30 TAYLOR: ON NEW VARIETIES OF BRITISH SHELLS. 



from Portishead, both places situate in North Somerset. 

 I have also a specimen from Galway presented to me 

 by Mr. Nelson and Mr. A. H. Cooke records it in the 

 Mac Andrew collection from Dublin. 



Helix virgata var. subalbida Poiret. Shell white, with one 

 band above the periphery. 



Dr. H. Franklin Parsons kindly gave me two 

 specimens collected by him in East Somersetshire. I 

 have also specimens from Tenby, collected by Mr. 

 Poland. 



Helix virgata var. nigrescens Grateloup. Shell nearly 

 uniformly dark blackish-brown, from the coalition and 

 diffusion of the markings. 



Mr. J. W. Wood of Northampton collected this 

 variety at Freshwater, I. of W., in 1875. I am also 

 indebted to Mr. Ashford for specimens from Yarmouth, 

 Isle of Wight. Dr. Gray was aware of the occurrence 

 of this variety in Pritain, remarking (I.e. p. 161) 'some- 

 times the coloring which forms the bands is suffused 

 over the whole shell, making it brown, or even nearly 

 black.' 



Helix caperata var. obliterata Picard. Shell white, with 

 translucent markings. 



Mr. Lister Peace has collected specimens of this 

 variety at Paine Moor, near PoUington, Yorks., and 

 I am indebted to his kindness for specimens of this 

 and its allied variety. 



Helix caperata var. alba Picard. Shell pure white without 

 markings. 



Mr. Peace was fortunate in finding this variety 

 in company with the last.
