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 Bellardi'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. 



P. 390. P. SEPTANGTJLAEIS. F. Belfast (A. Bell) ! ; N. of 

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



P. 392. P. ETTFA. F. Ked Crag at Butley, Selsea, and 

 Portrush (A. Bell) ! ; Killiney (Walpole) ! ; G. Naples (Tiberi 

 and others) ! P. rufescens, De Bl. 



p. 394. p. pyramidalis. F. Killiney (Walpole) ! Fusus 

 rufus, Gould. 



p. 395. P. TUEEICULA. N. of Hebr., 550 f. (C. and T.). 

 F. Labrador (Packard, as Bela exarata). E. Arcachon (La- 

 font) ! ; Labrador, 4-30 f. (Packard). Montagu's and Dono- 

 van's names were published in the same year, 1803. 



p. 398. P. TEEVELYANA. N. of Hebr., 189 f. (C. and T.). 

 Not Fusus decussatu, Couthouy, which has flexuous ribs and 

 a much finer sculpture ; this has been dredged by Carpenter 

 and Thomson in 500 and 550 f., between 60 and 61 N. lat., 

 and by G. 0. Sars in 300 f. among the Loffoden Isles. 



P. 400. MAEGINELLA. Deshayes and Philippi have since 

 separated Erato from this genus. 



p. 403. CYPEJEA EUEOPJEA. N. of Hebr., 189-530 f. 

 (C. and T.).
