Assistant Biologist to the Essex County Council. 

 [Continued from volume iv., page 76] 



In a previous paper dealing with the distinctive characters of 

 our three species of worm-eating slugs, the writer expressed his 

 intention of following out the distribution of these forms in the 

 British Isles, and more particularly of the true Testacella haliotidea: 

 it is intended to give here, a provisional list of localities from 

 which the writer has received undoubted specimens of the last 

 species, together with some records supplementing those 

 given by Mr. Taylor''' for T. scntiiluiii, and a few for 

 T. mangei. 



Testacella haliotidea, Draparnaud. 

 Devonshire. The Castle, Tiverton (Captain L. Moore). 

 Kent. Shoreham Vicarage, Sevenoaks (Rev. R. Ashingdon Bullen). 

 Surrey. Nutfield Priory, with T. scutuluni (J. Moffat). This is the only 



locality from which more than one species has been received. Mr. J. 



Scarlett, of Tasburgh, near Norwich, who told the writer of this locality, 



remembered the occurrence of worm-eating slugs at Nutfield 15 or 16 



years ago. They were most plentiful in asparagus beds. 

 Surrey House, Leatherhead (C. A. Brigg, M.A.). 

 II, Harrow Road, East Dorking (C. J. Howell). 

 Kew Gardens (the Writer). 

 Essex. Widford Lodge, Widford (E. Hammond). 



A dozen specimens were found 18 inches below the surface in a bed 

 9 feet in diameter on a lawn. 

 Stisted (Basil F. May). 

 Colchester (W. Patterson). 



The specimens from the last two localities approached T. scutuluni 

 in colour. 

 Suffolk. Dallinghoo Rectory (Rev. R. Ashingdon Bullen). 

 Norfolk. Diddington Hall, Brandon (A. Tanner). 



One very dark-coloured specimen. 

 Worcestershire. Worcester (J. Lloyd Bozward), Elmfield. 

 London Road, Worcester (C. H. Webber). 

 Hagley Hall, Stourbridge (D. R. Dixon). 

 Cheshire. Arley Hall, Northwich (J. V. Smith). 

 Yorkshire. Sandbeck Park, Rotherham, in Trent drainage (Geo. Summers). 



Walk-upon-Dearne, 12 miles from the last locality, in " Don 



drainage" (W. McKeigh Jones). 

 Stirlingshire. Brentham Park, Stirling (David Bruce).
