the Trondhjem Fiord. 351 



14. Alderia modesta^ Loven, Alder and Hancock, Mon. 

 Nudib. Moll. pi. xli. ; Forbes and Hanley, pi. 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 Eodberg. 



It does not occur in Sars's list of Norwegian MoUusca, and 

 has not, I believe, been previously met with in Norway. 

 Alder and tiancock write : " The species extends to Norway, 

 where it was discovered by Professor Lov^n ; " but this 

 seems to be a mistake, for Loven found it at Bohuslau, which 

 is in Sweden. The distribution of the brackish-water fauna 

 has a peculiar interest.
