BRITISH MOLLUSKS. 



very generally in South- Western Europe, principally in the vicinity 

 of maritime cities. 



2. Testacella Maugei. Manges Testacella.

 epidermis.

This species, a native also of the Canary Islands, has not been yet 

 included in the British fauna, nor does M. Moquin-Tandon admit 

 it into that of France. More than fifty years have elapsed since it 

 was transported with plants into the nursery grounds of Messrs. 

 Miller and Sweet, of Clifton, and it has become naturaHzed in several 

 localities in the West of England. Mr. JN"orman, writing in 1859 

 to Mr. Jeffreys, says : — "I have had as many as five dozen sent to me 

 alive at the same time." The animal is of a darker mottled colour 

 than the preceding species, and the shell is of a more oblong com- 

 pressed form, larger and more produced at the umbo. 



Our figure is from a drawing made by the Rev. M. J. Berkeley, 

 as long back as 1829, from a living specimen of rather small dimen- 

 sions, collected by Mr. Sowerby, in which the shell is held in the 

 embrace of two external lateral lobes ; and I have observed the 

 dried remains of a similar condition of the mantle in a specimen 

 collected by Mr. Metcalfe.
