14. Alderia modesta, Lovén, Alder and Hancock, Mon. 
Nudib. Moll. pl. xli.; Forbes and Hanley, pl. CCC. fig. 1. 
Mr. Scott found a specimen of Alderia in a shallow pool 
into which the sea only broke at spring tides. This pool was 
in the little indentation of the coast just north of Rédberg. 
It does not occur in Sars’s list of Norwegian Mollusca, and 
has not, I believe, been previously met with in Norway. 
Alder and Hancock write: ‘ The species extends to Norway, 
where it was discovered by Professor Lovén;” but this 
seems to be a mistake, for Lovén found it at Bohuslin, which 
is in Sweden. ‘The distribution of the brackish-water fauna 
has a peculiar interest.
