The shell which I have designated above under the name of Fusus contra- 
vius I believe to be distinct from the reversed var. of F’. antiquus. 
Of the species not British, at least twenty have been found in the Medi- 
terranean ; the exceptions are marked * in the list, and of these two, viz. 
Fusus contrarius and Buccinum, new species (which may be a var. of B. mo- 
destum), I look upon as doubtful. 
The subjoined list contains thirty species found at Vigo, and not known to 
inhabit the Mediterranean. Six of them may be considered doubtful, viz. 
Fusus contrarius and Buccinum (new ?), for the reasons already mentioned ; 
Natica monilifera and Lacuna puteolus, because they are in the Vigo list 
upon the faith of single, old, dead and imperfect specimens; Natica Alderi 
and Pecten obsoletus, because possibly identical with N. Marochiensis of 
authors, and a Pecten procured at Gibraltar. 
The twenty-nine species procured at Vigo, but not, in the Mediterranean, 
all inhabit the British seas except six or seven (marked * in the list), Fusus 
contrarius being doubtful.

From the foregoing lists, it appears that the marine fauna of Vigo, as 
regards Mollusca, is more nearly related to that of the British Isles than to 
that of the division in which it is situated, the Lusitanian. 
The only land shells I met with in the neighbourhood of Vigo, are,— 
Helix nemoralis. 
barbula. 
—— revoluta. 
Helix aspersa. 
caperata. 
—— cellaria.
