complicated with the presence of the more modern scheme 
of fasciation, as the space between the upper and lower 
group of bands of the ancient band arrangement is not 
coincident with that separating the modern banding, 
but invariably occupies a higher position on the whorl, 
so that the modern dark peripheral or third band is de- 
veloped almost in the centre of the formerly existent 
peripheral space, which is thus really supra-peripheral 
and clearly indicates a former approximation in band 
arrangement to that which now characterizes the some- 
what more primitive yet sub-dominant South-Huropean 
genus Campyloea.”
