Species of Mollusca obtained in Corunna Bay: by r. 

 m'andrew and h. woodward. 



Among the loO species enumerated are Cassis Sahuron, Lam., 

 " agrees exactly with Reeve's description and figure, but 

 locality given for latter — Japan ;" Cyprsea condidula, Gask., 

 frequent at one particular locality. The species inhabits the 

 Madeira and Canary Islands, and has not previously been de-

 for the first time, on the Atlantic coasts north of Gibralter. 



The genera Ringicula, Mitra, Solarium, Solemya, and the 

 species Cyprsea candidula, Scalaria crenata, Dentalium dentate^ 

 Auricula Firminii, Cliitonfulvus, Cardium ciliare and Lucina 

 digitalis are supposed here to reach their northern limit, while 

 Lucuna puteolus is the only northern species which reaches its 

 southern limit in the neighborhood of Corunna. 



Cassis, Murex Edwardsii, Purpura hivmasfoma, Mangelia 

 elegans and Lucina pecten have been found on the coast of 

 Asturias, and appear to extend to the Spanish or French
