) 



,, caperata (Mont.) 

 Pupa cylindvacea (Da Costa) 



,, mnscornm (Linn.) 

 Vertigo antivertigo (Drap.) 

 Succinea piitris (Linn.) 

 ,, elegans Risso 

 LtimiiFa pevegey (Miill.) 

 ,, palustris (Mull.) 

 ,, truncatula (Miill.) 

 ,, stagnalis (Linn.) 

 ,, glabra (Miill.)
