sreater eligibilities of our county—that we should 
possess so many more of these animals than Dorset, 
(about 132 marine shells are enumerated by the 
author of the Dorset catalogue) itis certainly cu- 
rious to find some of the shells of Zetland and of 
the Orkneys generally, identified among the pro- 
ductions of South Devon, and so far as is known 
recognized no where else, witness the Buccinum 
glactale, Cingula vitrea, Cardium elongatum, §c. ; 
various species also have been found only in Scot- 
land and Devon, such as Venus granulata, Tellina 
punicea, &c., and again in the branchiferous mol- 
lusca, Aplysia punctata occurs only on the shores 
of Devon and Orkney. There is however no fact so 
worthy of observation and in great measure so in- 
explicable as the number of mulluscs exclusively 
found on the coasts of South Devon, or at most on 
the coasts of the two south-western counties of 
Great Britain, and on which IJ have above remarked.
