THE ECONOMIC MOLI/USCA OF ACADIA. 
10 
An interesting part of the present subject is that of local 
names for our Mollusca. As soon as a species comes to be 
much used, it requires a special distinctive name, and such 
the fishermen generally give it. As so few of our own Molluscs 
are utilized for any purpose, very few of them have common 
names, and in such cases we have felt at liberty to adopt for 
those lacking them, the best of those by which they are 
known to English fishermen. The writer would be very 
thankful for any information which could be given him as to 
local names applied to Mollusca in any part of these pro- 
vinces. 
We believe no explanation is needed of the use of the word 
Acadia throughout this paper. The three maritime provinces 
are, zoologically, botanically and geologically one, and a term 
by which they can be collectively designated is a necessity in 
scientific if not other writing. Several writers on the natural 
history of the region have employed the word Acadia, and 
what more appropriate name can ever be used?

[This part dealing with Mollusca is in reality by Willis, for Mr. 
Knight says: “ The author is indebted to J. R. Willis, Esq., 
of Halifax, for the following ample description of our Edible 
Mollusca, which has already been published in a colonial peri- 
odical.” Can any of our readers tell us what this periodical 
was, and its date? We have not been able to find any trace 
of it.]
