OF WILLIS’ PUBLISHED PAPERS—GANONG. 415 
everything in the Colonial Review list is in the list below, and 
the latter includes ten names not in the former, 7. ¢., Nos. 4, 55, 
57, 78, 87, 158, 196, 199, 200, 201, of the following list. It 
therefore included 193 names, a large advance over the 1857 
list, which included 91. Further comment on this list is need- 
less, since its substance is embodied in the one below. It has 
probably been seen by very few naturalists. 
Another list of Economic Mollusca of Nova Scotia, which was 
probably written by Willis, appeared in the Catalogue of the 
Nova Scotian Department of the International Exhibition of 
1862 (Halifax, 1862, p. 13). The list includes 18 species, with 
notes on their abundance, and it is stated that they are to be 
furnished by J. R. Willis. 
(5). 1863. NovaScotiaShells. Privately printed list, issued 
in November, 1863. 
This is Willis’ latest, longest, and in all ways most important 
list of Nova Scotian Molluses, and it is reproduced in full, word 
for word, below. It was printed on a single sheet, 14x8 inches 
in size, with the introductory notes printed across the top of the 
entire sheet and the list itself arranged in three columns. Mr 
Piers has found amongst Willis’ correspondence, now in possession 
of Mrs. Willis in Halifax, several newspaper clippings and letters 
of acknowledgment from various persons to whom the list was 
sent, the dates of which make it certain that it was issued in 
November, 1863. It is this list which has been quoted by various 
writers. As Mr. Piers suggests, he appears to have taken his 
Colonial Review list (No. 4), and having struck out two names, 
to have added some others with additional notes on distribution, 
etc., and to have published this as the list we are now considering. 
As already referred to, the list is now very rare, no large 
libraries owning copies. The only copies known to us are those 
belonging to Mrs. Willis of Halifax, to Sir William Dawson, to 
Mr. Dall of Washington, and to the editor of these notes, into 
whose hands it came from the library of the late J. Matthew 
Jones, as the gift of the son of the latter. Each of these copies 
has pen and ink corrections of misprints, ete, by Willis himself, 
none of which are important.
