Neptdnea decemcostata (Say). 



Fusus decemcostatus. Say (1826) ; et auct. 



Tritoniuin dccemcostatum, Stimpson (1851) ; but perhaps not of 



Middendorf. 

 Neptunea decemcostata, H. and A. Adams (1858). 



Bay of Fundy and Atlantic coast of Nova Scotia, from low-water to 45 

 fathoms, but not certainly known to occur so far northward as the Gulf of 

 St. Lawrence. The " Chrysodomus decemcostatus" of the writer's list of 

 mollusca dredged off Grande Greve in 1867 is certainly not that species but 

 N. despecta, var. tornata, and it is most probable that the specimens collected 

 by Logan near Cape Gaspe in 184:4 and referred by Bell to Fusus decemcos- 

 tatus, are also N. tornata. Verkruzen says that he found varieties of N. 

 decemcostata, with nine, eleven and twelve ribs, at Annapolis Basin, N.S,, 

 but that these are very rare. 



VoLUTOPSis NoRVEGiCA (Chemnitz), 



Fusus [Volutopsius) norvegicus, Morch (1857). 

 Volutopsis norvegica, G. 0. Sars (1878) ; et auct. 



One living but immi-ture specimen of this very rare shell was dredged 

 by the writer on the Bradelle Bank in 1873; and an adult, but very much 

 water worn example was taken off Bonaventure Island in 1872. 



In the Proceedings of the U. S. National Museum for 1886 (page 303) 

 Dall claims that the generic name Stromhella, Gray, should be preferred to 

 that of Volutopsius, Morch, (since changed to Volutopsis), but Verrill says 

 that Stromhella " had been preoccupied." 



SiPHO Stimpsoni (Morch). 



Fusus Cornells, Say (1831) ; non Linne, Pennant, &c. 

 Fusus Islandicus, Gould (1841) ; non L. 

 Tritonium Islandicum (Loven) Stimpson (1853). 

 Fusus Stimpsoni, Morch (1867). 

 Fusus curtus, Jeffreys (1867). 

 Neptunea curta, Verrill (1873). 

 Sipho Stimpsoni, Verrill (1881). 



Bay of Fundy, from low-water to 80 fathoms, Atlantic coast of Nova 

 Scotia, and Sable Island. In the Gulf of St. Lawrence, a small living 

 specimen (about 34 mm. in length) dredged by the writer in 1871 off 

 Charleton Point, Anticosti, in 112 fathoms, is apparently referable to this 

 species, though one of the specimens formerly referred by the writer to *S'. 

 curtus clearly belongs to the species since described by Verrill as S.pubescens.
