222 SUPPLEMENT. 



Piacenza and the Vienna basin, regarding this species as the 

 Fusus modiolus of Jan ; and he cites Sismondi for another 

 synonym, P. acuta, Bellardi. But Jan's name is taken from a 

 catalogue only, and I am not aware that he ever described the 

 shell; and JBellardi's description certainly does not suit our 

 species, which is not varicose, nor is the canal striated. E. 

 Norway, 30-300 f. (M' Andrew and Sars). The animal is 

 much more shy and easily alarmed than P. nivalis, which 

 lives with it.

 Italy (Bellardi and Manzoni). Not P. Bertrandii, Payr.

 Not Fusus decussatus, Couthouy, which has flexuous ribs and

 and by G. O. Sars in 300 f. among the Loffoden Isles.
