The usual diameter of Helix hortensis is three- 

 quarters of an inch. 



Helix nemoralis var. hybrida (The Brown 

 Mouthed Snail) seems to form a connecting link be- 

 tween H. nemoralis and H. hortensis. Its character is 

 intermediate between these shells. The colour is brown, 

 or yellow with brown bands ; the edge of the aperture 

 is pale brown, and the colour internally usually pink. 



Two specimens only have been found here ; near 

 Highfield House. 



It is found at Stella, near Newcastle (Alder), Kent 

 and Dorset (Montagu), London (Grey), Norwich 

 (Bridgman), and Halifax (Leyland). 



Neither this nor Helix hortensis are so common as 

 Helix nemoralis. 



Other varieties have been recognized by some authors, 

 as the one banded, known as the Helix cinctaof Shep- 

 pard, and the five-banded, the Helix fasciata of Shep- 

 pard ; the latter two named can hardly be recognized 

 even as varieties. It is possible, say some authors, that 

 the variety hybrida may be the hybrid progeny of Helix 

 nemoralis and Helix hortensis. One circumstance, 

 however, convinces me that this is not the case, for I 

 found the variety hybrida in the Starhills, near Lytham , 

 where Helix nemoralis is extremely abundant, and 

 where the variety hortensis is not found. 



There are several curious facts observable on the 

 Star-hills with respect to Helix nemoralis : they are re- 

 fiiarkably small, frequently have the epidermis worn off
