TESTACELLA, 89 



where Into this country in soil at the roots of shrubs 

 and other plants, there are, I think, some grounds for 

 believing it to be indigenous in Great Britain. A few 

 years ago, when on a visit at Woolverstone Park, in 

 Suffolk, the seat of my kind and hospitable friend 

 Mr. Berners, the head gardener informed me that he 

 had recently observed several curious slugs in a bed 

 in one of the vineries, and that they usually came to 

 the surface after the soil had been watered. They 

 proved to be T, haliotidea. I ascertained that the 

 bed had been emptied a short time previously, and 

 replenished with loamy soil brought from a field in 

 a remote part of the estate, and far distant from 

 gardens, shrubberies, or plantations of any kind. 

 Until the introduction of this soil the molluscs had 

 never been seen by the gardener or his assistants, 

 who naturally wage incessant war against slugs of 

 all sorts, so that it is more than probable that they 

 had been brought to the vinery from the field, where, 

 owing to its position, it is not at all likely they could 

 have been introduced. 



This species varies considerably in colour, as well 

 as in the shape of the shell. 



Var. sciituliun, Sowerby. — Body yellowish speckled with 

 brown. Shell narrower, spire more produced and pointed, B.C. 



2. T. Maugei, F£russac. 



Body dark brown, head smaller than that of T. haliotidea. 

 Shell larger and more cylindrical. 



Inhabits nursery gardens near Bristol and other 

 places ; it occurs in fields near Devizes (Cunningham 

 fide Woodward).
