Moll, 115 
investigated, are poorer in species than either Shetland or the south- 
west. Cellaria Jistulosa, Microporella ciliata, M, malusii, and Caberea 
harii are remarkably widely distributed in the temperate and tropical 
zone, but not abyssal. About 60 of the recent British species have been 
thus far recorded from tertiary beds, 2-3 from the cretaceous epoch.
