388 THE ZOOLOGIST. 



P. jenkinsi, Smith. — Frequenting brackish waters. Locally 

 abundant. Lewes (C. H. Morris, 1894, and more recently by 

 other observers) ; ditch at Litlington, near Eastbourne (A. G. 

 Stubbs) ; Pevensey Marshes (Eev. W. A. Shaw) ; in ditches 

 connected with the River Adur at Beeding (L. E. Adams, J. C, 

 xiii., 68). 



P. ventrosa, Montagu. — In brackish waters. Pevensey (A. J. 

 Alletsee) ; near Winchelsea, in ponds on beach (E. A. Butler). 



Var. pellucida, Jeffreys. — Thorney Island, plentiful (Rev. 

 W. A. Shaw). 



P. stagnalis, Basier (=Hydrobia ulvce, Pennant). — Frequenting 

 brackish water. Camber Sands 5 Rye (E. A. Butler) ; River 

 Adur, Shoreham (Rev. C. E. Y. Kendall) ; Bognor (H. L. F. 

 Guermonprez) ; Bosham and Pagham (Rev. W, A. Shaw). It 

 is probable that the species of Paludestrina recorded above are 

 widely distributed on the Sussex coast, though the records are 

 very few. 



P. marginata, Michaud. — It is recorded from Pleistocene de- 

 posits at West Wittering by Mr. J. P. Johnston. Extinct in 

 Britain, but surviving in France. 



Bithynia tentacidata, Linne". — Generally distributed. 



Var. ventricosa, Menke. — Common in the Levels, Lewes 

 (W. C. Unwin) ; marsh ditch near Camber Castle (Eastbourne 

 Nat. Hist. Soc). 



Var. albida, Rimmer. — Pevensey (Rufford collection, Hastings 

 Museum). 



Monst. decollata. — Canal near Alfold (E. W. S.). 



B. leachi, Sheppard. — Widely distributed. 



Var. albida, Rimmer. — Pevensey Marshes (Rev. W. A. Shaw). 

 A form with raised longitudinal brown stripes was found near 

 Pevensey by Mr. P. Rufford. 



Vivipara vivipara, Linne {— Paludina vivipara, L.).— Canals 

 and sluggish streams ; rare. Pevensey Level and the marsh 

 drains between Siddlesham and Selsea (J. E. Harting, as doubt- 

 ful). " The only recorded locality for this shell is the River 

 Arun (W. Borrer, in 'Zoologist,' 1878). I found it numerous at 

 Wisbro' Green in 1877 in a ditch supplying the Wey and Arun 

 Canal. It probably came from the Wey " (W. Jeffery). Bognor 

 (H. L. F. Guermonprez).
