44 Habits of Testacellus Seiitulum. 



as they do ; and I think there is no doubt that they generally 

 get hold of them under ground, as the one above mentioned 

 had most likely been dragged to the surface by the worm. I 

 determined, however, to watch its motions ; but a heavy rain 

 coming on prevented me, and when the shower ceased they 

 had both disappeared. 



A few days ago, one was turned up with a spade, having 

 hold of a worm by the head, with about half an inch of it 

 swallowed ; the worm appeared quite alive and strong, and 

 turned the slug over with every twist of its body. The slug 

 kept its hold for some time, but ultimately quitted it, probably 

 in consequence of being disturbed. In digging up the spe- 

 cimens to send to you, one of them was cut with the spade, in 

 which a small slug was found of the common species.

 Stamford Hill, Nov. 30. 1831. Thomas Blair. 



The specimens communicated by Mr. Blair were very fine 

 ones. I had previously met with a single specimen at Notting 

 Hill Terrace, Kensington : it was crawling across the public 

 footpath, and appeared to have just quitted one of the little 

 gardens which front the houses in that place. I have since 

 learned that they are not very rare in the kitchen and forcing 

 gardens attached to the royal palace at Kensington, whence 

 I have seen specimens ; and a single living specimen was found 

 by Mr. Campbell, in the garden of the late Comtesse de 

 Vandes, on the 4th of October, 1832. On mentioning these 

 habitats to Mr. J. D. C. Sowerby, who possesses several pre- 

 served specimens, he stated that the only habitat from which 

 he had previously derived it is a garden in the Kennington 

 Road, Lambeth, where the individuals, although constant, are 

 never numerous : he farther remarked that it has also been 

 found beside the Hampstead Road. 



Shortly after I had acquainted Mr. Sowerby with the Ken- 

 sington habitat, his son, Mr. J. Sowerby, visited it, to collect 

 specimens ; and learned from Mr. Plimley, the distinguished 

 gardener of the forcing department, that they are compara- 

 tively frequent, although, on the morning on which he called, 

 which was a cold one, very few were above ground. Most 

 of those he saw were crawling on the gravel walks, with the 

 colour of which the colour of the slugs agrees. After he 

 had confined some individuals in a box, and kept the box a 

 short time in his pocket, he found, on opening it, that one of 

 the slugs had disgorged a worm ; probably, as he conceived, 

 in consequence of the heat communicated to the animal from 

 the pocket. I called on Mr. Plimley on December the 8th,
