Note on Testacella Maugei Fe'r. — I have just received 

 from a correspondent in Somerset a living Testacella — presumably 

 Maugei — and have been making some experiments on it. On 

 gently pressing the head with a pencil it showed signs of irritation 

 by forcing out a quantity of frothy mucus from the margin of the 

 shell, on continuing to tease it, it extruded its odontophore for 

 almost a quarter of an inch and then gradually withdrew it, this 

 was repeated several times; I then procured a worm, thin, but 

 about three inches long, I rubbed the worm gently across the head 

 of the Testacella and the tongue was again rapidly extended and 

 the victim transfixed, the odontophore was then withdrawn as 

 before, carrying with it the struggling worm which made every 

 effort to escape, but without success, in about 5 minutes all had 

 disappeared except the head which was rejected. — J. Darker
