A New Variety of Sphaerium corneum, Linn. — 

 In a pool which stands in a field (locally known, I believe, by 

 the name of Spratt's Farm) near Hampstead Heath, on June 

 4th, I came across a pretty, and so far as I know, unnamed, 

 variety of Sphceriuni coi'neum. It is paler than the type, and has 

 the umbones shaded with brown colour, in which there are three 

 just-discernible bands forming segments of a circle, and of 

 darker brown. Externally to these and separated by a band of 

 ground-colour, is another similar band of the same tint as the 

 others but much better defined in outline. I purpose to name 

 this variety brim/teo-fasciata. — J. W. Williams, D.Sc. 



Helix lapicida L. var. albina. — This variety is to be 

 found in the vicinity of the old cathedral city of Wells, in Somer- 

 setshire. During 1883, on several occasions, and quite lately in 

 May of the present year, I have taken this white form on a loose 

 ivy-covered, stone wall on the old Bristol Road, just outside the 

 city. The variety is associated in this place with individuals of 

 a pale pinky brown colour, as well as with the ordinary dark 

 brown form. The pale brown specimens are the most frequent. 

 It is easy indeed to arrange a complete series which will show 

 every variation in colour from the dark brown to the purest 

 white. The wall in which this variety flourishes is composed of 

 rough blocks of liassic limestone, taken from a small pit close 

 at hand. — [Rev.] S. Spencer Pearce, B.A.
