3o6 JEFFERY: the iMOLLUSCA of western SUSSEX. 



All the species have been submitted for identification to the 

 Conchological Society, and I am indebted also to my friend Mr. 

 H. Haines of West Ashling for much kind assistance and 

 co-operation during the past two years. 



Some fourteen other species are recorded as found in the 

 county of Sussex, viz: : — Sphceriufii rivicola (rejectamenta o 

 Arun), Bythinia Leachii, Planorbis carinatus, P. Hneafus, Li?/incea 

 glabra, Helix cartusiana, H. concinna, H. sericea ?, H. fusca, Pupa 

 secale, Vertigo antivertigo, V. edetitula, Azeca tridens and Acme 

 lineata (see Zoologist for 1878), 



With the exception of Helix fusca none of these have come 

 under my notice here. I found one example of this species, since 

 having had some sent me, which I obtained near here in 1880, 

 but am not quite certain as to the locality. 



On the other hand Limax arborum has been overlooked by 

 other observers, for although I find it far from uncommon and 

 even numerous in certain parts, it is not mentioned in any of the 

 local lists in the county of Sussex. 



AQUATIC. 

 Sphasrium corneum. Generally distributed : in the mud of 



ponds and ditches and occasionally amongst floating 

 weeds. The var. flavescens plentiful in the mill stream 

 at Burton near Petworth amongst and under water moss 

 and other vegetation, but not found in the mud as is 

 the typical S. corneum. They occur here literally in 

 masses and may be taken up by the handful. 

 S. lacustre. In similar situations as the last and equally well 

 distributed. Var. Brochoniana is found near Ratham. 



Pisidium amnicum. Perhaps pretty well distributed but not 

 numerous— not generally considered common in the 



J.C, iii., April 1882
