A CURIOUS HELIX. 
In The Journal of Conchology for October, Mr. A. J. Arkell 
illustrates an interesting Helix mnemoralis with deformed 
tentacles. The upper pair are conjunct for half their length, 
thus forming a fork, like the letter Y. The lower tentacles 
are even more abnormal, for where the right tentacle would 
normally be, there is a kind of irregular reproduction of the 
upper fork, the right prong being much bigger than the left 
one; both these prongs possess the characteristics of tentacles. 
On the other hand, where the left tentacle would normally be, 
there is a small protuberance, which only resembles a tentacle 
in that it is somewhat retractile. This is the only feature 
not shown in the drawing, which is x3. In all other respects 
the snail is apparently quite a normal five-banded example. 
By the kindness of the Editor of the Journal we are able to 
give a reproduction of this illustration.
