Geographical Distribution. — This species is known to range over 

 western and south-western Europe and North Africa, and also to extend 

 into Germany, Switzerland, and Belgium, which 7'. scatulum or T. maurjfi 

 are not known to do ; this peculiarity in its distribution probably indicates 

 its later evolution, a circumstance apparently confirmed by its more 

 advanced internal organization. 



T. haliotidea is recorded from Western Germany, Belgium, Switzerland, 

 France, Italy, Dalmatia and Adriatic States, Corsica, Spain, Portugal, 

 ^Vlgeria, Madeiras, and Canaries, but the confusion that has always reigned 

 in this genus makes many of the specific identifications of doubtful accuracy. 



It has also been recorded from Nova Scotia and from Philadelphia, U.S.A., 

 doubtless introduced. 



The distribution in the British Isles is probably very complete over the 

 southern and western districts of England, but the records are incomplete 

 and many unreliable ; undoubted examples have, however, been found in 

 various parts of England, the south of Scotland, the south and east of 

 Ireland, and south of Wales.
