ALBINO VARIETIES AT LEWES, SUSSEX. 

 By C. H. morris. 



(Read before the Conchological Society, April 12, 1S93). 



It may be of interest to record that I took three examples 

 of Plaiioibis spirorbis var. albida at Lewes last year. I have 

 also discovered Planorbis corne2isv:\x. albinn at Lewes. Neither 

 of these varieties I think have ever been recorded from Sussex. 

 We seem particularly well off for albino forms at Lewes. 



The following is a list of those that occur : — 

 Valvata piscinalis var. albina. 

 Planorbis spirorbis var. albida. 

 P. corneus var. albina. 

 P. contortus var. albida. 

 Limnaea palustris var. albida. 

 Hyalinia cellaria var. albina. 

 H. nitidula var. helnnii. 

 H. pura var. margaritacea. 

 H. aspersa var. exalbida. 

 H. nemoralis var. albina. 

 H. cantiana var. albida. 

 H. cartusiana var. lactescens. 

 H. rufescens van alba. 

 H. virgata vars. alba and albicans. 

 H. caperata var. alba. 

 H. rotundata var. alba. 

 Clausilia laminata var. albina.
