TAYLOR : LIFE HISTORY OF HELIX ASPERSA. 10 1 



Miss F. M. Hele says " I found near Bristol a very beauti- 

 ful mature reversed specimen, unfortunately dead and slightly 

 injured. I had a similar specimen sent me from Bath not long 

 after, and my sister. Miss Jessie Hele, has found one at West- 

 bury. She tried to increase the variety, but it was of no avail, 

 the eggs when hatched always producing dextral shells. 



Dr. Jeffreys says Mr. Bridgman reared a young one to 

 maturity on cabbage and lettuce leaves. The specimen will 

 probably have been found near Norwich. 



In France it has been found at Dax, Le Mans, and other 

 places, and Dr. Jeffreys states that M. D'Orbigny had a colony 

 in his garden at Rochelle. 



Monst. scalariforme Taylor. Shell with the spire produced and whorls 

 disunited. 



Dr. Jeffreys, Rimmer, &c., merely remark that this 

 monstrosity occasionally occurs, but give no further particulars. 



Miss Hele writes in reference to this form : "I have found 

 near Bristol two shells approaching the ram's horn variety shown 

 in the British Museum. One I have in my collection, the other 

 I unfortunately lost through an accident. 



In the Journal de Conchyliologie an account is given of a 

 specimen of this form, which was entirely detached from its shell 

 and continued healthy and active. 



Animal. 



The body is oblong, narrow, rounded in front and pointed 

 behind ; of a blackish-grey on the anterior upper surface — some- 

 times yellowish-green, occasionally with the head fawn coloured 

 and the bodypellucidlavender-grey — with about fourteen oblique 

 rows of oblong, but irregularly shaped tubercles on each side, 

 the summits of which are perceptibly paler. Towards the margin 

 of the foot and the ends of the body the colouring is paler and 

 has often a greenish or yellowish tinge, the granulations be- 

 coming more rounded and closer.
