18 TESTACELLA SCUTULUM. 
Geographical Distribution.—The European area of distribution of 
this species cannot be stated with accuracy owing to the very prevalent mis- 
conception of its characters. = 
Under Risso’s name of 7. bisulcata, this species has, if i re 
however, been recorded as being very common through- i a (\ 
out the south of France, and as inhabiting Italy, w/ X& 
Spain, and Algeria. Fic. 30.—Testacella bi- 
Testacella pecchiolii, T. gestroi, T. fischeriana, and — sxieata Risso x 2 (after 
probably other south European forms are, if not abso- ?"?"” 
lutely identical, closely allied and more primitive forms of our species, and 
may be regarded as varieties. 
The British distribution of 7. scatulum is less restricted than that of the 
other species ; it has been found scattered over England, and its existence 
verified in Ireland and Scotland, but it would seem to be especially preva- 
lent in and characteristic of the Metropolitan district.
