With the exception of Witchellia jugifera all these species 
have been found in Dorset. 
In the Cotteswold district, after the close of the Opalinum- 
zone, conditions seem to have been distinctly unfavourable to 
the residence of Ammonites; and it seems not improbable 
that the specimens were not actual inhabitants, but found 
their way, or were by some means brought into the district, 
from other areas. The number of specimens discovered is 
extremely small, and their condition of preservation very poor, 
so that identification is a matter of uncertainty. It may be 
interesting to notice the species.
